OCFS2 Mount Fails with 'Cluster name is invalid while trying to join the group' Error
in Linux
Applies to:
Oracle Cloud Infrastructure
Linux x86-64
Symptoms:
When a secondary network interface is being used for the heartbeat, the OCFS2 service does not mount the shared storage after a reboot, displaying the following error:
mount.ocfs2: Cluster name is invalid while trying to join the group
The storage mounts successfully only after manually executing ‘o2cb register-cluster cluster-name’ or restarting the o2cb service ‘sudo systemctl restart o2cb.service’. This should happen automatically without manual intervention.
Cause:
The issue occurs because the o2cb service starts before the secondary VNIC is fully initialized, requiring a manual restart of the o2cb service to mount the volume.
