Length of Scrub Maintenance
Hi Folks,
I know that question was asked at least one time before. But I did not find a suitable answer for that.
I started scrubbing my HDDs on May1st. Now, May 5th 51% are done. Thus itll be done in another five days.... Thats quite a while, I think.
Is there a way of speeding things up? Like priorization of that task(s) adding RAM or re run scrub more often?
Ok, I know the RN102 is not a very high performance NAS. Would speed (for that task improve when I repace it with a RN3xx? Actually I am happy with the 102...
Thanks in advance,
Chris
ps: Yes, the latest firmware is installed and one user in "online" plus one ISCASI connection is in use
It could be related to the quota, so if you can live without that try disabling it.
You can also clear the quota on the volume, not just the share. That will reduce the space information you see on the share page in the web ui.
The log you're looking at just reports the higher-level summary on the scrub - it doesn't show the two steps separately. I've never needed to see those details, so I don't know where they'd be logged. You could look in system.log and kernel.log.

What capacity disks do you have installed?
Also have you checked their health lately?

If the performance is adequate then I suggest letting it run to completion.
A scrub takes about 40 hours on my RN526 with 4x6TB. It scales with raw disk size, so I'd estimate about 13 hours for 2x4TB. An RN100 series will of course be slower, but 10 days sounds high.
Did you download the log zip file, and look at the SMART stats? You can see them in volume.log.
