Never mind my last email. Figured it out.
The box now boots from /dev/mirror/gm0:
klingklang# gmirror status
Name Status Components
mirror/gm0 DEGRADED ad0
So I try to add /dev/ad1 to the raid with this command:
klingklang# gmirror insert gm0 /dev/ad1
Not all disks connected.
but /dev/ad1 is there! I can prepare it with the dd command:
klingklang# dd if=/dev/zero of=/dev/ad1 bs=512 count=79
79+0 records in
79+0 records out
40448 bytes transferred in 0.019480 secs (2076387 bytes/sec)
I'm a bit confused.
