It will work fine. Use the latest version of Disk Warrior only. Most likely it won’t find anything that needs repair if you’re using your RAID for video. Having said that, I would not run it in the middle of a job/s and I would be very hesitant to run it without a backup of the RAID somewhere. I’ve never had a problem on my Xserve RAID’s with Disk Warrior, but I did loose everything twice when using Disk Warrior on my Huge Systems RAIDs (I think it was an issue with Huge and/or ATTO, but Huge tried and tried and was never able to figure out what caused the data loss).
Tony!
