I don't think anyone has tried using ceph as a /vicepX partition yet.
So, what you're doing is completely untested and may not work.

After a power loss and after the server is turned back on, check
/usr/afs/logs/SalvageLog or /usr/afs/logs/SalvageLog.old after the
OpenAFS fileserver comes up. If there was an issue with the volume
because of the power loss, those should report what the problems were.

If those don't report anything, it seems likely that something else
deleted the volume header file, or it was lost because of the power
loss. There's not much OpenAFS can do about that.
