Like the title says: As soon as I turn on/wake my unRAID machine or hours later, there are constantly reads that are keeping the drives busy (not spinning down, even when forced, the just spin up again). No one is accessing the machine (except for me looking at the Web GUI ofc). For some reason, it sounds like there are accesses even when the array is stopped.

I have no idea what's going on there.

I'm afraid we have no idea either.

 

You've basically said the equivalent of:

My car is making a funny noise.  What do you think might be wrong?

 

You gave us no clues to help you figure things out.

 

Most often it is a machine on your LAN that is scanning the drives OR an add-on of plugin you've added that is constantly accessing disks.    Disconnect your LAN cable... Do the drive accesses stop?  If so, turn the machines on your lan off, one at a time?

 

Is there a parity calc/check in progress?  If so, the accesses are expected and will continue until parity is calculated.

 

Is it one disk? or all of them?  An easy way to learn what is happening is to see what files are being constantly accessed.

 

The "lsof" or "inotifywatch" commands can help there.    (You may need to install them if not already installed on your server)
