Re: 5.0 rc2+ raid1 setup - booting off raid not working

[Carl Brewer <carl%bl.echidna.id.au@localhost>]

We've done a bit more looking into this and it appears that my problem 
manifests itself as a failure of RAID autoconfiguration.

Not sure why though ...

Symptom :

Before a reboot :

raidctl -v -C ./raid0.conf raid0


raidctl -A root raid0
raid0: Autoconfigure: Yes
raid0: Root: Yes


raidctl -s raid0
Components:
          component0: failed
           /dev/wd1a: optimal
No spares.
component0 status is: failed.  Skipping label.
Component label for /dev/wd1a:
   Row: 0, Column: 0, Num Rows: 0, Num Columns: 0
   Version: 0, Serial Number: 0, Mod Counter: 102
   Clean: No, Status: 0
   sectPerSU: 0, SUsPerPU: 0, SUsPerRU: 0
   Queue size: 0, blocksize: 0, numBlocks: 0
   RAID Level:
   Autoconfig: Yes
   Root partition: Yes
   Last configured as: raid0
Parity status: DIRTY
Reconstruction is 100% complete.
Parity Re-write is 100% complete.
Copyback is 100% complete.


raid0 is this :

START array
1 2 0

START disks
absent
/dev/wd1a

START layout
128 1 1 1

START queue
fifo 100


reboot the box and this happens (if just booting off wd0, wd1 boot fails) :
 raidctl -s raid0
raidctl: ioctl (RAIDFRAME_GET_INFO) failed: Device not configured


This shows up in /var/log/messages when the raid is configured using 
raidctl -C :

I don't think that matters though?

Any clues?
