You need to trigger a full resync from hda2 to hdb2 manually. I think mdadm /dev/md0 -f /dev/hdb2 -r /dev/hdb2 -a /dev/hdb2 should do it. You must NEVER modify an underlaying device of a raid set. This will cause problems. Sincerely, Lars Marowsky-Br=E9e --=20 High Availability & Clustering ever tried. ever failed. no matter. SuSE Labs try again. fail again. fail better.
