Disk 3 not spinning down

[bigup]

I have my disks to spin down after 30mins, docker images are on my cache, ive used open files plugin and others and cannot see any file being used on Disk 3 (sdf)

 

SMART shows drive as ok, when i manually click on spin down on this drive, nothing happens, but what is strange is, the logs for this drive are very limited and end on the 14th Jan ( the last time I rebooted the server). the other drives that spin down, all show activity each day.

 

 

ive attached diagnostics zip.

any ideas?

 

thanks!

Seems a reboot sorted this.
