Configure the global NFS probe settings The global NFS probe periodically checks the following on each node: • The health of the NFS Server. The probe does this by issuing a NULL RPC call to the NFS Server on the local node. • The general health of the FS Option high-availability service. The probe does this by checking for critical FS Option processes. (If the node is initializing or shutting down, the processes may not be running.) In general, if the global NFS monitor detects that the NFS Server or an FS Option process is not up on a particular node, any Virtual NFS Services active on that node will fail over to a backup. The Export Group monitors on the node with the failure will report a DOWN status and the error information. To configure the global NFS probe, select Cluster > NFS Probe Settings on the Management Console. Frequency (seconds): The interval, in seconds, at which the global NFS probe is executed. The default is 60 seconds. Timeout (seconds): The maximum amount of time that the global NFS probe will wait for an RPC call to complete. The default is 60 seconds. Disable direct read. By default, the Export Group probe does a direct IO read operation to every exported PSFS filesystem. You may want to disable this feature if the extra IO is causing problems on your system. To disable the feature, click the checkbox. When the feature is disabled, the Export Group probe will continue to check that the filesystem is mounted. To configure the probe settings from the command line, use this command: mx nfsprobe configure [--frequency ] [--timeout ] [--directRead enable|disable] To view the configuration, use this command: mx nfsprobe showconfig [--noHeaders] [--csv] HP Scalable NAS File Serving Software administration guide 185
