The only tool I know of that can do this is gparted, so I assume you are
using that. In this case, it has to umount the filesystem and manually
copy data from the old start of the partition to the new start. Being
interrupted in the middle leaves part of the filesystem in the wrong
place ( and which parts is unknowable ), and so it is toast. This is
one area where LVM has a significant advantage as its moves are
interruption safe and automatically resumed on the next activation of
the volume.
