+Download, build, install, and configure PVFS2.  PVFS2 can work in a
+failover environment as long as the clients and servers are version
+0.5.0 or newer (Version 0.5.0 introduced the ability to retry failed
+operations). In this document, we have configured both PVFS2 server to
+act as both a Metadata and a Data server.  Since the config files and
+storage device are shared between both nodes of this cluster, it is not
+strictly necessary to configure the servers for both roles. Create a
+storage space on the PowerVault filesystem.  Now shutdown PVFS2 and
+unmount the file system.
