    A colleague wants to use Solstice disksuite as a poor man's snapshot tool by
    mirroring a RAID, writing to it all day, breaking the mirror, mounting one
    of the RAIDS, backing it up to tape, then re-syncing the mirrors.

    In other words we want to have two RAIDS..

    d0 - four disks
    d1 - four disks

    and then a mirror d2 consisting of d0 and d1.

    Unfortunately, neither the GUI nor metainit will allow us to do it. We've
    created the two RAIDs just fine, but we can't mirror them. The GUI won't do
    it and metainit says "invalid type".

    Any other ideas on how to do this? I've been thinking about rdist-ing to
    127.0.0.1.
