We are currently running on 9iRAC, OCFS1, RH Linux 3 and plan to upgrade to 10gR2, OCFS2, RH Linux4 The approach is to do both upgrade in a single maintenance window as below: 9i RAC, Linux3, OCFS1 -> 9i RAC, Linux4, OCFS2 -> 10gR2 RAC, Linux4, OCFS2 Given that OCFS2 is new and recently got certified with 10gR2 (9iRAC, OCFS2 is still awaited): I appreciate if anyone who is running on 10gR2 RAC, Linux4, OCFS2 share their experiences on the known issues, pain points etc - on scalability, stability and performance impact with OCFS2. Thanks, Shiva
