We are thinking of upgrade RHEL 3 to RHEL4, since RHEL 3 support is going to end in 2010. Our Oracle10g 10.1.0.4.2 RAC is based on RHEL 3, OCFS1.
The problem with the upgrade is OCFS1 is only supported in RHEL3, and OCFS2 is only supported in RHEL4. What's the best plan to upgrade from RHEL 3 to RHEL 4 in this case? (I thought about removing one node from current RAC, getting rid of everything on this node, reinstall RHEL4/clusterware/Oracle software on it, then rejoin this node into the RAC, but I guess OCFS1 might not work in RHEL4, right?) One possible plan is as follows: 1. Remove one node from RAC, remove this node from all client configuration. Install RHEL4/clusterware/Oracle DB software (could be 10gR2 instead of 10gR1) on this node (with complete new sets of SAN LUNs, but same database instance/service names). Migrate/Import all Oracle DB data into this new RAC. 2. Do the same thing for some other RAC nodes, and joining them into this new RAC. 3. Pointing all RAC clients to use this new RAC. 4. Do the same thing from all remaining RAC nodes, and joining them into this new RAC. It's going to be painful, but it seems to be the only way. Any suggestions?
