I am trying to create a cluster file system shared by two devices. I am seeing the following error:

mkfs.ocfs2 successful

mount.ocfs2: Cluster name is invalid while trying to join the group
 Stopping ocfs2 and o2cb on device side:
Warning: Permanently added '11.1.1.2' (ECDSA) to the list of known hosts.
Stopping o2cb (via systemctl): o2cb.service.
Unmounting ocfs2_dlmfs filesystem: OK
 Copying cluster.conf to device:

The problem "mount.ocfs2: Cluster name is invalid while trying to join the group" is fixed when you use the next command:

o2cb register-cluster ocfs2

I hope this helps you.
