SOLVED: 4 out of 9 drives will not spinn down

[rvank]

Hi All, 3 out of my 8 data drives and my parity will not auto spin down after 15 min.

 

I have rebooted the server and waited for it to settle down and for the disks 4-8 to spin down.

After that i cleared the statistics of the drives to check for reads and writes, but don't see any on any of the drives, 5 out of 8 have spun down after 15 min, 3 and the parity did not.

 

I have used the OpenFiles plugin to check for open files in /mnt/disk and found only one (/mnt/disk4/minio/.minio.sys/format.json), but that disk was spun down.

there were no open files in /mnt/user

 

Hope somebody can help me figure this out.

Found the problem.

On the disks 1-3 and the parity disk the setting for Spin down delay was set to Never ?
