I've got 2008R2 machine running off a software mirror across two drives. I'd like to break the mirror to aid in doing a backup/restore (don't get me started on the hassles of bare metal restores...)
But when I try to break the mirror (as I've done countless times before on w2k3 and w2k) I'm confronted with an error message. It complains it can't due to the volume being a system or boot plex. STFW brought up this: http://support.microsoft.com/kb/969749
Except it doesn't work. When in an elevated command prompt I still get the same error message.
So how do I break the mirror? I tried booting into safe mode and got the same error.
