How to prevent LVM disk spinup at shutdown

[Malte Forkel <malte.forkel@berlin.de>]

Hi,

I use a couple of LVM volumes on a MD RAID1 array for backup. These volumes are rarely accessed, so I use hdparm to switch the RAID disks into standby mode.

I noticed that the disks are forced to spin up whenever the the system shuts down. What is causing the spin up? Is there a way to avoid this?

Thanks, Malte
