Oddly, when I "echo repair > /sys/block/md0/md/sync_action", once it finishes, it automatically starts a repair on md1 also, even though I haven't requested it. Also, if I try to stop it using "echo idle > /sys/block/md0/md/sync_action", a repair starts on md1 within a few seconds. If I stop that md1 repair immediately, sometimes it will respawn and start doing the repair again on md1. What should I be expecting here? If I start a repair on one array, is it supposed to automatically go through and do it on all arrays sharing that personality? Thanks! -Justin
