Scrub feature takes too long to use...
Let's talk about the scrub feature. Is anybody actually using it? I know scrubbing is slow. I expect that. I have the scrub schedule set to do it once every three months. The problem is, it is so...
Just an update:
I'm now at 2% complete, and it's been going for 4 hours. Extrapolating, that's a total of 200 hours to get to 100%. That's just not doable. 200 hours is more than a full week (8.33 days).
Is there something I can check that may be wrong with my NAS that could cause this? Looking at the output of top, I see three kworker processes, each taking just under 30% CPU. Does this seem right?
Mine started slow, and then picked up speed - so I'm not sure that you can simply extrapolate.
How much data is in the data volume?
Data volume is only at 1.85 TB (of 5.40 TB). I get that the scrub speed is going to vary. It already has changed by quite a bit (unfortunately, in the wrong direction).
I'm going to wait this one out for at least a few days, to see how far it will get. But, like I said, the last time it took two days to get to 5%. Unless the next 95% was going to go 38 times faster than the first 5%, it wasn't going to get finished in 3 days.
I guess this is why I'm posting. I'm trying to find out if my NAS is out of whack, compared to other people that scrub.

I'll start one on my RN102 (and hopefully will remember to post speed here). The RN102 is running 6.4.2 (and recently I did a factory reset, which significantly improved performance).
