Hi all

I had a major crash a few weeks ago after swapping out one of the GPU's, so I had to re-setup everything. I've noticed that none of my drives ever spin down. They are all set to default which today I set to 15 minutes. I don't understand why this is happening because they used to spin down before.

I have checked to make sure no files like docker are being accessed from the array; all shares like system etc are set to cache only. But I do have an appdata folder on disk 1 which contains the left overs from an old Plex installation which no matter what I do I can't delete. It's taking up barely anything so I haven't worked too much about it and besides the container that it was attached to is long gone. But I got thinking that coz it's the appdata share, unRAID might still be going to it, so I've been trying to delete it but I've had no luck. The closest I feel I've come is from using Midnight Commander and getting the error "Structure needs cleaning". I'm now trying to figure out how to fix this, then all the appdata files will be on the cache drive, but I'm not too hopeful that this will fix the spinning down issue coz this errant folder is only on disk one, so why don't all the others at least spin down? Seems really weird to me.

If someone could take a stab at my issue, I'd much appreciate it! In case it helps, the diagnostics file is below. Cheers!

Title originally has two issues; edited to one as the other I've resolved

Update: I've managed to fix the xfs file system and then delete the leftover folder, so I can't see any reason now for the drives to not be able to spin down. They are currently set to spin down after 15 minutes, so I shouldn't have to wait long.

I'm still struggling to figure out why none of my disks will spin down. Things I have done:

• Confirmed that none of the Docker containers write to the array directly.

• Checked Jellyfin and Plex aren't doing any scans of the array.

• From what I can see and understand of the File Activity plug in, no files of the array have been accessed for many hours.

• I do have a Windows VM set up which has unRAID shares mapped in Explorer, so I've shut down this VM.

My future plans to try and figure this out:

• I shut down all Docker containers 10 minutes ago. If I did miss any Docker containers that were accessing the array and were the cause of my issue, I'll know more in 5 or so minutes as the disks are set to spin down after 15 minutes.

• This is where I'm hoping for a little help, as I don't really know what to do next.

Shares on the array have been set up to enable sharing on the network, so I did think for a moment that this could be an issue; when if they weren't being accessed maybe just having the tunnel there might be enough, but I have a second unRAID server which is setup so that all its shares are setup for network sharing so all my media Docker containers can interact with them, but this doesn't stop its disks from spinning down so I can't see this being the issue.

Thoughts anyone?
