I have two servers running Xen VMs. I create LVM on iSCSI target as described in http://www.howtoforge.com/xen-live-migration-of-an-lvm-based-virtual-machine-with-iscsi-on-debian-lenny. Migration works very nice, but what about snapshots? When I create a snapshot on one server, what do I need to do on the other: a) run vgscan and vgchange -ay immediately after volume creation b) run vgscan and vgchange -ay after deleting the snapshot c) nothing if I don't change anything in LVM structure on the other server while snapshot exists
