Determining if your system is using Rapid NFS or Rapid CIFS

Use this procedure to identify whether Rapid NFS or Rapid CIFS is installed and enabled on your DR Series system.

To determine if your system is using the Rapid NFS or Rapid CIFS accelerator:

In the GUI, go to the Dashboard, and then click Container Statistics.
In the Container Name drop-down list, select a NFS or CIFS container that is associated with your client.
In the Connection Configuration pane of the statistics page, locate the NFS Write Accelerator or CIFS Write Accelerator field, depending on the protocol selected.
Next to the Write Accelerator field is a value. Active indicates that the accelerator plug-in is installed and enabled. Inactive indicates that the plug-in is not installed or not working correctly.

Viewing the Rapid NFS and Rapid CIFS logs

This topic contains information about locating and reviewing Rapid NFS and Rapid CIFS event logs for troubleshooting purposes

Viewing Rapid NFS Logs

The Rapid NFS log is located at /var/log/rdnfs.log. Statistics, throughput, and the plug-in version can be seen on the client by running the ru utility on the client, as follows:

The configuration file is located /etc/oca.0/rdnfs.cfg.

Viewing Rapid CIFS Logs

If you want a high-level view of events and errors for the Rapid CIFS accelerator, open the Windows Event Log.

If you want to view more detailed event messages from Rapid CIFS, you can access a secondary log using the following Rapid CIFS utility command. The utility is located in Program Files\Quest\Rapid CIFS.

rdcifsctl.exe -collect

Monitoring performance

This procedure describes how to monitor performance by viewing Rapid NFS and Rapid CIFS usage graphs.

To monitor Rapid NFS and Rapid CIFS performance:

In the DR Series system GUI, click Dashboard > Usage. The Dashboard page is displayed.
Click the Protocols tab.
Under NFS Usage and CIFS Usage, there is an XWrite checkbox. This checkbox represents the accelerator activity.
In the desired usage graph pane, select the XWrite checkbox to view the accelerator performance over time.

If you have Rapid NFS enabled, you can use the command line to view statistics, throughput, and the plug-in version by running the ru utility on the client, as follows:

If you have Rapid CIFS enabled, you can use the command line to view aggregate statistics (even while a backup job is running) using the following command:

Uninstalling the Rapid NFS plug-in

Use the following procedure to remove the DR Rapid NFS plug-in from a Linux-based media server. After you uninstall the plug-in, Rapid NFS will be disabled and “inactive” will be shown next to NFS Write Accelerator on the NFS Connection Configuration pane on the Container Statistics page.

To uninstall the Rapid NFS plug-in on Linux:

Run the Rapid NFS plug-in installer (usually located in /opt/Quest/DR-series/RDNFS/scripts) with the -uninstall option, which uninstalls the plug-in, using the following command:
