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.
