i want to remove /dev/sdb from the Vg ve-daivb but it fails with the error below, so what do do now?

vgreduce ve-daivb /dev/sdb5
  Physical volume "/dev/sdb5" still in use


before vgreduce i did pvmove:

# pvmove /dev/sdb5 /dev/sda3

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.
