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

[Jankowski, Chris]

Hi,

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.

Questions:

1.
Is the filesystem resource compatible with using LVM snapshots?

2.
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 ?

3.
Would either ext4 or XFS be preferable for any reasons for use with snapshots for backup?

I'd appreciate your comments.

Thanks and regards,

Chris Jankowski
