Why don't my disks spin down?

Hi, thanks for reading

 

I have just moved my config into a server with room for more disks, and added a parity drive. before I added the parity drive, most of the disks would spin down and only active disks would spin up, now, all of my disks are permanently spun up, and if I hit the spin down button they spin straight back up, the majority of the disks are empty and so there is no need for them to be spinning all the time

 

Any help you can provide will be hugely welcome :-)

Are you running plex and other dockers on a cache drive or are they stored on the array?

Your appdata, domains, and system shares have data on the array. Ideally those shares would only have data on cache so docker and VMs would not keep disks spinning and so docker and VM performance would not be impacted by slower parity writes.

 

Do you actually have any VMs? Doesn't look like it since there is no libvirt image mounted.

  1. Go to Settings - Docker, Disable then Delete docker image.
  2. Set your domains and system share to cache-prefer.
  3. Run mover and wait for it to complete.
  4. Post a new diagnostic.

What is the purpose of the user shares anonymized as 'H--s' and 'P--X'? They are cache-only but have files on the array.

Is your SAS controller configured for non-RAID operation? It isn't passing SMART reports or disk serial numbers so it isn't providing enough information to allow Unraid to detect disk problems.
