If this is a namei fileserver you can have a look into the 
vicep-Partition. If you give me the number of the
RW-volume I can tell you the path where the files belonging to this 
volume can be found.

Then you can do there a "du" to find out how much of the data still exist.

If you have luck it's only the root directory of the volume which is gone.

You also should run volinfo or MR-AFS's traverser to find out which 
files and directories
are expected from meta-data view of your volume.
