Has anyone that upgraded seen that there disks won't spin down. I can manually spin them down and they stay spun down but something is causing them to spin up and then they stay up (I'm guessing mover because last night I shut off Emby as I thought it was that)

Is it just me?

Actually it looks like default spin down delay was now set to never so it shouldn't spin down, correct? I just changed it to 45 minutes and I'm hoping that fixes it.

Think I figured it out - testing fix now

Nope - that didn't seem to work...turning off dockers to check.

use lsof /mnt/disk# to see if anything is keeping it awake.

you 100% have a docker container or a plugin reading from a disk.

Actually I think it's mover keeping things open. I tried it with all dockers off and they spun down and acted normally. I added diags but when I tried lsof it just pauses and brings up a new input and shows nothing.

Do you have SAS disks? Those are known for not obeying spin down.

note that there is a long-time-known-but-never-got-fixed bug:

• when using "spindown groups", the last drive of the group never spins down

(Disabling spindown groups fixes this, but of course you also lose the feature that all drives of a group wake up together)

Yes mostly SAS disks but now it seems to work ok. .. that was f'n weird. Anyways - thanks for your help @MowMdown and @MAM59
