[Linux-cluster] RHEL 6 cluster filesystem resource and LVM snapshots

I am preparing a build of a RHEL 6 cluster with a filesystem resource(s) (ext4 or XFS). The customer would like to use LVM snapshots of the filesystems for tape backup. The tape backup may take a few hours after which the snapshot will be deleted.
Is the filesystem resource compatible with using LVM snapshots?
How can I reconcile the temporary existence of a snapshot with the notion of the filesystem resource, which is all about having things permanently mounted ?
Would either ext4 or XFS be preferable for any reasons for use with snapshots for backup?
I'd appreciate your comments.
Thanks and regards,
