I am following Approach 2: Single Slice exactly from this howto:
http://people.freebsd.org/~rse/mirror/
Everything was done up to the first reboot, and it booted into the
degraded mirror perfectly. BUT, for some reason, the mirror automatically
added the first disk without me placing a new PC MBR onto the first disk
and switching GEOM mirror to auto-synchronization and adding the first disk.
Why?
Also, why are the consumers ad0 and ad2 instead of ad0s1 and ad2s1?
So after first reboot, it is doing the syncing on its own and I get this:
