Logical Volume Manager makes the dynamic expansion of file systems dead stupid simple.  However there is a weakness, if you are using a partitioned file system as your Physical Volume (PV) then you will end up needing to expand the file system if you ever need to grow the actual storage.  This can be avoided […]
