feat(linstor, platform): upgrade snapshot-controller to v8.7.0 and enable VolumeGroupSnapshots - #5239
Windows VMs with three or more disks cannot get an application-consistent Velero backup on Cozystack today. Velero takes one CSI snapshot per PVC, one after the other, while virt-freezer holds the guest frozen, and on LINSTOR each snapshot takes 2 to 4 s. With three disks or more the freeze runs past the 10 s that Windows VSS allows, VSS aborts with 0x80042314, and the backup fails. The only workaround is kubevirt.io/skip-backup-hooks=true on the VM, which gives up application consistency.
The fix is a VolumeGroupSnapshot: one snapshot request for all the PVCs of a VM, taken inside the freeze. linstor-csi has implemented the CSI GroupController since v1.11 (the package ships v1.11.2), and it creates the whole group in a single LINSTOR Resources.CreateSnapshots call, so every volume of the VM is captured at the same instant and the freeze lasts one snapshot instead of N. Velero 1.18 drives VolumeGroupSnapshots through groupsnapshot.storage.k8s.io/v1beta2. What is missing is on the Cozystack side: snapshot-controller v8.0.1 serves the group snapshot API only as v1alpha1 and runs without the CSIVolumeGroupSnapshot gate, and piraeus-operator turns the gate off on the csi-snapshotter sidecar when it does not find v1beta2.
This PR:
Upgrades the vendored Piraeus snapshot-controller chart from 3.0.5 (v8.0.1) to 5.4.0 (v8.7.0) with the package's make update. The snapshot.storage.k8s.io CRDs stay at v1. The groupsnapshot.storage.k8s.io CRDs go from v1alpha1 only to v1beta1, v1beta2 and v1, with v1beta2 as the storage version. The controller runs with --feature-gates=CSIVolumeGroupSnapshot=true, the chart's default. The validating webhook is gone upstream, replaced by CEL rules in the CRDs. The new optional conversion webhook stays disabled, as upstream ships it, since no cluster holds group snapshot objects to convert.
Sets keepCRDs: true. The chart now renders its CRDs from a template instead of crds/, so without it an uninstall of the release would delete every VolumeSnapshot with the CRDs.
Patches the vendored CRD template (patches/skip-foreign-crds.diff, applied by make update) so a CRD is rendered only when it is absent or already carries this release's meta.helm.sh/release-name and meta.helm.sh/release-namespace. A CRD a distribution ships, or that another release owns, stays out of the manifest, so helm-controller neither takes it over nor rewrites it on upgrade. On a fresh install, and for the CRDs migration 61 adopts, the output is unchanged.
Adds migration 61 and bumps migrations.targetVersion to 62. The CRDs crds/ created carry no Helm ownership metadata, and the patched chart renders only the CRDs that do, so the migration annotates the three snapshot.storage.k8s.io CRDs the release installed for adoption, which keeps them in its manifest. The three group snapshot CRDs cannot be adopted: the apiserver rejects an update that drops v1alpha1 while it is listed in status.storedVersions. The old controller never ran with the gate, so no v1alpha1 object was ever acted on, and the migration deletes each of these CRDs when it is empty and creates it again straight away at v1beta2, from copies make image-migrations renders out of the snapshot-controller chart with the release's ownership metadata (as it already bakes the etcd-operator CRDs for migration 50). Every HelmRelease waits for this pre-upgrade hook, so the linstor release renders against the v1beta2 API even when it upgrades before snapshot-controller. A CRD that still holds objects is kept and recorded on the cozystack-version ConfigMap as cozystack.io/migration-61-needs-attention, and the CRD stays out of the release, which carries no Helm ownership on it, so snapshot-controller still upgrades with that group snapshot API at v1alpha1 and group snapshots off. Nothing re-renders either release once the CRD is cleaned up, so the migration's warning gives the whole recovery: delete the objects and the CRD, force a snapshot-controller HelmRelease upgrade so the chart creates the CRD at v1beta2, restart the snapshot-controller Deployment, which sets up its group snapshot watches only when it starts, then force a linstor HelmRelease upgrade. The migration only touches CRDs that helm-controller labelled as installed by cozy-snapshot-controller/snapshot-controller, and the chart leaves the others out of the release, so a distribution that ships its own snapshot CRDs keeps them in both places. Whether the release is installed is read from its HelmRelease rather than from those labels, so a retry after a failed create still recreates the group CRDs it deleted when only they carried the labels; without the HelmRelease the migration changes nothing.
Sets FEATURE_GATE_CSI_VOLUME_GROUP_SNAPSHOT=true on the linstor-csi csi-snapshotter sidecar through the LinstorCluster pod template. piraeus-operator v2.10.2 probes for the v1beta2 API once, when it starts, and adds a patch that sets the variable to false when the probe fails. On a cluster upgraded from v1alpha1 the operator started before the new CRDs existed, so the gate would stay off until the operator next restarted. The pod template is merged after the operator's own patch. The variable is always set, to true only when the apiserver serves all three groupsnapshot.storage.k8s.io/v1beta2 kinds and to false otherwise: the operator's probe looks at VolumeGroupSnapshot alone, and csi-snapshotter with the gate on and a group API missing waits for its group snapshot caches before it starts the ordinary snapshot workers. The class below renders under the same check.
Adds a default VolumeGroupSnapshotClasslinstor-group-snapshots for linstor.csi.linbit.com, next to the existing linstor-snapshots VolumeSnapshotClass, with the velero.io/csi-volumegroupsnapshot-class: "true" label Velero selects a group snapshot class by. Only on a cluster where migration 61 kept a populated v1alpha1 CRD do they wait for the forced linstor upgrade at the end of that recovery.
Not in this PR: grouping a VM's PVCs for Velero. Velero builds a group from the PVCs that share the value of the velero.io/volume-group label, so the vm-instance and vm-disk charts would have to set it to the VM name on every disk. That is a separate change, and an operator can set the label by hand meanwhile.
Testing:
Kubernetes v1.34.3, Velero 1.18.1, linstor-csi v1.11.2, piraeus-operator v2.10.2. On that cluster the group snapshot CRDs are v1alpha1 only, list ["v1alpha1"] in storedVersions, hold no object, and carry the helm-controller labels of cozy-snapshot-controller/snapshot-controller. The csi-snapshotter sidecar runs with FEATURE_GATE_CSI_VOLUME_GROUP_SNAPSHOT=false, set by the operator's patch.
hack/migration-61-snapshot-crds.bats (15 cases) runs migration 61 in the migrations base image against a fake kubectl that keeps the CRDs in a state file: adoption and deletion, a second run that changes nothing, a CRD holding objects, CRDs another installer owns, CRDs that already serve v1beta2, a cluster without the release, a release without the group CRDs, a failing HelmRelease read, CRD read or delete that aborts before the stamp, a failed diagnostic record that still stamps, a failed create that aborts and is completed by the retry, release labels on the group CRDs alone, with and without a failed first create, and a v1beta2 CRD that still stores v1alpha1, which is recorded rather than adopted. With the delete removed from the migration, the first case fails; against the previous revision, which took the release identity from the CRD labels, the failed-create case with group-only labels stamps 62 without recreating the CRDs and fails.
New helm-unittest suites: packages/system/snapshot-controller/tests/crds_test.yaml pins keepCRDs, v1beta2 served and stored on the three group snapshot CRDs and the controller gate; packages/system/snapshot-controller/tests/crd_ownership_test.yaml mocks the live CRDs and checks that one without Helm ownership and one owned by another release are left out while an absent one and one this release owns are rendered (it fails with the patch reverted); packages/system/linstor/tests/volume_group_snapshot_test.yaml pins the sidecar gate on with and without strict topology, off when only VolumeGroupSnapshot or no group API is served, and the VolumeGroupSnapshotClass rendered only when the v1beta2 API is served. csi-topology_test.yaml now counts the csi-snapshotter entry in the pod template.
helm unittest passes for packages/system/linstor (28 tests), packages/system/snapshot-controller (7) and packages/core/platform (285). hack/cozystack-version-stamp.bats and hack/check-migrations-target.sh pass.
Not yet run end to end: the upgrade of a live cluster through migration 61, and a Velero backup with a VolumeGroupSnapshot through linstor-csi.
A correction to the first commit, 198d8ac, whose message says Helm refuses to upgrade over the existing CRDs because they carry no ownership metadata: that is wrong for this platform. The helm-controller release builders enable takeover by default, so the release would have taken the CRDs over, distribution-owned ones included. What keeps those out of the release is the chart patch in 0d2e0ca (patches/skip-foreign-crds.diff), and what keeps the CRDs the release installed in it is the adoption in migration 61. The commit is not reworded, since the branch is under review and is not force-pushed.

Downstream repositories
No downstream repository is affected by this change
The only change to packages/core/platform/values.yaml is the value of migrations.targetVersion. The website's platform-package.md lists that key without a value, so it needs no change. No website page mentions VolumeGroupSnapshots or documents the snapshot-controller webhook. The rest of the diff is a vendored chart, two system packages, a migration and its tests, none of which the trigger map reaches.
Release note
feat(platform): snapshot-controller is upgraded to v8.7.0 and serves VolumeGroupSnapshots as groupsnapshot.storage.k8s.io/v1beta2, and linstor-csi takes group snapshots with a default VolumeGroupSnapshotClass labelled for Velero. A platform migration hands the snapshot CRDs over to the release and removes the empty v1alpha1 group snapshot CRDs.
Summary by CodeRabbit
New Features
Added LINSTOR volume group snapshot support when all required APIs are available, including a default snapshot class.
Updated the snapshot controller to support newer snapshot APIs and a conversion webhook.
Added safer CRD installation and upgrade handling, preserving CRDs with existing objects and recording items that need attention.
Bug Fixes
Improved snapshot-controller upgrade reliability, including recovery from certain CRD creation failures.
Documentation
Updated chart guidance for CRD management, conversion webhooks, and snapshot class configuration.
snapshot-controller v8.0.1 serves VolumeGroupSnapshots only as
v1alpha1 and runs without the CSIVolumeGroupSnapshot gate, so no CSI
driver on the platform can take a crash-consistent snapshot of several
volumes at once. Velero 1.18 and piraeus-operator both look for
groupsnapshot.storage.k8s.io/v1beta2, which v8.7.0 serves and which the
upstream chart enables by default.
The chart now renders its CRDs from a template instead of crds/. Helm
refuses to take over objects that lack its ownership metadata, and the
apiserver refuses to drop v1alpha1 from CRDs that list it in
storedVersions, so migration 61 adopts the snapshot CRDs the release
installed and deletes the v1alpha1 group snapshot CRDs when they are
empty. keepCRDs is set because an uninstall would otherwise delete
every VolumeSnapshot along with the CRDs.

linstor-csi implements the CSI GroupController since v1.11 and creates
the snapshots of a group in one LINSTOR call, so the volumes of a
multi-disk VM are captured at the same instant. Velero needs that for
application-consistent backups of Windows VMs with three or more
disks: taken one by one, the snapshots outlast the 10 s VSS allows a
freeze.
piraeus-operator decides the csi-snapshotter gate from an API probe it
runs only at startup, so on an upgraded cluster the gate would stay
off until the operator restarted. The gate is set in the LinstorCluster
pod template instead, and a default VolumeGroupSnapshotClass carries
the label Velero selects a group snapshot class by.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The snapshot-controller chart now renders CRDs as resources and replaces validation-webhook resources with conversion-webhook resources. Migration 61 adopts or recreates eligible CRDs and advances the target version to 62. LINSTOR conditionally enables group snapshot support when all three v1beta2 APIs are served.
Changes: Snapshot controller and group snapshot support
The chart renders and retains CRDs as resources, removes the static CRD manifests, and updates upgrade guidance. Build rules stage the three group-snapshot CRDs. Tests cover rendered CRD versions and ownership.
Controller resources specify the release namespace. Snapshot-class values move to the chart top level. LINSTOR enables the CSI feature gate and renders a VolumeGroupSnapshotClass when all required v1beta2 APIs are available.

The new class is unconditionally marked as a default. A cluster with an existing default group-snapshot class for the LINSTOR driver may consequently have two defaults, making class selection for snapshots without an explicit class ambiguous or invalid.
Creation of those group snapshots may be rejected instead of selecting the pre-existing default.
This can occur when: An operator previously configured another LINSTOR VolumeGroupSnapshotClass as the default and creates a group snapshot without specifying a class after this chart is installed.

Not changed: nothing in the platform creates group snapshots before this upgrade. The old snapshot-controller ran without the CSIVolumeGroupSnapshot gate and linstor-csi's sidecar had it off, so a v1alpha1 object could only come from a hand-made create landing between the empty check and the delete, inside one pre-upgrade hook. Blocking creates for that window would need an admission policy that outlives the migration, which costs more than the risk; leaving the thread open for a maintainer to decide.

@mattia-eleuteri Thanks for explaining the trade-off. The migration still has a small risk of losing an object created between the empty check and CRD deletion.
I’ll leave the thread open for a maintainer to decide whether to accept that risk.
…rved
The linstor release can upgrade while snapshot-controller still serves
the group snapshot API as v1alpha1: migration 61 keeps a CRD that holds
objects, and the snapshot-controller release stays Ready on its old
revision until it upgrades. With the gate on and the API missing,
csi-snapshotter waits for its group snapshot caches before it starts
the ordinary snapshot workers, so every VolumeSnapshot would stall, and
the v1beta2 VolumeGroupSnapshotClass would fail the linstor upgrade.
Both now render only when the apiserver serves the three v1beta2 kinds;
otherwise the operator's own probe decides the gate.

Pin the v1beta2 storage version on all three group snapshot CRDs, not

that path.

Ensure LINSTOR upgrades again after the API becomes available.
If LINSTOR upgrades before snapshot-controller serves v1beta2, the chart omits the feature gate and VolumeGroupSnapshotClass. The existing dependency can be Ready on the old revision. A later CRD upgrade does not force LINSTOR to render again, so group snapshots can remain unavailable until another LINSTOR upgrade.
Trigger a LINSTOR upgrade after all three APIs become available. An ordinary Flux reconcile alone is not sufficient.

Update the LINSTOR chart’s upgrade-triggering input to change when all three
`groupsnapshot.storage.k8s.io/v1beta2` APIs become available, so Flux performs a
Helm upgrade rather than only reconciling the existing revision. Preserve the
existing capability checks for rendering the feature gate and

9256c29 makes the API available before either release renders instead of re-triggering linstor: migration 61 creates the group snapshot CRDs at v1beta2 right after deleting the v1alpha1 ones, from copies the image build renders out of the snapshot-controller chart with its ownership metadata, and every HelmRelease waits for that pre-upgrade hook. Only a cluster where the migration kept a populated v1alpha1 CRD still needs a later linstor upgrade, and that cluster already needs manual clean-up.

@mattia-eleuteri I checked the current code. When no CRDs need attention, migration 61 recreates the empty, release-owned group snapshot CRDs and waits for them to become established before the platform hook completes.
The manual-recovery case still needs a LINSTOR upgrade if LINSTOR rendered before the APIs became available. After snapshot-controller serves all three v1beta2 APIs, a forced Helm upgrade—not an ordinary Flux reconcile—will rerender LINSTOR.
Please verify that recovery path in a live-cluster upgrade. The PR summary says that test has not yet run.
The linstor release renders its group snapshot gate and
VolumeGroupSnapshotClass only when the v1beta2 API is served. Its
dependency on snapshot-controller can be satisfied by the old Ready
revision, so linstor could render before the new CRDs exist, and
nothing would render it again once they did. Every HelmRelease waits
for the platform's pre-upgrade hook, so migration 61 now creates the
CRDs it deletes straight away, from v1beta2 copies the image build
renders out of the snapshot-controller chart with that release's
ownership metadata. Both releases then render against the v1beta2 API.

The version assertions matched v1beta2 as the storage version but not
as served, so a chart that stored v1beta2 without serving it would
pass while the linstor release saw no API to enable group snapshots
against.

Leaving the gate to piraeus-operator while the API was incomplete was
not safe: the operator probes only VolumeGroupSnapshot, so with that
kind served and the content or class kind still at v1alpha1 it turns
the gate on, and csi-snapshotter stalls ordinary snapshots waiting for
the missing caches. The pod template now always sets the variable, on
only when all three kinds serve v1beta2.

Handle stored versions before adopting the CRD.
If a release-labelled group CRD serves v1beta2 but still lists v1alpha1 in status.storedVersions, migration 61 adopts it unchanged. For a release using server-side apply, the chart then removes v1alpha1 from spec.versions, and Kubernetes rejects the upgrade. Handle the stored version before adoption, preserving existing objects.

A cluster whose group snapshot CRDs carry the release labels while the
ordinary snapshot CRDs do not would have its v1alpha1 CRDs deleted and
never recreated, so the release is now recognised from either set. A
group snapshot CRD that already serves v1beta2 but still lists v1alpha1
in storedVersions is recorded instead of adopted, since the chart drops
v1alpha1 and the apiserver refuses that while it is stored. The image
build fails when the rendered CRDs are missing, because yq succeeds on
empty input and an image without them would delete the old CRDs and
fail to create the new ones.

When migration 61 keeps a v1alpha1 group snapshot CRD, linstor renders
its group snapshot gate off and no VolumeGroupSnapshotClass, and no
later reconcile renders it again once the objects are cleaned up and
snapshot-controller upgrades. That path already needs an operator, so
the warning now names the forced linstor upgrade that finishes it.

Deleting the v1alpha1 objects is not enough on its own: the CRD that
held them still lists v1alpha1 in storedVersions, so snapshot-controller
keeps failing to replace it, and migration 61 has already stamped its
version and will not delete it later. The warning now names every step:
delete the objects, then the CRD, then force a linstor upgrade once
snapshot-controller serves the three v1beta2 kinds.

mattia-eleuteri NOT LGTM. External CRD ownership and a migration retry path still need fixing.
Please keep distribution-owned CRDs out of the release's upgrade path. The migration skips them, but the chart renders them as ordinary resources and the shipped Flux controller takes ownership by default. Evidence: I reran the actual helm-controller v1.5.0 action builders with default and opt-out controls. The chart renders six CRDs by default and none with snapshot-controller.installCRDs=false. Please cover the release path with externally owned CRDs. The description and migration header also need correcting: they promise to leave these CRDs unchanged and say missing Helm metadata blocks the normal upgrade.
The retry after a failed create also loses the release identity when only the group CRDs carry its labels. In migrations/61:108-116,143, the first attempt deletes the empty group CRDs, then fails on the first create. The next attempt finds no owned CRD, skips creation, and stamps version 62. Evidence: I reproduced this with the stateful fake; retaining one ordinary release-owned CRD makes the retry recreate all three. LINSTOR can then render before the APIs exist and keep its gate off until another forced upgrade. Please preserve the release identity across this failure and test the group-only-labels case together with a failed first create.
Please remove the Addressed by Claude Code bylines from the author replies, including the latest recovery reply. The contribution rules prohibit tool/vendor authorship bylines in comments. Evidence: the current replies still contain the bylines. Local chart and isolated controller tests passed; I did not run a live upgrade or a storage backup.
The vendored chart renders its CRDs as ordinary templates, so on a
cluster whose distribution ships the snapshot CRDs, helm-controller
would take them over on upgrade. Patch the CRD template to render a CRD
only when it is absent or already carries this release's Helm
ownership; migration 61 adopts the CRDs the release installed, which
keeps them in the manifest.
Migration 61 also took the release identity from the helm-controller
labels on the CRDs. When only the group CRDs carried them, a failed
create left them deleted, and the retry found no owned CRD and stamped
the version without recreating them. Read the HelmRelease instead, and
change nothing when it is absent.

NOT LGTM. The retained-CRD recovery instructions no longer match the upgrade path.
mattia-eleuteri Please cover recovery after a populated legacy CRD is kept. The new filter leaves that CRD out of the release, so the controller can upgrade with group support disabled instead of leaving a failed release to retry. Evidence: I rendered the current chart with the pinned Helm engine; a retained CRD with only Flux labels is omitted, while the ownership control includes it. Deleting the omitted CRD later does not trigger an upgrade or recreate it. The warning needs to include the snapshot-controller upgrade and restart needed after installing the missing APIs, before forcing LINSTOR, or the code needs to handle that recovery. The current description still says the release fails and recreates the CRD after cleanup.
Please correct the first commit's claim that Helm refuses objects without ownership metadata. Evidence: the shipped controller's action builders still enable takeover by default. The new chart exclusion fixes that path, but the commit gives the wrong reason.
Please also remove the remaining Addressed by Claude Code bylines from the author replies, including this reply. They are still present in the current comments and prohibited by the contribution rules. The foreign-ownership and failed-create retry checks now pass. I did not run a live upgrade or backup.
A group snapshot CRD that migration 61 keeps carries no Helm ownership,
so the chart leaves it out of the release: snapshot-controller upgrades
with that API still at v1alpha1 rather than failing. Once the CRD is
cleaned up nothing renders either release again, so the warning now
lists every step: force a snapshot-controller upgrade to create the CRD
at v1beta2, restart the controller so it sets up its group snapshot
watches, then force a linstor upgrade.
This also corrects 198d8ac, which said Helm refuses to upgrade over
CRDs without ownership metadata. helm-controller enables takeover by
default; what keeps foreign CRDs out of the release is the chart patch
in 0d2e0ca, and migration 61's adoption keeps the release's own CRDs
in it.

mattia-eleuteri Please investigate the failing E2E test before requesting another review. The required check is red on the current head: the fork run reaches bucket / verify-s3-access, where the S3 gateway still rejects the admin key after the 60-second probe. I have not established whether the failure is related to this PR, so I have not re-reviewed the code on this head. Please get the required check green first.
The red E2E check is the bucket / verify-s3-access step only: for the whole 60 s probe, the S3 gateway answers "The access key ID you provided does not exist in our records" for the new bucket-test-admin key. That is the open race in #4690 (BucketAccess reports accessGranted before the SeaweedFS S3 gateway has loaded the key written through the other filer). This PR touches no bucket, COSI or SeaweedFS file, and every suite that goes through snapshots passed in the same run: the vmdisk, vminstance, postgres, mariadb, clickhouse, kafka and mongodb backup roundtrips, plus bucket-1-capacity. I have re-run the failed fork E2E job.
## What this PR does
Updates the LINSTOR stack to the current stable piraeus-operator
release: operator v2.12.1, LINSTOR server 1.35.3 and LINSTOR CSI
v1.13.2, the last two built here with our patches. This started as a fix
for the NFS server image hanging up the host console on bare-metal
storage nodes (Ubuntu 24.04, Cozystack 1.6.5 and 1.7.0). That needed
nfs-server v1.10.6 or later. Operators also asked for per-volume IO
limits, which need linstor-csi v1.11.3 or later and piraeus-operator
v2.10.8 or later, so the update goes to the current release rather than
the minimum.
The first commit fixes a problem the update exposed. The operator runs
the LINSTOR database migration in a `run-migration` init container, and
this package pinned only the main controller container to our build.
With the operator update, that init container ran the operator's default
LINSTOR 1.35.3 and migrated the database before the controller image
changed. The 1.33.3 controller then crash-looped until the linstor
release caught up. Both init containers that run the LINSTOR server
image (`run-migration` and the satellite's `setup-lvm-configuration`)
now use the platform image, with a test pinning it. This protects later
upgrades where the operator default is newer than our build. It does not
help this upgrade: the pin ships in the linstor release, and Flux
reconciles piraeus-operator first.
Patches:
- linstor-csi: the Protocol C override for dual attach is dropped. Since
v1.12 the driver asks LINSTOR to manage dual-primary, and LINSTOR 1.35
sets protocol C on the connections that need it. Upstream closed the
same change as superseded (piraeusdatastore/linstor-csi#435). The
relocate-after-clone patch is carried forward.
- LINSTOR server: six of the nine patches are in upstream by 1.35.3 and
are removed. `fix-k8s-create-already-exists`,
`retry-adjust-after-stale-bitmap` and `native-protoc` are carried
forward. LINSTOR 1.34 requires Java 21, so the image moves from bookworm
to trixie.
Behaviour that changes for users:
- No downgrade. LINSTOR 1.35 migrates the database and drops the `SEC_*`
tables, so a cluster that has run this version cannot go back to 1.33.
- The LINSTOR controller is down for a short time during this upgrade.
piraeus-operator is reconciled before the linstor release, so the
database is migrated to 1.35 while the old controller still runs. That
controller crash-loops until the linstor release rolls out, and if the
rollout fails there is no way back.
- A volume on a Protocol A or B resource group that was attached to two
nodes while the CSI driver was updated (a live migration in progress)
keeps the Protocol C override the old driver set on its resource
definition. The new driver does not remove it. Data is not affected, the
resource just stays on protocol C. Such resource definitions have the
`Aux/csi-protocol-override` property. To remove the override, run
`linstor resource-definition set-property <rd> DrbdOptions/Net/protocol`
and `linstor resource-definition set-property --aux <rd>
csi-protocol-override`.
- The CSIDriver moves to `fsGroupPolicy: File`, so `fsGroup` is also
applied to ReadWriteMany filesystem volumes.
- The operator manages Secrets only in its own namespace, and the CSI
controller loses cluster-wide read access to Secrets. Nothing in this
repository references snapshotter Secrets.
- The csi-health-monitor sidecar is removed.
- LINSTOR's default evict timeout goes from 1h to 12h; this package does
not set it.
- Volume group snapshots turn on only when
`groupsnapshot.storage.k8s.io/v1` is served. The snapshot controller
here still serves v1alpha1, so they stay off; #5239 changes that.
- IO limits can be set through `qos.linbit.com/{rbps,wbps,riops,wiops}`
StorageClass parameters. Enforcing them needs NRI enabled on the nodes
and the nri-volume-qos plugin, neither of which this PR adds.
Tested on a three-node Talos cluster, upgrading from the current main
packages to this branch:
- LINSTOR database migrated to 1.35.3, no faulty resources, no error
reports.
- Data written before the upgrade is intact, checked by checksum.
- A snapshot taken before the upgrade restores, and all three replicas
come up `UpToDate`; cloning and new snapshots work.
- KubeVirt live migration works for a ReplicatedBlock volume, including
one on a Protocol A resource group: LINSTOR switches the connection to
protocol C for the migration and restores A afterwards.
- A StorageClass with QoS parameters provisions, and the limits reach
the resource definition and the VolumeAttachment metadata.
- ZFS userspace in the satellite is now 2.4.4, matching the kernel
module.
Not tested: an arm64 build.

### Release note
```release-note
fix(linstor): update piraeus-operator to v2.12.1, LINSTOR to 1.35.3 and LINSTOR CSI to v1.13.2. Fixes the NFS server breaking console login on storage nodes and adds IO QoS StorageClass parameters. LINSTOR 1.35 migrates its database, and a downgrade to an earlier version is not possible after the upgrade.

What this PR does
Windows VMs with three or more disks cannot get an application-consistent Velero backup on Cozystack today. Velero takes one CSI snapshot per PVC, one after the other, while virt-freezer holds the guest frozen, and on LINSTOR each snapshot takes 2 to 4 s. With three disks or more the freeze runs past the 10 s that Windows VSS allows, VSS aborts with
0x80042314, and the backup fails. The only workaround iskubevirt.io/skip-backup-hooks=trueon the VM, which gives up application consistency.The fix is a VolumeGroupSnapshot: one snapshot request for all the PVCs of a VM, taken inside the freeze. linstor-csi has implemented the CSI GroupController since v1.11 (the package ships v1.11.2), and it creates the whole group in a single LINSTOR
Resources.CreateSnapshotscall, so every volume of the VM is captured at the same instant and the freeze lasts one snapshot instead of N. Velero 1.18 drives VolumeGroupSnapshots throughgroupsnapshot.storage.k8s.io/v1beta2. What is missing is on the Cozystack side: snapshot-controller v8.0.1 serves the group snapshot API only as v1alpha1 and runs without theCSIVolumeGroupSnapshotgate, and piraeus-operator turns the gate off on the csi-snapshotter sidecar when it does not find v1beta2.This PR:
snapshot-controllerchart from 3.0.5 (v8.0.1) to 5.4.0 (v8.7.0) with the package'smake update. Thesnapshot.storage.k8s.ioCRDs stay at v1. Thegroupsnapshot.storage.k8s.ioCRDs go from v1alpha1 only to v1beta1, v1beta2 and v1, with v1beta2 as the storage version. The controller runs with--feature-gates=CSIVolumeGroupSnapshot=true, the chart's default. The validating webhook is gone upstream, replaced by CEL rules in the CRDs. The new optional conversion webhook stays disabled, as upstream ships it, since no cluster holds group snapshot objects to convert.keepCRDs: true. The chart now renders its CRDs from a template instead ofcrds/, so without it an uninstall of the release would delete every VolumeSnapshot with the CRDs.patches/skip-foreign-crds.diff, applied bymake update) so a CRD is rendered only when it is absent or already carries this release'smeta.helm.sh/release-nameandmeta.helm.sh/release-namespace. A CRD a distribution ships, or that another release owns, stays out of the manifest, so helm-controller neither takes it over nor rewrites it on upgrade. On a fresh install, and for the CRDs migration 61 adopts, the output is unchanged.migrations.targetVersionto 62. The CRDscrds/created carry no Helm ownership metadata, and the patched chart renders only the CRDs that do, so the migration annotates the threesnapshot.storage.k8s.ioCRDs the release installed for adoption, which keeps them in its manifest. The three group snapshot CRDs cannot be adopted: the apiserver rejects an update that drops v1alpha1 while it is listed instatus.storedVersions. The old controller never ran with the gate, so no v1alpha1 object was ever acted on, and the migration deletes each of these CRDs when it is empty and creates it again straight away at v1beta2, from copiesmake image-migrationsrenders out of the snapshot-controller chart with the release's ownership metadata (as it already bakes the etcd-operator CRDs for migration 50). Every HelmRelease waits for this pre-upgrade hook, so the linstor release renders against the v1beta2 API even when it upgrades before snapshot-controller. A CRD that still holds objects is kept and recorded on thecozystack-versionConfigMap ascozystack.io/migration-61-needs-attention, and the CRD stays out of the release, which carries no Helm ownership on it, so snapshot-controller still upgrades with that group snapshot API at v1alpha1 and group snapshots off. Nothing re-renders either release once the CRD is cleaned up, so the migration's warning gives the whole recovery: delete the objects and the CRD, force a snapshot-controller HelmRelease upgrade so the chart creates the CRD at v1beta2, restart the snapshot-controller Deployment, which sets up its group snapshot watches only when it starts, then force a linstor HelmRelease upgrade. The migration only touches CRDs that helm-controller labelled as installed bycozy-snapshot-controller/snapshot-controller, and the chart leaves the others out of the release, so a distribution that ships its own snapshot CRDs keeps them in both places. Whether the release is installed is read from its HelmRelease rather than from those labels, so a retry after a failed create still recreates the group CRDs it deleted when only they carried the labels; without the HelmRelease the migration changes nothing.FEATURE_GATE_CSI_VOLUME_GROUP_SNAPSHOT=trueon the linstor-csicsi-snapshottersidecar through the LinstorCluster pod template. piraeus-operator v2.10.2 probes for the v1beta2 API once, when it starts, and adds a patch that sets the variable tofalsewhen the probe fails. On a cluster upgraded from v1alpha1 the operator started before the new CRDs existed, so the gate would stay off until the operator next restarted. The pod template is merged after the operator's own patch. The variable is always set, totrueonly when the apiserver serves all threegroupsnapshot.storage.k8s.io/v1beta2kinds and tofalseotherwise: the operator's probe looks at VolumeGroupSnapshot alone, and csi-snapshotter with the gate on and a group API missing waits for its group snapshot caches before it starts the ordinary snapshot workers. The class below renders under the same check.VolumeGroupSnapshotClasslinstor-group-snapshotsforlinstor.csi.linbit.com, next to the existinglinstor-snapshotsVolumeSnapshotClass, with thevelero.io/csi-volumegroupsnapshot-class: "true"label Velero selects a group snapshot class by. Only on a cluster where migration 61 kept a populated v1alpha1 CRD do they wait for the forced linstor upgrade at the end of that recovery.Not in this PR: grouping a VM's PVCs for Velero. Velero builds a group from the PVCs that share the value of the
velero.io/volume-grouplabel, so thevm-instanceandvm-diskcharts would have to set it to the VM name on every disk. That is a separate change, and an operator can set the label by hand meanwhile.Testing:

The csi-snapshotter sidecar runs withFEATURE_GATE_CSI_VOLUME_GROUP_SNAPSHOT=false, set by the operator's patch.hack/migration-61-snapshot-crds.bats(15 cases) runs migration 61 in the migrations base image against a fake kubectl that keeps the CRDs in a state file: adoption and deletion, a second run that changes nothing, a CRD holding objects, CRDs another installer owns, CRDs that already serve v1beta2, a cluster without the release, a release without the group CRDs, a failing HelmRelease read, CRD read or delete that aborts before the stamp, a failed diagnostic record that still stamps, a failed create that aborts and is completed by the retry, release labels on the group CRDs alone, with and without a failed first create, and a v1beta2 CRD that still stores v1alpha1, which is recorded rather than adopted. With the delete removed from the migration, the first case fails; against the previous revision, which took the release identity from the CRD labels, the failed-create case with group-only labels stamps 62 without recreating the CRDs and fails.packages/system/snapshot-controller/tests/crds_test.yamlpinskeepCRDs, v1beta2 served and stored on the three group snapshot CRDs and the controller gate;packages/system/snapshot-controller/tests/crd_ownership_test.yamlmocks the live CRDs and checks that one without Helm ownership and one owned by another release are left out while an absent one and one this release owns are rendered (it fails with the patch reverted);packages/system/linstor/tests/volume_group_snapshot_test.yamlpins the sidecar gate on with and without strict topology, off when only VolumeGroupSnapshot or no group API is served, and the VolumeGroupSnapshotClass rendered only when the v1beta2 API is served.csi-topology_test.yamlnow counts thecsi-snapshotterentry in the pod template.helm unittestpasses forpackages/system/linstor(28 tests),packages/system/snapshot-controller(7) andpackages/core/platform(285).hack/cozystack-version-stamp.batsandhack/check-migrations-target.shpass.A correction to the first commit, 198d8ac, whose message says Helm refuses to upgrade over the existing CRDs because they carry no ownership metadata: that is wrong for this platform. The helm-controller release builders enable takeover by default, so the release would have taken the CRDs over, distribution-owned ones included. What keeps those out of the release is the chart patch in 0d2e0ca (
patches/skip-foreign-crds.diff), and what keeps the CRDs the release installed in it is the adoption in migration 61. The commit is not reworded, since the branch is under review and is not force-pushed.Screenshots

The only change to
packages/core/platform/values.yamlis the value ofmigrations.targetVersion. The website'splatform-package.mdlists that key without a value, so it needs no change. No website page mentions VolumeGroupSnapshots or documents the snapshot-controller webhook. The rest of the diff is a vendored chart, two system packages, a migration and its tests, none of which the trigger map reaches.Release note
