Should a sync always fix a mismatch it encounters? I have a RAID1 with 3
disks. Sometimes I need to replace one disk and after adding a replacement
disk syslog indicates "RebuildFinished event detected on md device
/dev/md/2, component device mismatches found: 256 (on raid level 1)" but
says nothing about fixing it.
cat /sys/block/md2/md/last_sync_action
recovery

Thank you,
