Thank you for pointing this out and the nice explanation.
From reading this list and other sources issuing a repair command as
follows:
"echo repair > /sys/block/md2/md/sync_action"
might be ill-advised since it's luck of the draw whether or not the
operation gets the right data instead of the bad data.
Is this correct?
For reference I have a RAID1 with 3 disks. mdadm - v3.3 - 3rd September
2013
Thank you,
Pete
