Constant disk activity (discuss.tchncs.de)

I am constantly hearing disc activity on my ds218+. In the Activity manager I can see constant read/write on the performance overview. In the task list I can't see anything showing read/write, other than Swap, but that shows up less frequently than i hear the clicking. The RAM usage on the system is also under 50%.

Can anyone help? I am driving myself insane, trying to find the cause. I disabled the usage history in the performance monitor and all docker containers are paused.

I would ssh into the machine and run commands like top, lsof and ps to try to figure out what is running and what files are being used.

It might be the built in media apps generating thumbnails.

This was my guess. Maybe Plex also processing removal of intros and credits too.

One of the first things I accepted on my DS918+ was, that disks will never be idle. So I packed many services (>20, most docker) on it + a raid1 M2 cache in front of the big raid5 (3x 8TB). access is quite low now and the power to spin the disks 24h per day is not wasted. DS918+ with 16GB M2-cache and its 4core CPU is a perfect thing to consolidate all those one-thing-solutions. I learned much by doing this. I still enjoy!
Next I will install 2 solar panels on balcony to supply some of the "basis power".
