Failed Lease. Can't leave or join VG

One of my server nodes in the cluster crashed while part of a VG. Some time went by and one of the other nodes lost their lease. Now I have an active LV on a node but no lock for the VG of that LV:

[root@node3 ~]# lvs
  VG sbvg_drbdpool lock skipped: storage failed for sanlock leases
  Reading VG sbvg_drbdpool without a lock.

Attemping to start the lock completes immediately but has no effect:

[root@node3 ~]# /usr/sbin/vgchange --lock-start --lock-opt auto sbvg_drbdpool
  Starting locking.  Waiting until locks are ready...

Attempting to stop the locks thinking that might clear it shows this:

[root@node3 ~]# /usr/sbin/vgchange --lock-stop sbvg_drbdpool
  VG sbvg_drbdpool lock skipped: storage failed for sanlock leases
  Reading VG sbvg_drbdpool without a lock.
  VG sbvg_drbdpool stop failed: LVs must first be deactivated

Drop and force did not clear issue:

 lvmlockctl --drop sbvg_datalake
  vgchange --lock-type none --lockopt force sbvg_drbdpool
  vgchange --lock-start --lock-opt auto sbvg_drbdpool

Attempting to try it again after Node 1's issue with systemd was fix showed this:


[root@node3 ~]# /usr/sbin/vgchange --lock-start --lock-opt auto sbvg_drbdpool
  Starting locking.  Waiting until locks are ready...
[root@node3 ~]# lvs
