    This is what I see and it seems to be saying these two drives are full?

           --- Physical volume ---
           PV Name               /dev/sdc3

    Yes I use du -h often.

    I've got a lot of large files in a Downloads directory. I'm copying
    them to another drive and I hope that will free up enough space to
    carry me through for a couple of months or whenever I am ready to
    re-install the system.

    Thanks, you have been very helpful, got me pointed in the right
    direction I believe.
