Well, like I said, it's working now, but OK. In the log in the
previous message, that is precisely what I did. At the command line,
everything looked perfectly normal until I checked the status of the array,
where it showed the devices failed on all three patitions. In the log, all
it showed were the bind and unbind statements. 'No errors, no status
statements, nothing. Anyway, here is the output now that it is working:
RAID-Server:/tmp# mdadm /dev/md1 -f /dev/hda1
mdadm: set /dev/hda1 faulty in /dev/md1
RAID-Server:/tmp# mdadm /dev/md1 -r /dev/hda1
