I have a Lenovo W530 running Arch with kernel 3.79 (for bumblebee) and laptop-mode is configured properly and running. It has one SSD (sdb) and one harddisk (sdb). The sdb disk has two lvm-volumes: one is storage and one is swap.
The problem is that the harddisk keeps getting polled and lsof outputs nothing regarding the lvm volumes when these are mounted. When I mount sdb2 (a NTFS partition) the hd spins down correctly; It seems to have something to do with LVM.
All worked fine (i.e. the harddisk spinned down properly) just before I removed two lvm volumes and replaced them with a single volume (lv_storage). I removed them using lvremove and added one using lvcreate.
The harddisk-activity-indication light blinks every second or so. Hdparm can spindown the harddisk (until it gets polled again).
EDIT: problem seems to be the jdb2 journaling service. IOtop reveals that the process ([jdb2/dm-1-8]) is keeping the hd awake. However I only have dm-0(lv_swap) and dm-1 (lv_filestorage) and there are no files residing on the lv_storage volume.

It isn't LVM, it is the ext4 filesystem. By default it commits the journal to disk every 5 seconds. You can correct this using the commit mount option and setting it to a longer interval. See man mount.

It isn't LVM, it is the ext4 filesystem. By default it commits the journal to disk every 5 seconds. You can correct this using the commit mount option and setting it to a longer interval. See man mount.

I would blame the filesystem first. What filesystems do you have on the hard disk? Also, if you've activated that swap area, it's likely to be used.

All of the used filesystems are ext4. The swap has been activated (which is stored on the hd). The swap doesnt keep the hd awake (mind that the system currently has 8GB). It really must have something to do with the fact that I removed two volumes, and added one. I'll edit the post for clarity

Do iotop and powertop show anything useful?
– Gilles

Never used iotop: thanks! And yes it did: jdb2 seems to be the problem. Apparently it wants to do some journalling stuff every second -> why?

Sollution found! Will post it within the hour because StackExchange wont allow my to answer my own question within 8 hours -> it had to do with jdb2 not finishing the initial build up of journals and a low commit time. Thanks for the tip on iotop!
