The initial recovery at 11:03 was premature; vault-1's audit writes over NFS started hanging ~15 min later and the cluster regressed to 503. Full recovery required rebooting node4 (to free vault-0's stuck NFS mount and shed PVE NFS thread contention) and a second reboot of node3 (to clear another round of kernel NFS client degradation). Final recovery at 11:43:28 UTC with vault-2 as active leader on the quorum vault-0 + vault-2. vault-1 remains stuck in ContainerCreating on node2 — a third node2 reboot is required for full 3/3 quorum, but 2/3 is operationally sufficient, so that's deferred. |
