IntroductionNFS is an abbreviation of Network File System, a
platform independent technology created by Sun Microsystems that allows
shared access to files stored on computers via an interface called the
Virtual File System (VFS) that runs on top of TCP/IP. Computers that
share files are considered NFS servers, while those that access shared
files are considered NFS clients. An individual computer can be either
an NFS server, a NFS client or both.
We can use NFS to provide shared storage for a RAC installation. In a
production environment we would expect the NFS server to be a NAS, but
for testing it can just as easily be another server, or even one of the
RAC nodes itself.
To cut costs, this articles uses one of the RAC nodes as the source
of the shared storage. Obviously, this means if that node goes down the
whole database is lost, so it's not a sensible idea to do this if you
are testing high availability. If you have access to a NAS or a third
server you can easily use that for the shared storage, making the whole
solution much more resilient. Whichever route you take, the fundamentals
of the installation are the same.
