iscsi and geom mirror - stupid idea or not ?

[Pete French]

what would happen if I made a machine which contained a mirrored
geom pair consiting of one local driive and one drive accessed via iscsi on
a remote machine ? would this work ?

what I am considering is two such machines, geographicly distinct. one is
a 'master' and boots off the mirrored drive, the other is a slave and
has a separate boot drive which just rngs FreeBSD to make the drive inside
it into an iscsi target for the first machine. The idea here is if the first
machine is catastrphicly killed (like building falls down on it or
something) then the second one can be rebooted from the internal drive, and
will hence become the first one. It's basically a way of making a standby
machine in case of disaster.

I havent really looked at iSCSI until recently, and this is just one of
the ideas I came up with looking at the possibilities.
