You can use 'lvresize' with an option to resize the filesystem too, or use 'fsadm' with an option to resize the LV. We felt that 'fsadm' was a more-natural approach: allow the user to resize their filesystem and automatically adjust the things underneath as necessary. Long term, we'd like it to be possible to configure a system for resizing entire device stacks both top down (fsadm) and bottom up (triggered by the appropriate Unit Attention). (The current fsadm script was written as a proof-of-concept under the constraint of just wrapping existing binaries. Of course there are cleaner ways to do it when you allow filesystem-specific code.)
