Re: RAID 1 Boot Volume Rebuild Puzzle

Aaah, cheers. I ran into that first article a number of times but never noticed its relevance.

Do you know if it's substantially slower to do a rebuild on the boot disk (assuming little use) than on secondary disks? Over an hour for less than 8GB as mentioned in the article seems rather high unless there's a large constant time. The other day I went ahead and rebuilt mine with the plan I mentioned before of cloning to another drive then booting from that and doing the rebuild. The rebuild there took about 1:40 for over 100GB (plus 40 minutes with the system offline to make the clone).

Thanks,

Jan

It is software RAID as created by OS X Server 10.3 (I think 10.3.4 or so). I can't find anything stating a version number for the RAID, although I hear having created it under 10.3 means it is Version 1.x. It has not been upgraded to the version (2.x?) with OS X Server 10.4. 

If it's a 10.3 RAID it is AppleRAID v.1.

Even with that you should be able to do a background rebuild without taking the volume down.
