It seems the raid autoconfig does not work.
What does raidctl -vs raid0 say? An example from an older release:
raid0 Components:
/dev/wd0d: optimal
/dev/wd1d: optimal
No spares.
Component label for /dev/wd0d:

Version: 2, Serial Number: 2007050900, Mod Counter: 219
Clean: No, Status: 0

Queue size: 100, blocksize: 512, numBlocks: 153150336
RAID Level: 1
Autoconfig: Yes

Last configured as: raid0
Component label for /dev/wd1d:

Did you build your kernel with RAID autoconfig support?
