Everything looks good to me, the DD&C seems to be working well...

can you provide more information on what do you expect the result to be ?

The problem here is Total Capacity is 20.96TB

- Before apply license vSAN free capacity 6.60TB

- After applied license vSAN is still free capacity 6.60TB

Why after applied license vSAN and enable de-duplicate and compression total free 6.60TB ?

Hello Ame01

Was this cluster using dedupe before you applied the current license or did you do disk-conversion after? If it was already deduped, I am confused why you would think applying a license would change how much storage space your data is consuming. (?!)

Dear Bob,

we used dedupe then we applied the vSAN license.

you can see as below:

1.)  Before apply license Deduplication and compression overview

Used before: 20.35TB

2.)  After applied license Deduplication and compression overview

Remain Capacity: 13.25TB

Hello Ame01

You are reading that page incorrectly, it says that you had 20.35TB USED (e.g. before it was deduplicated and compressed) and now it is 13.25TB USED.

There is no issue here - please look at the screen more carefully.
