Hello every one... In a context of really heavy load and high availability needs, I'm evaluating plan 9 to implement a fileserver grid to be used by a web server for temporary storage (session's serializations, for example). I'd like to build a Plan 9 grid exposing a unique filesystem mounted by all the web servers. Each session could be accessible from any web server instantly, but what if a fileserver in the grid break? Is there a way to mantain such a session (actually the file storing the session data) available by keeping it sincronized beetween the Plan 9 fileservers? Hoping to have been clear... Thanks for your help Giacomo
