RESTAPI Used:

[cluster2/api/storage/cluster?fields=*]

AND

[cluster2/api/storage/aggregates?fields=space,space.block_storage.inactive_user_data,*]

 

ONTAP CLI Used:

cluster2::*> storage aggregate show-efficiency -aggregate aggr1_cluster2_01 -fields aggregate,total-logical-used,total-physical-used,aggr-logical-used,aggr-physical-used,total-storage-efficiency-ratio

AND

cluster2::*> df -A

Calculation:

OCSM Screenshot Shows Above:
7.32 MB
28.32 GB

How it get calculated:

----------------------------------------------------------------

7.32 MB derived from RestApi:

[cluster2/api/storage/cluster?fields=*]

<snip>
{
"efficiency": {
    "savings": 0,
    "ratio": 1,
    "logical_used": 7671808  <<<<----
},

</snip>

Logical_used: 7671808 == 7671808/1024/1024 == 7.32 MB

7.32 MB derived from Cluster CLI:

cluster2::*> storage aggregate show-efficiency -aggregate aggr1_cluster2_01 -fields aggregate,total-logical-used,total-physical-used,aggr-logical-used,aggr-physical-used,total-storage-efficiency-ratio

aggregate                 total-logical-used     total-physical-used     total-storage-efficiency-ratio     aggr-logical-used     aggr-physical-used
