Overview of Administering Cluster File Systems

No special Oracle Solaris Cluster commands are necessary for cluster file system administration. Administer a cluster file system as you would any other Oracle Solaris file system, using standard Oracle Solaris file system commands, such as mount and newfs. Mount cluster file systems by specifying the –g option to the mount command. Cluster file systems use UFS and can also be automatically mounted at boot. Cluster file systems are only visible from a node in a global cluster.

Note -  When the cluster file system reads files, the file system does not update the access time on those files.

Cluster File System Restrictions

The following restrictions apply to the cluster file system administration:

  • The unlink command is not supported on directories that are not empty. For more information, see the unlink(1M) man page.

  • The lockfs -d command is not supported. Use lockfs -n as a workaround.

  • You cannot remount a cluster file system with the directio mount option added at remount time.
