If this is an old filesystem (with out the rsize bit [I forget what that
is called] set) and you may want to resize in the future and on-line
resizing is important to you, it may be better to recreate the
filesystem.
This is easy if you have enough free space. Create a temporary LV the
same size the current one, put a new filesystem on it (with the correct
resize option if necessary), then copy the data over using a method that
doesn't change ownership, mtime, (and possibly atime if any scripts rely
on that re cleaning out or backing up stuff). See the multi-disk HOWTO
for some options. There's tar, rsync, cp -a (?).
Once this is done and the system is running on the new filesystem and
the old is unmounted, delete the old LV and extend the new one and
resize the filesystem.
