[OpenAFS] Fault tolerance in AFS

[Craig_Everhart@transarc.com]

AFS doesn't replicate R/W data from one server to another.  You can
approximate this in various ways, either using parts of AFS (vos
dump|vos restore) or not (mirrored or dual-ported disks).  Once data is
available on a server that's up, you can use vos syncvldb to point the
clients to the new data location.  The clients will hear from the VLDB
within an hour or when the client does "fs checkb".
