If I have a RAID 10, comprising a RAID 0, /dev/md3 made up of RAID1,
/dev/md1 and RAID1, /dev/md2 and I do an:
echo repair > /sys/block/md3/md/sync_action
will this run simultaneous repairs on the the underlying RAID 1's, or
should seperate repairs be done to md1 and 2?
Thanks for any assistence.
Regards,
Richard

check/repair is pointless on raid0, as there is no redundancy.
You should run separate checks (repairs) on the underlying devices.
