[Ocfs2-users] how to do rolling upgrade the ocfs2 2 node cluster along with new kernel without application outage.
Hi ALL, I have to do rolling upgrade on two node ocfs2 cluster, patch the server one by one, with out application outage. I tested in pre-prod 2 node cluster, once the DB is stopped by DBA team, I ran "umount -at ocfs2" and then rebooted the node1, but this also rebooted the node2. could any one please suggest me the best practice for upgrading/rebooting the cluster nodes. I have to upgrade the 3 node cluster in prod ENV with out outage. Thanks Veeera. -------------- next part -------------- An HTML attachment was scrubbed...

You have to be more specific than that. Maybe best if you ping support.
