Sun Cluster System Administration Guide for Solaris OS

Overview of Administering Cluster File Systems

No special Sun Cluster commands are necessary for cluster file system administration. Administer a cluster file system as you would any other Solaris file system, using standard 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 can also be automatically mounted at boot. Cluster file systems are only visible from the voting node in a global cluster. If you require the cluster file system data to be accessible from a non-voting node, map the data to the non-voting node with zoneadm(1M) or HAStoragePlus.

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:

SPARC: Guidelines to Support VxFS

The following VxFS features are not supported in a Sun Cluster 3.2 cluster file system. They are, however, supported in a local file system.

Cache advisories can be used, but the effect is observed on the given node only.

All other VxFS features and options that are supported in a cluster file system are supported by Sun Cluster 3.2 software. See VxFS documentation for details about VxFS options that are supported in a cluster configuration.

The following guidelines for using VxFS to create highly available cluster file systems are specific to a Sun Cluster 3.2 configuration.

The following guidelines for administering VxFS cluster file systems are not specific to Sun Cluster 3.2 software. However, the guidelines are different from the way you administer UFS cluster file systems.
