## 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.
