pvmove won't start
I'm using LVM2 on kernel 2.6.12.2 and tried to perform a pvmove. Unfortunately I got the message:
mirror: Required device-mapper target(s) not detected in your kernel
I found, dm-mirror was compiled as a module, but it was not loaded. After a "modprobe dm-mirror" it seems to work now. Can someone tell me, why the module is not loaded automatically?

I don't know what the odds of getting your distro to fix it but if you have any plans to use pvmove or make snapshots I highly recommend you load dm_snapshot and dm_mirror in your initrd or build into the kernel.
I found the hard way that I couldn't boot with the snapshot even if not mounted with out these loaded.
In debian sarge I putdm_snapshotdm_mirror
in /etc/mkinitrd/modules
and ran mkinitrd.
