[OpenAFS] shared means one fs shared or many fs synchronized?

No, it does not provide transparent real-time mirroring of volumes.
There is only one RW-volume which needs to be manually synched with the
RO-clones via "vos release $volume".

You should have a RO-clone of root.afs and root.cell on every file
server. Heavily used paths which change seldomly should always have RO
clones to balance file server load and increase reliability.
