DFS is based on the Windows Change Journal. There can be several seconds to a minute of latency before file changes replicate from one DFS server to the other. Be sure that your application could tolerate that. If I was going to try a DFS-based approach, I'd just run DFS right on the tomcat server(s). However, my experience with DFS has been unsatifactory. Replication often drives up average disk queue lengths on both servers and causes application-level freezes. Personally, I'd strongly recommend using Linux+DRBD+Pacemaker. Much faster and more stable. -- Eric Robinson Disclaimer - June 22, 2010 This email and any files transmitted with it are confidential and intended solely for Tomcat Users List.
