If you've lost all of the data from a single partition, whilst the  
rest of AFS is working well, then this strongly points to some kind of  
systemic issue with that partition, rather than a problem with  
OpenAFS. As well as hardware failure (of the disk or of the disk  
controller), a failure of the underlying filesystem, or another  
process tampering with data on that filesystem can all cause problems  
(in particular, the OpenAFS fileserver is extremely sensitive to the  
modes of files within /vicep* being preserved). If vicepc is truly  
empty, then that would indicate some kind of catastrophic media  
failure. If vicepc contains data, but the fileserver cannot see it,  
then that would suggest that the data has been externally modified.

At this point, your best bet is probably to restore the affected  
volumes from your backups - ideally to different storage media than  
you were using before.
