[Bug 726461] Re: sshd on lucid causes kernel panic

[Alex Harrington]

The OCFS2 filesystem is held on an OpenFiler box.

Cluster A is our live VM system with two nodes.
Cluster B is the backup system (the box in question).

Once a week, the OpenFiler box takes an LVM snapshot of the filesystem
normally used by cluster A and exports it as a new iSCSI target.
The backup server, which is the sole member of cluster B then connects
to the new iSCSI target and mounts the OCFS2 filesystem.
It then copies the VM images from inside the OCFS2 filesystem to local disk
It then unmounts the OCFS2 filesystem, disconnects from the iSCSI target.
The OpenFiler box then stops exporting the backup target, and destroys
the snapshot.

So yes, the backup server is using OCFS2 properly, but not in the
production environment cluster since we're dealing with historical
data in the snapshot.
