It's not that simple...
First you have to remember previous balance algorithm and recover it
once dumping crash dump is done.
You also have to check if dumpdev is placed somewhere on a gmirror
provider, which is not that simple, unfortunately.
Imagine your dump partition is called /dev/label/dump and there is a
long way to gmirror provider:
label/dump -> mirror/root0s1b -> mirror/root0s1 -> mirror/root0
You can't just call 'gmirror configure -b prefer /dev/label/dump'.
I'm happy to review another patch, but I don't really have any bright
idea of how this should be implemented:)
