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.

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.

Hi StephenB,

" If the performance is adequate then I suggest letting it run to completion." I think, that's what I'll do.

"but 10 days sounds high." I agree. And I'd like to know, why it takes so long.

"Did you download the log zip file, and look at the SMART stats? You can see them in volume.log." Not yet. Are you talking about the attatched logfile you can access System--> logs ? Or do I have to access ReadyNas via SSH for that?

Maybe I just have a "stupid configuration" ;-)

Thanks,

Chris

  It is in the System/Logs zip file you can download using the GUI or Raidar

    Correct - There's a download link on the same page you clipped for your log png.
    
    BTW, it's best to run the maintenance functions one at a time (instead of starting a defrag a few seconds after the you started the scrub).
