Last September, I migrated our fileserver from AppleshareIP to OS X Server running on a Powermac G4/1.25GHz tower. I installed OS X Server on the IBM (Hitachi) 80GB drive that came with the tower. Every night, I use Retrospect to backup the Shared Items folder so if the drive would die I can revert back to last night's backup.

After running in that configuration for 5 months now, I want to move the data to a 2-drive mirrored RAID set in the same tower using Apple RAID as the software (I've never used RAID software before). So I purchased 2 Western Digital 80GB drives, installed them, and moved the original Hitachi drive to the other bay. Then I booted off an external firewire drive and used Carbon Copy Cloner to clone the Hitachi drive to the Western Digital RAID set. The cloning went fine, however when I changed the startup disk to boot off of the RAID set I get a symbol of a circle with a line through it — It can't boot off the RAID set.

Then, as a test, I decided to clone something other than OS X Server to the RAID set. So I erased the RAID set and cloned a regular installation of Mac OS X onto the RAID. I changed the startup disk and the tower booted off of the RAID just fine.

Then, I erased the RAID, went back and cloned OS X Server to the RAID once again thinking perhaps the first time was a bad clone. This time it did the same thing...no booting off the RAID set when OS X Server was the data that was cloned. Weird!

In the past, I have successfully cloned OS X Server from the Hitachi to a Western Digital 120GB single drive with no booting problem.

Any thoughts on what could be the problem?

Thanks.

I know you are running this on a PowerMac and therefore it seems appropriate to post the message here. It is incredibly unlikely that the Power Mac is the cause of your problem--as OS X client works in your stated configuration. This is an OS X Server specific issue, so I'm going to move you to the OS X forum, where you will a)get more visibility and b)get people who are expecting to see OS X Server issues.

For what it's worth, I don't have a clue why server vs. client would make a difference here.

I believe that if you boot to the non-RAIDed OS, then select the OS on the RAID set in Startup Disk it should get it booting. Otherwise, I don't recall if you can do an archive/install with X Server. I'd suggest doing a clean install if selecting the RAID set in Startup Disk.

Edit: I just realized that you said you did this already. Sorry, still a bit sleepy today, even at 1 PM...
