This works. I am totally lost. /dev/vg/lv is a link to /dev/mapper/vg-lv,
so I thought it was a problem of links. However this works on raw device

So, which device should be used, there might be a very big difference
between raw and block devices? I initially thought that block devices
should be always used and /dev/vg/lv is the most short way to write it
