I have a production system with raid5 0.42 tool set. Disk A of a 3 disk set failed a couple of days ago on a power cycle. The array was downed successfully PRIOR to the failure, the drive simply did not spin up and appears totally dead. I've replaced the drive and done a ckraid /etc/raid5.conf --fix --suggest-failed-disk-mask 0001 which appears to have run successfully. When I attempt to mdadd -ar /dev/md0, I get the error "invalid checksum for /dev/md0" and the array is not activated. I would dearly like to recover the array intact, any suggestions to breath life into this critter would be appreciated. Michael [EMAIL PROTECTED]
