CRS Errors

            Today I was installing a Oracle cluster on 2 new machines and encountered the error in post installation though the installation was clean.

Error - CRS not installed on any of the nodes

           Strange isn't it.. I started digging, infact crsctl was very helpful in dignosing the issue.

I had checked for the OCR and Voting disks presence and if these are accessible from the user.
First error found at one of the cluster nodes the oraInst.loc was not having the correct permissions.

The correct permissions are 644 and the files should be owned by root root.

-rw-r--r-- 1 root root 63 2012-10-11 15:46 oraInst.loc

            Once I had fixed the issue again i tried to run the post checks.

./cluvfy stage -post crsinst -n rac1,rac2 -verbose

            And again the similar error for one of the node.

           I went in to check the the logs for the same, I found that at it is referring to a file in /oraInventory/ContentsXML/inventory.xml
           and it does not have the listing of one node on one of the machine and on the other CRS="true" was missing.

CRS="true"

Updated the missing NODE NAME and CRS="true"

Imagine we are on track..

But not exactly.. Again I faced a issue with CTSS Cluster Time Synchronization service.. This looks to be not fully functional and is running in observer mode. I checked in the documentation and found that it is fine.. It should be running in OBSERVER mode.

If the timegap is huge between the servers it will not allow to start the cluster most of the times.

Fix - Needed to change the time of the machines and then started the cluster.. we are good :)

on linux --

date --set "dd mon yyyy hh24:mi:ss"

Restart the CRS..
