I'm fixing my configuration after each unexpected fencing. Probably I missed some dependency, but these messages seem somewhat unexpected to me:

Jan 11 15:54:32 h18 systemd[1]: Stopping LVM event activation on device 9:1...

Jan 11 15:54:32 h18 Raid1(prm_lockspace_raid_md10)[30659]: ERROR: Failed to set /dev/md10 readonly (rc=1)


Earlier the RA had reported:
Jan 11 15:54:31 h18 Raid1(prm_lockspace_raid_md10)[30537]: WARNING: virtlockd 4684 root   12uw  REG   9,10        0 124945 /var/lib/libvirt/lockd/lvmvolumes/6X7qr3-GXDN-zjMo-vwF2-2MeG-vftx-XzFxOb

(virtlockd.socket is enabled in systemd)
So how do you implement clusterwide virtlockd?
