All 3 vault voters now on proxmox-lvm-encrypted (vault-0 16:18, vault-1 + vault-2 today). The NFS fsync incompatibility identified in the 2026-04-22 raft-leader-deadlock post-mortem is no longer reachable — raft consensus log + audit log live on LUKS2 block storage with real fsync semantics. Cluster-wide consumers of the inline kubernetes_storage_class.nfs_proxmox dropped to zero after the rolling, so the resource is removed from infra/stacks/vault/main.tf. Released NFS PVs (6) remain in the cluster and will be reclaimed in Phase 3 cleanup. Lesson learned (recorded in plan): pvc-protection finalizer races the StatefulSet controller — pod recreates on the OLD PVCs unless the finalizer is patched out before pod delete. Force-finalize technique applied to vault-1 + vault-2 successfully. Closes: code-gy7h |
