OK, thanks. So that should be fully working and correct way to do it
and I cant harm my array by this in any way?

Hello,

is it possible to cancel RAID 6 array check? echo check >
/sys/block/mdX/md/sync_action apparently only pauses it and next check
continuing from saved position. (I guess /sys/block/mdX/md/sync_min)

I want to achieve two things:

- Start check from the start of the array.

- Be sure I can shutdown array without any ill effect because check
was interrupted.

I guess that position will be cleared when array is stopped and
started again, but I dont want to guess and experiment... :)

Thanks.

Best regards,

Patrik

You'd echo idle to the sync_action to pause/stop the check. If you want
to restart from the beginning next time, just echo 0 to sync_min
(similarly, if you just want to check/repair a specific range then set
sync_min and sync_max before the check/repair).

Cheers,
    Robin
