[Ocfs2-users] initial cluster setup

[Sunil Mushran]

/etc/ocfs.conf is used in OCFS (Release 1)
/etc/ocfs2/cluster.conf is used in OCFS2.

The two products are different.

As others have commented, OCFS2 is a shared disk clustering
file system. It requires the disks to be concurrently accessible from
all nodes in the cluster.

# echo "stats" | debugfs.ocfs2 /dev/sdX | grep UUID
For a shared disk, the UUID must match on all nodes.
