On a heavily loaded system, I have a pair of identical drives mirrored. No problem til today when one went stale - this happens from time to time on IDE I find. No biggie, clear off the disk, start the rebuild AND... the good drive has an Input/Output error right in the middle of it. I can mount it, look at paths, etc, but I cannot get the mirroring to complete. 3 attempts all fail. So I am thinking of trying something like a DD from the partition to the other partition. I need to get as much of the data off as possible and then replace/remirror the drive. Does anyone have ideas? The data changes so fast that the backups I do have are pretty much useless :) -- Tony Holmes Ph: (416) 993-1219 Founder and Senior Systems Architect Crosswinds Internet Communications Inc.
