Hiya, I'm in the process of planning a migration of our servers from GlusterFS 1.3.9 to 2.0.1 We run a simple set-up with two machines acting as Server and Client to facilitate mirroring of data between two webservers. They have come under alot more load recently, and GlusterFS has been locking up our Apache processes in state D alot hence my desire to test v2. I have configured both servers with a config much like the below ('srv2' is replaced with 'srv1' on the other machine), and wondered if there might be any further insight from the group about improving performance and reliability in my rather simple set-up. Also, is there any reason I can't use the existing (reasonably large) / home/export directories from GlsuterFS1.3.9 for a 2.0 install? Any tips gratefully received.
