Hello,

 

I am at the moment at 21% of a data rebuild on a 3TB HDD. I run 5.0.6. it is taking ages. My NAS is mounted right now.

My question is Is there a way to speed up the process?

Maybe if I take the array off-line and stop all the unnecessary running daemons in the background?

But can I do that while it is rebuilding?

 

Thanks

You can speed it up quite a bit by running the script on this page: http://lime-technology.com/forum/index.php?topic=29009.msg259087#msg259087

 

But, you're going to have to stop the rebuild to do this.  (And, I'm not 100% sure if the script requires an fully operational array).  Safest bet is to let it finish, then run the script for future parity checks / rebuilds

If you have processes or connections that are doing a lot of disk access that could certainly affect rebuild speed. If they are just mostly using CPU then it probably doesn't matter. What exactly are you referring to? Probably most things can be stopped without affecting the rebuild.

If you're doing ANYTHING that's using the disks during the rebuild, this will thrash the disks and cause everything to run a lot slower.    ... streaming a movie; writing to a disk; etc. will all have this effect.

 

If that applies here, just stop those activities -- but don't shut down the system to do so ... if you can't stop them without doing so, just wait it out and let the rebuild finish.
