Oracle Clusterware 11g Release 2 (11.2) – Using standard NFS to support a third voting file for extended cluster configurations

One of the most critical files for Oracle Clusterware are the voting files. With Oracle Clusterware 11g Release 2, a cluster can have multiple (up to 15) voting files to provide redundancy protection from file and storage failures.

The voting file is a small file (500 MB max.) used internally by Oracle Clusterware to resolve split brain scenarios. It can reside on a supported SAN or NAS device. In general, Oracle supports the NFS protocol only with validated and certified network file servers (http://www.oracle.com/technology/deploy/availability/htdocs/vendors_nfs.html) Oracle does not support standard NFS for any files, with the one specific exception documented in this white paper.

This white paper will give Database Administrators a guideline to setup a third voting file using standard NFS.
