fix(kubernetes): keep NFS publish from hanging on a dead server by lexfrei · Pull Request #4791 · cozystack/cozystack

What this PR does

When the kubevirt-csi node plugin publishes an NFS volume, it first mounts the export root into an nfs-init-* temp dir to create /data and move old files into it. That temp mount was hard. If the NFS server stopped answering at that point, the publish call never returned. kubelet gives up after 2m and retries, each retry blocked the same way, and goroutines and temp dirs piled up until the server came back or the plugin restarted.

The fix does three things:

The temp root is now mounted soft with retry=0. It only does metadata work that a retried publish redoes, so an error there is harmless, and a stuck call now ends on its own once the connection to the server is declared dead. The mount the pod gets stays hard, because a soft mount can report a failed write that the server did apply.
A publish to a target path that already has one running now returns Aborted instead of starting another. This is what stops the pile-up: at most one call per target path is stuck at a time.
Moving old files into /data now checks the destination with lstat and fails the publish on any error other than a missing file. With the soft mount, the check can fail with EIO on a file that /data already holds, and a rename issued after the server comes back would replace that file. lstat keeps a user's symlink in /data that loops or dangles from failing every publish. Such a symlink counts as present and is left alone, while before this change the rename replaced a dangling one.

I kept the default retry timeouts on purpose, although the issue suggested lowering timeo and retrans. The Linux client shares one connection per server for all of that server's mounts on the node, and the first mount sets the connection's TCP timeouts. Lowering them on the temp mount would have changed the timeouts of the pods' hard mounts too. Over NFSv4, a soft RPC fails only after the connection is declared dead, so a stuck call takes minutes to end, longer than kubelet's 2m deadline. The guard keeps kubelet's retries from adding new calls during that time.

The guard works per target path, not per volume. Two pods on one node that use the same RWX volume still publish in parallel, and each pod can have at most one stuck call.

The unit tests pin the mount options on both mounts, the guard behaviour including its release after a failed publish, and the destination check: a failed check stops the move, and a symlink in /data stays in place. They use the fake mounter. I did not test against a real NFS server that went away.

Not covered here, and tracked in #4814:

If the server's TCP connection stays up while the NFS service hangs, a soft NFSv4 RPC does not time out. The guard still limits it to one stuck call per target.
Mount from mount-utils runs mount with no deadline. This predates this change, and the guard bounds it the same way.
If the target is already hard-mounted from the dead server, the check of the target at the start of a publish blocks for good. The guard keeps this to one call per target but does not end it. Unpublish is not coordinated with a publish that is still running either. Both predate this change.
A follow-up comment on the issue reported two leftovers of the bounded unmount: an orphaned umount.nfs after a timeout, and a possible stat before umount2. Both may end sooner now that the temp mount is soft, but I have not verified either.

The change is limited to the kubevirt-csi node plugin's Go code. None of the triggers in the contributing guide's map apply: no package added or renamed, no platform values, variants, release assets, ApplicationDefinition semantics or developer tooling touched.

Release note

fix(kubernetes): an NFS volume publish in tenant Kubernetes clusters no longer hangs forever when the NFS server goes away during the publish, and kubelet retries no longer pile up while a publish is stuck. The plugin's temporary mount of the export root is now soft, and a second publish to the same target path is refused while the first is still running.

Summary by CodeRabbit

Bug Fixes
- Concurrent NFS publish requests for the same target now return an Aborted error. Different targets remain available, and a target can be used again after a request finishes, including after a failed attempt.
- Migration now stops if checking a destination encounters an unexpected error. Existing destinations, including symlinks, are left in place.
- Temporary-directory creation and mount errors now identify the affected volume.
Updates
- Temporary NFS root mounts now use soft behavior with retries disabled. The final data mount remains hard.

📝 Walkthrough

Walkthrough

NodePublishVolume now rejects concurrent publishes to the same target, configures the temporary NFS root mount with soft and retry=0, and uses Lstat to check migration destinations. Unexpected destination-check errors return Internal.

Changes

NFS publish handling

Layer / File(s)	Summary
Per-target publish coordination `packages/apps/kubernetes/images/kubevirt-csi-driver/node.go`, `packages/apps/kubernetes/images/kubevirt-csi-driver/node_test.go`	NodePublishVolume tracks active publishes by target and returns `Aborted` for a concurrent publish to the same target. Tests cover different targets, release after completion, and retry after mount failure.
Temporary mount and directory setup `packages/apps/kubernetes/images/kubevirt-csi-driver/node.go`, `packages/apps/kubernetes/images/kubevirt-csi-driver/node_test.go`	The temporary root mount adds `soft` and `retry=0`. `/data` creation tolerates `fs.ErrExist`. Temporary-directory, mount, and data-directory errors include the volume ID. Tests check mount options and these error cases.
Migration destination checks `packages/apps/kubernetes/images/kubevirt-csi-driver/node.go`, `packages/apps/kubernetes/images/kubevirt-csi-driver/node_test.go`	Migration uses `Lstat` to detect existing entries, including symlinks. It returns `Internal` for lookup errors other than not-exist. Tests cover lookup errors, symlinks, and warnings when entries are skipped.

Verdict

LGTM

The three bounded-NFS changes hang together. The concurrency guard matches the CSI contract: Aborted is the right code for a pending op, and kubelet treats it as non-final and retries with backoff. No return path leaks the guard entry, and each new behaviour is pinned by a test that goes red once you revert it. CI on the head is green, and the change still passes after current main is merged in, both the Go suite and the kubernetes chart unittests. Everything below is non-blocking.

Findings

[MINOR] packages/apps/kubernetes/images/kubevirt-csi-driver/node.go:153, Stat to Lstat silently strands a legacy root file that collides with a /data symlink

[NIT] packages/apps/kubernetes/images/kubevirt-csi-driver/node.go:26, Package-level var lstat is a test seam that becomes a data race under t.Parallel

[NIT] packages/apps/kubernetes/images/kubevirt-csi-driver/node.go:134, MkdirAll on the soft temp mount can report a misleading EEXIST, and the error omits the volume id

Notes

The final /data mount stays hard with the default foreground retry (~2m) on a dead server. That is bounded and within kubelet's 2m deadline, and the per-target guard keeps retries from piling up, so it is not an indefinite hang. The residual hang cases (TCP up / service hung, a target already hard-mounted, publish/unpublish not coordinated) are scoped out and tracked in #4814. No change requested.
Hermetic review. The image was not rebuilt and not run against a live or dead NFS server; the CSI-level behaviour was reasoned and unit-verified against the fake mounter only. If you want it exercised on a cluster, cozystack-pr-test can drive it on a dev cluster.

Findings not anchored to changed lines

These reference code outside this PR's diff (unchanged files, or lines outside a hunk), so GitHub cannot render them inline.

[NIT] packages/apps/kubernetes/images/kubevirt-csi-driver/node.go:134 MkdirAll on the soft temp mount can report a misleading EEXIST, and the error omits the volume id

Now that the temp root is soft, os.MkdirAll(dataDir, 0777) is reachable with the server unreachable: Stat(dataDir) returns EIO, MkdirAll walks up to the already-existing local temp dir, Mkdir returns EEXIST, and the confirming Lstat on the mountpoint EIOs, so MkdirAll surfaces mkdir /tmp/nfs-init-...: file exists on exactly the dead-server failure this PR targets. The node operator then reads a temp-dir-already-exists message for what is really a dead server. os.Mkdir plus errors.Is(err, fs.ErrExist) would surface the real errno. Minor and cosmetic, but note this error (and its temp-mount siblings at node.go:100 and node.go:124) also omit the volume %s that the migration errors at node.go:141/156/163 carry, worth making the publish errors uniformly greppable by volume.

[MINOR] Stat to Lstat silently strands a legacy root file that collides with a /data symlink

The switch from os.Stat to lstat on the migration destination is deliberate and tested, and it does the right thing for the dangling/looping-symlink case coderabbit raised. One corner changes behaviour with no trace left: if the export root holds a legacy file f and /data already holds a symlink named f, lstat now reports the symlink as present and continue skips the migration, so f stays in the export root, which the pod never mounts. Before this change os.Stat followed a dangling symlink, hit ENOENT, and the rename moved f into /data. No data is lost (the file is still in the export root, recoverable by an admin), and the corner needs the export root written outside the pod, so it is narrow. The gap is diagnosability: this skip has no log, while the comment at node.go:138 promises the publish fails rather than hide user data. A klog.Warningf naming the volume and the skipped entry would let an operator find a stranded file. Please confirm skip-and-leave is intended over migrate-and-replace.

Yes, skipping is intended: the migration never replaces anything in /data, a symlink included. It was silent though. f76dedf logs a warning with the volume and the entry left in the export root, and a test pins it.

 var _ csi.NodeServer = &WrappedNodeService{}

+// lstat is replaced in tests: the soft temp mount's EIO cannot be produced locally.
+var lstat = os.Lstat


[NIT] Package-level var lstat is a test seam that becomes a data race under t.Parallel

var lstat = os.Lstat is swapped by a test. It is safe today (no test in the package calls t.Parallel, and the swapper uses t.Setenv, which panics under Parallel), but it is a shared mutable global read on the server's publish path, so it turns into a data race the moment any test that reaches the migration loop is marked parallel. Making it a field on WrappedNodeService defaulted to os.Lstat in main.go removes the global without changing the seam.

Fixed in f76dedf. lstat is a field on WrappedNodeService now, nil means os.Lstat, so main.go doesn't change. mkdir got the same treatment for the MkdirAll note.

The kubevirt-csi node plugin mounts the NFS export root into a temp dir to create /data and migrate old files. That mount was hard, so with the server gone the mkdir, readdir and rename calls on it never returned. kubelet gives up after 2m and retries, and every retry blocked the same way, piling up goroutines and nfs-init-* dirs. Mount the temp root soft, so its RPCs fail once the connection to the server is declared dead instead of blocking forever; it only does metadata work that a retried publish redoes. retry=0 keeps mount.nfs from retrying a failed temp mount for 2m. timeo and retrans keep their defaults, because the first mount of a server sets them for the connection the pods' mounts of it share. The volume mount the pod gets stays hard, since a soft mount can report a failed write the server applied. Over NFSv4 that soft failure takes minutes, and a stat of a target that is already hard-mounted can block for good, so a publish for a target path that already has one running now returns Aborted instead of starting another. A soft stat can fail with EIO on a file /data already holds, and a rename issued once the server is back would replace it, so the migration now fails the publish on any stat error other than a missing destination. It checks the destination with lstat, so a user's symlink in /data that loops or dangles counts as present instead of failing every publish or being replaced by the rename. The skip it makes for a destination already in /data leaves the root entry where the pod cannot see it, so it is now logged as a warning. /data is created with a plain mkdir, since with the server gone MkdirAll fails its stat on the mount point and then reports the local temp dir as already existing instead of the EIO. The temp mount errors now name the volume, like the migration errors do. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>

IvanHunters f76dedf takes all three notes. For the out-of-diff one, /data is created with a plain mkdir now, so a dead server reports EIO instead of "file exists", and the temp mount errors name the volume. The push dropped your approval, could you take another look?

IvanHunters

Verdict

LGTM

The push closes all three notes from the earlier round. Every fix carries a test that goes back to red once you revert it, the branch still passes after a merge of current main, and the head is green in CI.

Checked and correct

The migration skip now logs the volume and the entry it leaves in the export root, and a stat that fails for anything other than "not found" fails the publish rather than renaming over what it could not see (node.go:165, node.go:167). The test seam moved off a package-level var onto nil-defaulted struct fields (node.go:38), so nothing shared and mutable sits on the publish path anymore. WrappedNodeService is only ever taken by pointer, so its sync.Map never gets copied, and -race stays clean on the concurrency tests. /data is created with a plain os.Mkdir now, so a dead server surfaces its EIO instead of a masked "already exists"; the fs.ErrExist case stays the no-op it always was, and the temp-mount and temp-dir errors name the volume (node.go:145).

[Backport release-1.7] fix(kubernetes): keep NFS publish from hanging on a dead server #5017

… on a dead server (#5017) # Description Backport of #4791 to `release-1.7`.

## What this PR does Backports to `release-1.7` from `main`, picked by the rules of the [backport policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md) in merge order. A merged pull request comes as its own commits, picked with `git cherry-pick -x` so each keeps its author, message and sign-offs, and a merge commit that carries the original's merge message with a `Backported-from:` trailer naming it; a squash-merged one comes as one pick. `backport-batch verify` checks that shape. A pick listed as changed differs from the commit it came from; `git range-diff <merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A conflict or a failing check here is a [backport task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md). -

follow-up: ### Release note ```release-note fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository. fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout. fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member. fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade. fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint. fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...＠sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time. fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back. fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking. fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts. fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result. fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand. fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing. fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret. fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain. fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged. fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane. fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged. fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase. fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading. fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix. fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring. ```

## What this PR does Backports to `release-1.7` from `main`, picked by the rules of the [backport policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md) in merge order. A merged pull request comes as its own commits, picked with `git cherry-pick -x` so each keeps its author, message and sign-offs, and a merge commit that carries the original's merge message with a `Backported-from:` trailer naming it; a squash-merged one comes as one pick. `backport-batch verify` checks that shape. A pick listed as changed differs from the commit it came from; `git range-diff <merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A conflict or a failing check here is a [backport task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md). -
