I don't see anything obviously wrong, but using lvextend on a new VG
isn't really necessary. I'd have used
# lvcreate -n mailbackup -l 100%VG backup
The remount action may have been triggered because of a communication
error between the host and the san. Were you sharing the iscsi target
between multiple hosts?
