I'm trying to reduce a logical vol so that I can remove a HD from it.
However, I get errors with pvmove but I don't know why:

Hi,

are you absolutely sure that the other PVs have enough space available
to remove the desired one? (this bugged me everytime i had to remove a
PV)

If I'm reading it right, the source device /dev/sdb1 has 3,200 allocated
PEs and the dest device /dev/sda2 has 14,839 free PEs (all PEs being the
same size). So it appears to me that there is enough room to do the
pvmove...
