I replaced the failed disk and added a new disk to the array. While it was rebuilding the new disk there was a read error on one of the "good" disks that caused the disk to be reset by the controller and the array was brought down. I can bring the array back up in degraded mode by running mdadm --assemble --force /dev/md1; however, I have been unable to build the fifth disk. I would appreciate any help. -- Chris Purves
