What is Lvreduce Linux?
lvreduce allows you to reduce the size of a logical volume. Be careful when reducing a logical volume’s size, because data in the reduced part is lost!!! You should therefore ensure that any filesystem on the volume is resized before running lvreduce so that the extents that are to be removed are not in use.
