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.
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".
