How To Recreate the Oracle Clusterware Voting Disk
Recreating the Voting disk may not be as easy as written in Metalink. If you work with RAC, you know about Metalink Note 399482.1 : “How to recreate OCR/Voting disk accidentally deleted”. Of course, you back up the voting disk every time you change your RAC configuration, or on a regular basis. You probably played with the procedure and it worked just fine. Like you, I did all of that.
Yesterday, I had to recreate this precious file when it was lost a couple of hours after the whole software stack had been installed. It was, I guess, just before we would have setup our monitoring on the server that would have backed up the voting disk. When recreating the voting disk, I was amazed that the root.sh on the second node failed with the message below:
Failed to upgrade Oracle Cluster Registry configuration
But, what amazed me even more is that, despite several issues showing up on my Metalink Search with the same error, I wasn’t able to find the fix. At least nobody wanted to share one with me. However, it might frequently occur that you haven’t all nodes installed together, and it’s very likely that some of you will run into this if you are asked to recreate the Voting disk file. It happens when you haven’t installed all the nodes with the first Clusterware runInstaller command, but instead installed only some of them and then added some nodes with the addNodes.sh script.
