[OpenAFS] How the file updation process happen in AFS?

[Hartmut Reuter]

It' not the server, but the client who starts the update. The client
will send to the server only the dirty chunks, means the chunks which
have been totally or partially rewritten. After the update in the server
the other client in your example who has got a copy of the file will get
a callback-call saying: your data are invalid.
