How important is it? The more important the data the more you should reduce the risk of a subsequent failure. If you "don't care" then we just force it back together and cross fingers. Otherwise we run tests on all the drives before trying a restore. I'd say to run these tests on each drive; as a minimum do the first test on the failed drive, more paranoia, more tests and include the non-failed drives (to ensure they don't fail during recovery): * smartctl -t short * smartctl -t long * badblocks What happened? Smoke? Are the drives faulty (what does smartctl -a tell you) Did the cables just wiggle? Is the controller broken? You probably don't know :) I would obtain replacements for the failed drives and use ddrescue to copy from the failed drive to a replacement. Then install the good drives and begin recovery. >> I can't mount the raid no more and I am missing a hard drive when i >> run ls /dev/sd? >> I have 7 drives on my raid. You say you have 7 drives and 2 are failed. And yet I see 4 drives, not 5.
