Oracle Database 12 c provides the following enhancements to cluster resources for Cloud FS:
• File System Resource Enhancements
The file system resource has been enhanced through the provision of extra attributes.
The file system resource enhancements provide administrators with better control over
where file systems are mounted, what mount options are used, and whether the file
system should be mounted automatically. The full form of the srvctl add
filesystem command is shown on the slide. The new attributes include:
-nodes Comma-separated list of nodes on which the file system will be
mounted (The default is all nodes.)
-serverpools Comma-separated list of server pools on which the file system will
be mounted (The default is all server pools.)
-fstype File system type
-fsoptions Comma-separated list of file system mount options
-description File system description
-appid File system application ID
-autostart Policy for automatically starting the file system
