Cluster file systems use ZFS, or UFS, and can also be automatically mounted at boot. Cluster file systems are only visible from a node in a global cluster.
For ZFS pools, the clustered property determines the accessibility of the datasets of the pool. If the pool is imported with the clustered property set to on, then all the file system datasets in that pool will be mounted globally and available from all the cluster nodes. For more information about the clustered property, see the zpool(8) man page. Normally, a ZFS pool that hosts the ZFS cluster file systems is managed by a device group which automatically sets the clustered property to on at pool import time. Hence, you do not have to set this manually.
No special Oracle Solaris Cluster commands are necessary for UFS cluster file system administration. Administer a UFS 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.
