Hi Ian,

did e2fsadm display some error ?
That would explain that you didn't get more free space in the VG,
because the LV won't be reduced in that case.

I guess with 'allocated space' you mean the sum of the filesystem space.
Check with "tune2fs -l ..." what the actual filesystem sizes are
and how that fits the LV sizses (vgdisplay -v / lvdisplay -v /dev/VG/LV).
