cause
the problem with the move was that LV / was mirrored
solution
optimal solution would be to remove the mirror which was on /dev/sdb5 but that would require:
Converts mirror logical volume "vg00/lvmirror1" to linear, freeing physical extents from /dev/sda: lvconvert -m0 vg00/lvmirror1 /dev/sda
but since i already typed: "lvconvert -m0 /dev/ve-daivb/root" i have to wait for pvmove ...
# lvconvert -m0 /dev/ve-daivb/root
The link /dev/ve-daivb/root_mimage_0 should had been created by udev but it was not found. Falling back to direct link creation.
The link /dev/ve-daivb/root_mimage_0 should have been removed by udev but it is still present. Falling back to direct link removal.
Logical volume root converted.
