Well {pv,vg,lv}display will give you an idea to the structure of your
storage environment (drives, partitions, volumes, etc), not if the
file system is full.

One command I use frequently is "du" or disk usage. The most useful
way I've found to use it is like this:

du -h --max-depth=1

This is nice because one you know who the biggest culprits of disk
usage you can cd into the directory and then run the exact same
command again (use the up arrow to browse your history) and follow the
trail.

There's a graphical version that's more interactive as well.

You may have some weird log file or something else that was growing
out of control for some reason. Either of those methods should help
you find it.

Good luck,
Richard
