Is your /dev/mapper/emurlahn-root a symlink to some /dev/dm-X device?
If so you need to run `update-initramfs -c -t -k all' and if you don't
want to reboot also `echo change > /sys/block/dm-X/uevent'
Replace X of course with the right number.

If this isn't the case and this is really ext3 and not btrfs then I
don't know :(
