Have you seen the error in your logs "tsse.scan.start.failed: 'Space Reclaim Estimate Scan' failed to start on '<AGGR-NAME>; - CDE Disabled."?

This can happen when you manually start garbage collection estimate with the following commands
::> set diag
::> storage aggregate efficiency garbage-collection-estimate-reclaim start -aggregate <AGGR-NAME>

When you look at the output from the following commands
::> storage aggregate efficiency garbage-collection-estimate-reclaim show -aggregate <AGGR-NAME>

 

You get the following output

 

                                      Node: <NODE-NAME>
                            Aggregate: <AGGR-NAME>
                               Progress: IDLE
                                    Status: FAIL
                   Failure Reason: CDE Disabled
                         Total Blocks: -
Total Blockes Processed: -
                           Percentage: -


Cause: This is because "Has Auto Adaptive Compression Savings" is set to false.

 

This can be verified through the commands
::> storage aggregate efficiency show -aggregate <AGGR-NAME>

                                                                 Aggregate: <AGGR-NAME>
                                                                          Node: <NODE-NAME>

Cross Volume Background Deduplication: true
              Cross Volume Inline Deduplication: true
 Has Cross Volume Deduplication Savings: true
  Has Auto Adaptive Compression Savings: false
