----Error-----------
?
mount -t ocfs2 /dev/sdd1 /opt/fc-lun1
mount.ocfs2: Invalid argument while mounting /dev/sdd1 on /opt/fc-lun1. Check
'dmesg' for more information on this error.
[root at ewhpbc3bl7 tivoli]# dmesg | tail
?(9279,5):ocfs2_fill_super:854 ERROR: Unable to create per-mount debugfs root.
ocfs2: Unmounting device (8,49) on (node 255)
?
This is something to do with ocfs2 and the lun being a clone of the one already
mounted.

tunefs.ocfs2 --cloned-volume The man page has the details. Ensure you run the command only on the cloned volume.
