Have you looked to see where all the space on the root partition has
gone? You can use du for this, e.g.,

	cd /
	du -sh *

will give you a summary of each top directory in /. You can drill down
to find further information.

Does the copy complete successfully and are all the files you expect
in /mnt/name?

Output from a mount command or df plus the exact command you used might
be helpful.
