What are cvutrace.log.* files
I was looking to clear some space recently and ran across a 21G directory (<grid_infrastructure_home>/cv/log). Inside there were a lot of files like “cvutrace.log.0_20100720015347″. These files are log files related to a RAC installation. They can safely be deleted.
To stop the files from being generated is add the following at the top of the cluvfy script in the <grid_infrastructure_home>/bin directory.
