Dear OCFS2 Experts, I required expert comments on my below scenario. . Oracle RAC Database 11gR2 is running on RHEL5.3 (OS Kernel Version is 128). Database is in Production. We have used SAN for cluster file system and all shared partition formatted with OCFS2 Version 128. As of now, it seems to be fine. No issues received as of now. . We have business requirements. Upper managements wants to Upgrade Linux OS. (Suggested Version is RHEL 5.5). Now I want to know How should I go for above requirements. . Should I upgrade OS First or should I first Install OCFS2 RPM compatible with 5.5 Kernel ? . Any impact on my existing storage ? I need expert comments because I have not done such upgrade with OCFS2. Regards, Yuvrajsinh Chauhan || CRESTEL || Sr. DBA Elitecore Technologies Pvt.

[Ocfs2-users] Need Expert Comments - OS Upgrade
First of all, why bother update to 5.5, when you can update to 5.8? Many bugs have been fixed since 5.5. Do you really want to run into those? OCFS2 and the kernel have to be upgraded at the same time. In other words, you have to make sure you install both the kernel and the OCFS2 module that goes with it at the same time, then you reboot into the new kernel with the new OCFS2 module. The easiest thing to do is to just run yum update, and let it update to the latest package versions, and then install the OCFS2 package for the kernel that got installed. Thanks, Herbert.

Thanks Herbert for your reply. Few concern: . My shared partition is formatted with OCFS2 (128). Now if I update Linux with may be 5.5 or 5.8, no need to format all partition again right ? Because all my production data resides in that storage. . One more silly question: Can I upgrade OS one by one ? I mean first I upgrade one node and then second ?. During first node upgrade, I un-mount all shared partition and made available only to second node. I can do similar activity vice-versa ?
