Just a note to say this behaviour is dependant on the filesystem on
top of the LVM logical volume.... Some (most?) will require you to
take the mounted volume offline to shrink with not all allowing online
increasing of size... so it is important to double check the
documentation for your filesystem before carrying out such an exercise
whilst the volume is mounted... and of course as with any changes to
partitioning information and volumes ensure you have a backup of the
data when resizing (especially shrinking) in case of any corruption or
issues in the process....
