hdds not part of the array but in the same chassis have not spun down.

[pras1011]

I have 10 hdds part of the array and I have 5 hdds that are not. They are all in the same chassis as I want to keep them together.

 

After the 10 hdds have spun down, every now and then I hear a very quiet hdd type noise which only lasts a few seconds. I disconnected all of the fans and I can here some spinning type noise. I then power down and pull out the 5 unused hdds and then check for noise after the 10 hdds have spun down. No noise!

 

Is there a way of spinning the 5 hdds down?

Yes. You can manually issue a spindown command using hdparm assuming your controller and drives support it. Use your appropriate drives in place of /dev/sd# below.

 

To sleep your drive:

hdparm -Y /dev/sd#

 

To check the current power mode:

hdparm -C /dev/sd#

I think that worked but what does this syslog mean?
