Topic: Hard Disk Spindown

[Huw]

My server is idle (i.e. no connected users) for a large part of the day, I would like to spindown my hdd's (raid1) after a couple of hours of 'inactivity'.  hdparm would work but the disk array is accessed every few seconds.  Help

If your BIOS supports APM try enabled that in conjunction with hdparm -S 252.

252 sets the timeout to 21 minutes.

Obviously if there is disk access you won't be able to spin down the drive, and if the disk array is constantly accessing the drives this won't work.

I don't see a way to compromise between APM and RAID-1; the redundancy and worth of RAID-1 by far out weighs the benefits of using APM.

Hope this helped,

Thanks,  

Sorry I didn't make myself clear, what I want to know is what is accessing my array?  Then I can do hdparm stuff, it works with 5 seconds (1) but the drive spins up when accessed again.  I'm not that bothered but it seems a waste of energy to keep the drives up all the time.  I had FreeSco, this did spin down when using hdparm.
