How to check what is using my hdd?

I am running an unraid server where I also am running my dayly windows vm. My vm is running from an nvme drive used for cache but I am getting annoyed hearing constant read/writes to my mechanical hdd array. 

I firstly thought that it was plex/rutorrent that was constantly using my disks but even after shutting down those dockers I still see that the disks are being used.

I have 3x12TB drives in an array where one of them is used for parity. If I look under "main" I can see that the read/write speed constantly fluctuates between ~30KB/s and 15MB/s. I tried installing netdata and can see that something is accessing the disk frequently but can't understand what it is.

 

How can I reveal what kind of process is using the disk ?
