Phase 2 of the NFS-hostile migration: data + audit storageClass on
the vault helm release switches from nfs-proxmox to
proxmox-lvm-encrypted, then per-pod rolling swap (24h soak between).
vault-0 swap done. vault-1 + vault-2 still on NFS — the rolling part
is what makes this safe (raft quorum maintained by 2 healthy pods
while one is replaced).
Also restores chart-default pod securityContext fields. The previous
`statefulSet.securityContext.pod = {fsGroupChangePolicy = "..."}`
block REPLACED (not merged) the chart's defaults — fsGroup,
runAsGroup, runAsUser, runAsNonRoot were all silently dropped. NFS
exports were permissive enough to mask the missing fsGroup; ext4 LV
volume root is root:root and the vault user (UID 100) couldn't open
vault.db, CrashLoopBackOff. Fix: provide all five fields explicitly,
survives future chart bumps. vault-1 and vault-2 retained their
correct securityContext from when their pod specs were written to
etcd, before the partial customization landed — the bug only surfaces
when a pod is recreated.
Pre-flight raft snapshot saved at /tmp/vault-pre-migration-*.snap
(recovery anchor).
