lvreduce -- —Warning: reducing active logical volume to 1 GB

lvreduce— -- This may destroy your data (filesystem etc.)

lvreduce -- —do you really want to reduce “/dev/freeos/lv1”? [y/n]: y

lvreduce— -- doing automatic backup of volume group “freeos”

lvreduce— -- logical volume “/dev/freeos/lv1” successfully reduced

As you can see, barring the initial creation of the volume groups, LVM is far more extensible and easy to use than what you have been used to so far. Now you don’t need to worry about running out of disk space, thanks to LVM, and carry on working.
