I've also done them on non-startup disks as well. I definitely understanding finding that window of time to rebuild them. Fortunately Apple seems to have fixed Disk Utility so you no longer need to go and reboot your machine with the Installer disk. Just open up Disk Utility and add a new disk to the RAID set and it should automatically start rebuilding in the background (so long as you had the automatically rebuild in background button checked). Now obviously there's going to be a decrease in performance but you won't have downtime. My 500GB set took about 8-9 hours to rebuild. Hi,

To clarify, was the RAID set you rebuilt being used as the startup disk? I have a server with a degraded RAID that I need to rebuild, but trying to find the time to reboot off the install disk to do the rebuild is tough as it's our OD Master.
