The disk behind /var/lib/longhorn-disk4 (sde1, 2TB PERC H710P virtual disk)
failed: 54 million SCSI I/O errors and climbing at ~7,000/minute, against 3 on
every other device on the node. Its XFS filesystem hung, so five Longhorn
replica processes and the longhorn-manager blocked in uninterruptible D state
in openat and unlinkat. D-state processes cannot be killed, so they held the
node's three replica rebuild slots permanently: no new replica could start on
talos-cp-2 and every new volume there failed to attach with DeadlineExceeded.
That is what stopped the azhi database from coming up.
Removed from all three declarations so it cannot come back:
- terraform.tfvars.local.bak, longhorn_disks for talos-cp-2
- the Longhorn add-disks Job, which would otherwise re-register it
- the Job's disk-count guard, 5 -> 4, or it would fire on every run once the
disk is gone
The running cluster already has the disk fenced
(allowScheduling=false, evictionRequested=true); the replicas are evicted and
the device retired at the controller after that.
32 degraded + 3 faulted volumes from replica rebuild failures.
cp-1/cp-2 over-committed; worker-1 had 602Gi free but scheduling
disabled. Enable it with 400Gi reserved for LLM weights.
- Add worker-1 to longhorn-nodes.yaml (allowScheduling: true)
- Add worker-1 disk config to add-disks-job (storageReserved: 400Gi,
evictionRequested: false)
Fixes controlplane.tftpl's install.wipe:true (should be false, live CPs already run false) and syncs coredns Corefile back to what's actually deployed (drops an unrolled-out, stale Kong-era rewrite).
