One disk won't spin down

[Bill_Hickman]

One of my disks (disk 5), will not spin down and spins up whenever I manually spin it down.  Can anyone take a look at my diagnostics and let me know if they see anything odd with the settings?
THanks,

Not sure why disk 5 i would have said likely to have a issue with disk1 as appdata seems to be on that disk aswell as cache.

Have you tried using the file activity plugin to see if there is something waking it up? 

 

Do you have anything running that might be trying to list directories on that disk? That activity won't get reported via file activity plugin. radarr / so *arr are typical culprits. Folder cache plugin might help with that use case

File activity doesn't show anything, oddly enough. I do have that plugin. I cleared it and then clicked refresh, but nothing appears. I only use Binhex plex docker on my server, and nothing else.  Any other thoughts?  I do appreciate the help!

Do you mean folder cache plugin? Is your plex media on that disk? Plex might be listing dir contents regularly. Does anything change if you stop plex and then manually spindown the disk?

I'm not sure how to see if plex media is on the disk. I believe the media is spread out over the array, but I may be misunderstanding this piece.  I did stop plex entirely (through the docker) and killed all the processes involving plex, but it still was spinning up the disk.  I put the spin down delay to default (which is set to 15 minutes).  Any other thoughts?  I know this will eventually kill the disk.

I just meant what disks the share mounted to plex is on. You can see from compute on shares tab

I guess then plex is not the culprit

 

You didn't say if you have tried the folder cache plugin. That solved it for me when running with most aggressive settings, at the expense of some cpu hit, but I have plenty of that to spare. Besides that, I'm out of ideas

I don't think it matters as much. For me it was mainly power consumption rather than drive lifespan. Modern hard drives are very good at spinning continuously, I have desktop grade drives that have been on raid for 8-10 years straight with no spindown and just a couple of short maintenance windows every year. Enterprise drives do even better given they are expected to do that in data centers anyway
