[OpenAFS] /dev/rd/c0do is apparently in use by the system.

[Amar P. Patel]

I entered the entry 
/dev/rd/c0d0            /vicepa                 ext2    defaults        0 2

In /etc/fstab.  When I run mkfs -v /dev/rd/c0d0, I get an error saying
/dev/rd/c0d0 is apparently in use by the system; will not make a filesystem
here!
