Problems with df -mh command

[Airton Arantes]

Hello folks,

I'm getting in troubles with the df -mh command. I have two HDs, where one
is for my FreeBSD 8.2-RELEASE and other to my files sharing mounted in
/var/db/files. The command dont return anything and I can't back to shell
again, not even CTRL+C works, I think that this doesn't works because when
I do ps aux | grep df I get this:


# ps aux | grep df
root   58218  0.0  0.1  6920  1048   0- D+   Thu09AM   0:00.00 df -mh
root   92073  0.0  0.1  6920  1048   1  D+   11:18PM   0:00.00 df -mh
root   92136  0.0  0.1  9124  1228   2  S+   11:27PM   0:00.00 grep df
#

Namely, the process state is uninterruptable, so I can't to kill the
proccess.

why my command isn't doing anything?
