Well, obviously these are the two that are causing the problem. st0
seems to be tape drive, but this should never be mounted, as tapes are
character devices and not block devices.

You can see that those are not listed in /proc/mounts, which means the
kernel doesn't know anything about those being mounted. This means
they are only listed in /etc/mtab, maybe you might edit that file,
look for those entries and remove them, after that df -h should work
just fine.

But that won't tell us why exactly those entries ended up being added
there. Do you have any backup software that might be using the tape
drive in a strange way? Or a backup software that is configured to use
that device as a disk? Or another software (not necessarily backup
related) that is configured to use those devices? Do you really have a
tape drive on that machine?

Anyway, you might also try to reboot the machine and see if the
problem still happens or ceases to happen.

HTH,
Filipe
