I have a 3 80Gb SCSI Seagates running on an Adaptec 39160 in a G4 Quicksilver running OSX Server. I used the Disk Utility to combine them as one 210Gb volume using RAID 0.
The other day, the machine froze (I thought OSX had proper memory/process management...) and on restart I was presented with the message that I was attempting to mount disks with no readable volumes.
Oh f... thought I as there was 80Gb of work on there un-backed up as I had literally just recovered the data from the previous server that had consigned itself to bin.
Disk Utility can see the disks and can also see the RAID volume. When I ask it to verify the RAID, it says Keys Out Of Order
and that the volume needs to be repaired. After pressing the Repair button, I again get the message Keys Out Of Order
and then Repair completed
, but it clearly isn't as the volume is still missing.
I placed a call to Apple support who told me to get into Single User mode and run FSCK -Y which I have done, but that only seems to run on the ATA boot disk.
1. Can I run FSCK on the disks attached to the SCSI card?
2. If so, how do I tell Single User Mode to change to another disk?
3. Failing the above, has anyone got any ideas how to fix my RAID?
