I have a cluster connected to storage via Fibre Channel, with a LUN presented to the cluster and multipathing configured. I want to use it as a backup directory; what steps must I follow to make this LUN available as a directory for all servers in the cluster?
 
In my $dayjob I have FC storage, very similar like yours (including multipath), coming from off-site. ( 3-2-1 )

I use that one as a secondary independent backup destination, as a directory storage to put vzdump-based backups on it. Limiting myself to this simple use case (no active VM container files or anything else) I just run a rack-local NFS server on top of that LUN. This NFS server runs on an isolated "backup"-VLAN with non-routed IP addresses.

To me that looked like the simplest approach and... it works fine for me :-)
