What do your logs say when you try to mount cc or restart mountd and 
nfsd?   Looks like aa and bb are seperate drives.   Is cc on the same 
partition as aa or bb (it's not in your df output)?   If so, I think 
you'll need to specify it and the other on the same line in /etc/exports.

`man exports` says:

"In a mount entry, the first field(s) specify the directory path(s) 
within a server filesystem that can be mounted on by the corresponding 
client(s).  There are two forms of this specification.  The first is to 
list all mount points as absolute directory paths separated by 
whitespace.  The second is to specify the pathname of the root of the 
filesystem followed by the -alldirs flag;"

I had to put an entry like this when I wanted to update several machines 
from one set of src and ports:

/usr/src /usr/obj /usr/ports -maproot=0

So, you might need something like:

/mnt/x/bb /mnt/x/cc -ro,quiet       B
