btw. recovering from this is actually surprisingly simple, edit the
VRList line to look like,

/snapin 7f000003 2 1000004 2000004 0 0 0 0 0 0 0

Then rebuild the VRDB (volutil makevrdb) and you'll end up with a doubly
replicated volume. Once you restart your client you can perform a
recursive ls and resolve/repair any differences between the replicas.

After that you could re-create a third replica on a new server, update
the VRList and populate it by re-resolving. The intermediate step isn't
really necessary, except that it is probably easier to first make sure
that all the data on the two replicas is consistent and accessible.
