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.
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:
ru --mpt=[rdnfs mount point] | --pid=[process ID of rdnfs] --show=[name|version|parameters|stats|performance]
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
This procedure describes how to monitor performance by viewing Rapid NFS and Rapid CIFS usage graphs.
Before you view usage graphs, make sure that the appropriate accelerator is active by viewing the Container Statistics in the DR Series system GUI.
To monitor Rapid NFS and Rapid CIFS performance:
- In the DR Series system GUI, click Dashboard > Usage. The Dashboard page is displayed.
- In the Actions menu in the upper right corner of the page, click Detailed Graphs.
- Select a time range (if needed) and click Apply.
- 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:
ru --mpt=[rdnfs mount point] | --pid=[process ID of rdnfs] --show=[name|version|parameters|stats|performance]
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:
\Program Files\Quest\Rapid CIFS\rdcifsctl.exe stats -s
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 Statisticspage.
|
NOTE: You should retain the DR Rapid NFS plug-in installer on the media server in case you need to use it to reinstall the plug-in. It is usually located in /opt/quest/DR-series/RDNFS/scripts. |
To uninstall the Rapid NFS plug-in on Linux:
- Stop the Data Management Application (DMA) backup service before using the -uninstall option.
The Rapid NFS plug-in installer returns an error if the DMA service is running when attempting to uninstall the plug-in.
- 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:
$> ./QuestRapidNFS-xxxxx-x86_64.bin -uninstall
|
NOTE: You must stop the DMA service before uninstalling the Rapid NFS plug-in (you are also required to use the Rapid NFS plug-in installer to uninstall the plug-in). |
- Check that the plug-in is uninstalled by viewing the usage graph in the GUI; it should not indicate any XWriteactivity.
