[OpenAFS] Volume space "lost in space".

[Anders Magnusson]

We have encountered a strange error here on a volume.  vos examine (or 
fs lq) says that it is 15G in size,
but du can only find 4G in the volume.  salvager do not find anything 
wrong with the volume.

Any hints?  The fileserver runs 1.4.5 (on RHEL4).  Reading the RELNOTES 
for the later releases
shows nothing about a fix for this problem.
