I want to interrupt a running resync operation on an ubuntu 10.04 software raid. (This is the regular scheduled compare resync)

How to stop it while it is running? Another raid array is "resync pending", I want a complete stop of all resyncing.

[Edit: "sudo kill -9 1010" doesn't do anything, 1010 is the PID of the md2_resync process]

I would also like to know how I can control the intervals between resyncs and the remainig time till the next one.
