One more thing. The reason I can't boot on /dev/ad1s1 is probably because /dev/ad1s1a doesn't appear to be registered (hence the invalid label problem I see at the stage one boot.) # ls /dev/ad1* /dev/ad1 /dev/ad1s1 # ls /dev/mirror gm0s1 gm0s1a gm0s1b gm0s1c gm0s1d gm0s1e gm0s1f gm0s1g gm0s1h jonah# gmirror list Geom name: gm0s1 State: COMPLETE Components: 1 Balance: round-robin Slice: 4096 Flags: NOAUTOSYNC SyncID: 1 ID: 3812009587 Providers: 1.

Is that why ad1s1a isn't appearing in /dev?
