if resource is only mounted in a node, you can use ext4, xfs or any 
filesystem.
if it is mounted in more nodes simultaneously, you should use ocfs2, 
gfs2 or other cluster filesystem.

What would you do e.g. with the content of the webpages we offer ? Put them on the SAN so we don't need to synchronize them between the two nodes ? Also the database and the vm's on the SAN ? Which fs would you recommend for the SAN volumes ? OCFS2 ? Can I mount the same volume on each node contemporarily ? Or do I have to use the ocfs2 as a resource managed by pacemaker, so that the volume is only mounted if it is necessary ?
