You can install a Sun QFS file system in an Oracle Solaris Cluster environment and configure the file system for high availability. The following configuration methods are available, depending on whether your file system is shared or unshared:
In a shared file system, when the Oracle Solaris Cluster software fails over, it moves the Sun QFS file system operations from the failing server to a different server. The Oracle Solaris Cluster software then moves the metadata server's operations from a failing node to another node without requiring you to issue further commands.
You can also have shared clients outside of the cluster in an Oracle Solaris Cluster environment.
An unshared Sun QFS file system configured in an Oracle Solaris Cluster environment is a highly available file system. This type of file system is configured on one node but is enabled as a highly available resource within the cluster. When the node hosting the file system fails, the Oracle Solaris Cluster software moves the file system to another node.
For more information about these configurations, see Using Sun QFS and Sun Storage Archive Manager with Oracle Solaris Cluster.
Note - Although installing a Sun QFS file system in an Oracle Solaris Cluster environment improves reliability and decreases or eliminates unplanned downtime, it does not eliminate planned downtime. In order to maintain the reliability of the file system, you might need to occasionally bring down the Sun QFS software to run the samfsck process. You must also shut down the Sun QFS software to apply software patches or updates.
