ReadyNas 104 - Scrubbing & Disk spindown / performance

[JohnCPun]

Hello,

I've got a ReadyNAS 104, and I've got it set up to do scrubbing once every 3 months.

However I have noticed that scrubbing takes quite a long time (it started last satuday 15-4 at 1:00, and it is now (21-4, 18:15) at 82,5%).

I do have Disk spindown set up to spindown after 15 minutes of inactivity (during weekdays during the day and during the nights all week), and I was wondering what the effect would be on the performance of scrubbing.

I was under the impression that it would only spin down the disks when they aren't active and I would think that scrubbing counts as activity, or am I seeing this incorrectly? I noticed in various other scrubbing performance topics that it was always questioned if the person having the problem had disk spindown enabled.

Anyway, for a bit of extra detail:

I've got it setup to use RAID10 with 4x 2 TB HDD (so no SSD) @ 7200 rpm

I am running firmware 6.5.1 (just noticed that there is an update available, but didn't want to interrupt the scrub)

Right now I've got just a tad over 1 TB used (2,61 of 3,63 TB free).

Thanks!

Try looking on the performance tab.  If the temperature isn't shown next to a disk drive, then that disk drive is spun down.  So if you are seeing the temperature disappear from a drive from time to time, the spindown is happening.

You can of course temporarily disable spindown, and see if the pace increases.

Thanks, that will certainly help me check what is going on 🙂
