You might want to give this a try if you have a spare machine available. Fedora + software raid to make a 5 odd partition RAID5 set and then kill one partition. Midway through the rebuild with a hot spare, kill another partition. I'm certain that if RAID5 loses two of it's disks at the same time, it's gone.On Nov 25, 2003, at 9:40 PM, Scott Burns wrote:

A computer with 4 - 100GB hard drives in a RAID 5 (parity) set up, 3 drives are active in the RAID 5, 1 hot spare drive, Total storage 200GB, actually a little less due to overhead. In this configuration, one of the drives in the raid fails, the hot spare becomes active, the raid rebuilds, and you replace the dead drive with a fresh drive and this drive becomes the hot spare. In this case, you can have 2 drives fail and the system can keep going.Same deal as above, what happens if a second drive fails during rebuild?
I haven't had it happen yet, but "in theory", with the setup above, it "should" continue to work, but you're really want to get another couple drives in that machine fast.
