Deduplication is not running (4046910)

Deduplication appears to be disabled. This could be seen by a deduplication queue length greater then 0, but the Items Deduplicating is 0. Or if the disk space used by SmartDisk Staging pool is much larger than the Storage pool.

For deduplication to run, it needs to be enabled both on SmartDisk and in the NetVault backup Job Options. On SmartDisk the deduplication window needs to have a schedule (default is Anytime) and garbage collection must not be running.

First, ensure that the NetVault Backup backup jobs have "Enable Deduplication" checked in the Advanced Options. This is checked by default.

If deduplication is enabled in the NetVault Backup jobs, then run the following command;

(Windows) <SmartDisk_Install_path>\foundation\bin\smartdisk config --show
(Linux) <SmartDisk_Install_path>/foundation/bin/smartdisk.sh config --show

Looking at the output, check the following conditions;

1) Under the heading [Deduplication:Enable] is 'Value=FALSE' ?
Deduplication is not enabled, issue this command to enable it;

(Windows) <SmartDisk_Install_path>\foundation\bin\smartdisk config --dedupe-enable TRUE
(Linux) <SmartDisk_Install_path>/foundation/bin/smartdisk.sh config --dedupe-enable TRUE


2) Under the heading [Deduplication:Schedule] note the setting for 'Window'.
If the system time is outside the window, deduplication cannot start.
It is possible to change the window with the following command;

(Windows) <SmartDisk_Install_path>\foundation\bin\smartdisk config --dedupe-window <window_specification>
(Linux) <SmartDisk_Install_path>/foundation/bin/smartdisk.sh config --dedupe-window <window_specification>
See the SmartDisk Administrator Guide for full window specification.

3) Check for Garbage Collection activity. Run the following command.

(Windows) <SmartDisk_Install_path>\foundation\bin\smartdisk stats
(Linux) <SmartDisk_Install_path>/foundation/bin/smartdisk.sh stats

Under the heading [Dedupe:StatSubsys] check the entry csd.gc_state. If GC is idle, the state will be 'Not in GC'.
GC must be idle for deduplication to run. Investigate if GC should still be running.
