 - **retry-secondary-after-mkfs.diff** — Retry `drbdadm secondary` after mkfs when DRBD reports the device as held open by an external probe (Talos block-controller, udev, multipathd, etc.). Without this retry, a transient `Device is held open by someone` aborts resource initialization, leaves the satellite in an intermediate state, and prevents the controller from receiving the final `UpToDate` event — orphan PVs in `Released` then cannot be cleaned up.

+- **fix-min-io-probe-device-wait.diff** — Wait for temporary probe devices before reading pool I/O properties; retry failures and fall back to a probe when ZFS volumes have no usable device path.
