Do you have a /mythlibrary directory on /dev/sda2? You state that
recordings were made to this directory - the partition is only 12G in
size, and could easily fill up with a couple of recordings, on top of
the rest of the OS installation. You may need to unmount /dev/sdb2 in
case it is shadowing the /mythlibary directory on /dev/sda2.

What other non-OS directories are located on /dev/sda?

Why are you surprised with the location of /dev/sda1? At 100M it's a
typical size for /boot.

Have you updated your storage directories in mythtv-setup to reflect
the new disk setup?

Finally, check /tmp as there could be a large temporary file sitting in there.
