HDD-Spindown with LVM

[BrummBrumm]

Hello.

I have a raid1 (linux software raid) of 2 sata-hdds and some logical volumes (LVM2) on top of that running in my desktop system.

When I run 'hdparm -Y /dev/sda /dev/sdb' to force the disks to spin down, they spin-up again a second later, but only if the lvm-service (/etc/init.d/lvm) is started - even if none of the logical volumes is used.

Is there some option to prevent LVM from spinning up my disks?


Thanks.
