RE: [Xen-users] Xen and GFS

You are correct, if clvmd is not running, you can activate the LV on all
the nodes without the system complaining. clvm primarily tells the
system to hand the locks off to gfs, and propogates lvm updates to the
other cluster nodes. It does not, however, give you a cluster safe file
system, so don't mount an lv on all the nodes at the same time or you
risk corruption.

Could very well be.

Good luck!  :)
