different:

resize2fs /dev/volume_group/logical_volume 319
lvresize -L -50G dev/volume_group/logical_volume
resize2fs /dev/volume_group/logical_volume

This way the first resize makes sure that the data is smaller than the first

logical volume and then logical volume is reduced and then the filesystem
is resized in the 3rd command to the exact size of the logical volume. This
way I don't have to play with trying to figure out exactly how many blocks
to
resize the volume...
