Re: [Xen-users] Xen and SAN : snapshot XOR live-migration ?

AFAIK you can use the LVM volume group in all nodes, but you may not
change anything. If you need changes (e.g volume size), you must
deactivate the vg in all but one node where you actually do the change,
which in your case probably means shutting down all domU's.
Check CLVM, it is cluster-aware.
Do you mean that with cLVM you can resize a volume on the fly without
having to shut down every attached domUs (assuming the file system does
support that -- which is the case for some like XFS if I understood)?
I'm actually interested on that topic because we are about to get a SAN
for our servers.
Thanks in anticipation,
