Hi everyone, lately we have been focusing on tuning our afs fileservers as a part of our ongoing AFS refurbishing work. Our main focus has been our email system where we store loads of Maildirs in AFS, thus generating a continuous load on both clients and fileservers. When we monitored the clients we noticed numbers of noBuffers as well as lost callbacks, hence we had a rationale for starting to look into client tuning as well as server ditto.
The client parameters which we have been focusing on are -stat, -daemons, -rxpck and -files. Judging from the Git repo the default settings for these parameters haven't been modified since 2003. Are the default values still reasonable for a vanilla system or should they be updated? Are there any drawbacks of raising the number of daemons and rxpackets all over the line of clients? We would prefer to run all clients with the same set of config, rather than having to classify them as "high load server", "medium load servers", "low load workstations" etc. Any pointers to documents or experiences of running maildirs in AFS w.r.p. performance and availability are of course welcome.
