Ideally, the initiator in dom0 would handle the failover of the target
successfully and domU would never know anything had happened.  I've done
things like entirely restart the target daemon without initiators
caring, but if it's gone long enough while i/o is going on, bad things
will happen.

I wouldn't pay too much attention to the ZFS fanboi's anyway.  It's does
good things but hardly anything truly useful that you can't find in LVM
and doesn't really change anything in this case.
