Just to be clear, I should be able to issue [lv|vg]change -ay on both
systems simultaneously with no LVM corruption (data integrity will be
maintained by not starting a filesystems on both nodes simultaneously)
(as long as I don't start the filesystem on both nodes).
I would use something like GFS, but this is a HA setup for Lustre
oss/mds nodes :)
