[OpenAFS] Volumes lost on fileserver / vldb post fs crash

[Hartmut Reuter]

Is this a namei-fileserver? If so you could "cd" as root into the 
/vicep-partitions
and look what remained. If the fileserver doesn't report any volumes 
probably
the volume header files are gone, but not necessarily all the data in 
AFSIDat.
You may do a "du" to see what remained.

What says the SalvageLog. It should report about any volumes the salvager so
an why he deleted them.
