OK, decided to try it.. here's what I get:
xen1:~# lvcreate -L 1G -s -n snaptest /dev/XenSystemDisks/iron
Error locking on node nitrogen: Internal lvm error, check syslog
Aborting. Failed to activate snapshot exception store. Remove new LV and
retry.
Error on Nitrogen:
Aug 2 14:09:05 nitrogen lvm[295]: Volume group for uuid not found:
doCTDCC376pE3g2JA35fNAieVNTWpAC1B3UIGOGQpn5Um5FcmPsa8yQPa0p9o9ZP
Nitrogen does not have access to the PV that this snapshot is on, which could
be part of the problem.
Shut down Nitrogen and the rest of the nodes that do not have access to
that PV, and get:
xen1:~# lvcreate -L 1G -s -n snaptest /dev/XenSystemDisks/iron
Error locking on node xen2: Internal lvm error, check syslog
Error locking on node xen1: Internal lvm error, check syslog
