Stop resync operation

Stop resync operation

[d4lamar]

Dear Developers,

I have a question for you.

I have a raid10 md array:

Is it theoretically possible to stop a running resync operation and
mark the array as clean without stopping the array ?

I do not want the resync to be respawned automatically.

Thanks and Best Regards,
d4lamar

Firstly stop the resync with:

  echo frozen > /sys/block/mdXXX/md/sync_action

Then mark the resync as complete with
  echo none > /sys/block/mdXXX/md/resync_start

then re-enable sync with

  echo idle > /sys/block/mdXXX/md/sync_action

But maybe 6 weeks was too long to wait for a reply :-(
