To check the activity level, view NetVault SmartDisk statistics by using either the config --show command and option — for more information, see Using the config command options — or by using the http://<localhost>:<port#>/proc/diskmanager/diskstorage/stats.stnz command in your web browser.
In the output that is displayed, review the information in the [SmartDisk:Volume] section to determine the level of activity.
The Active Operations value shows the number of NetVault SmartDisk disk-access operations occurring on the applicable volume. In the preceding example, there are four active operations on the Staging volume, /usr/smartdisk/diskmanager/stage, and the Deduplication Activity Cap is set to 4. This means that deduplication of data staged on this volume starts when the number of active operations on that volume is fewer than four.
You can set an activity cap for a volume by using the --dedupe-cap option with the config --add|--update --volume <path> command. For more information, see Extending NetVault SmartDisk Storage Pools.
