- Solved
I formatted 2 disks in my Array to ZFS & those two disks will not stay spun down. (Also spins up the parity disks)
These disks are completely empty.
Docker & VM disabled
There is disk activity about once a minute.
See Screenshot, only the 2 ZFS formatted disks stay spun up.
I also have a ZFS Pool that won't stay spun down,
A single disk ZFS Pool that is empty and will not spin down
And to make it weird, an empty 6 Disk ZFS pool that does spin down.
