Extremely High Disk Read on some disks

Featured Replies

Hello All, I'm on Unraid 6.12.4 and am experiencing a very high number of reads on one of the disks (Disk 20) that goes up about 50k reads every refresh tick (seems like every second or less). Disk 20 now has over 300 Billion reads. I never really caught this because I have lots of disks active all the time and only caught it when I ran some disk speeds and this one was all over the place so I assumed something was up with the activity. I disabled all of my VMs and Dockers and it's the only disk that is ticking up. 

 

I tried downloading the file activity plugin but it does not show me the output.

 

Does anyone have any ideas to why this is happening? I'm getting extremely slow parity checks because of it. Sub 10MB/s, mostly in the 5MB/s and that drags on for a long time on a 18TB parity.
