OS X.3 Server Software Raid issues

[fherbert]

I have setup a software raid which seems to work fine until the machine is restarted. On restart, the machine only displays the “
No Entry” sign (Circle with line through it) and does not boot up. Only until I unplug a certain drive, does the machine start up.
I have checked diskutility and it states the RAID is then degraded but does not give me the option to rebuild it…
From the command line I have issued the following command:

osxserver:~ root# diskutil checkRAID
RAID SETS
---------

Name:           Macintosh HD
Unique ID:      Macintosh HD9303ff7980b311d9a8f2000d9332d7e6
Type:           Mirror
Status:         Degraded
Device Node:    disk2
-------------------------------------------------------------
 #      Device Node             Status
-------------------------------------------------------------
0       disk1                   OK
1       disk0                   OK
-------------------------------------------------------------

I have already tried to rebuild the array once, it rebuilt ok, but as soon as the machine was restarted, I had the same issue again…

It a G5 Tower. Just a note is that the drives are two different sizes – one is a 80GB and the other a 120GB, not sure if this may be part of the issue or not??

I’ve only seen this once before, but for me it was actually the drive interconnect board in the xserve – moving the drive to another bay allowed me to rebuild the raid, and got rid of the issues (and of course replaced that part soon after!)… So, maybe a hardware test is required?
