Uli,

yes pvmove will work. Say your 4G PV is accessed via /dev/sdc1 then
you just run "pvmove /dev/sdc1" and it'll search for free space on the other
PVs to relocate data to. If your LV(s) with data allocated on /dev/sdc1 are
striped, you need to have enough space for the particular stripes on /dev/sdc1
on another PV in the VG, which doesn't have other stripes of the very same LV(s)
allocated.
