You're right; I should have said "LVM under GFS". (Note to self: drink coffee before answering email!) You don't have to use GFS for Clustered LVM to work, but its prety useless if you don't. Eg: you have an iSCSI block device elsewhere on the LAN, and you want a number of clients to see/use the same filesystem on-top of it, but you also want to use LVM. The assumption is that you _have_ to run GFS (or OCFS2) in this situation. This kind of Clustered LVM probably doesn't help you much with DRBD, since the block-device isn't shared as such.
