Hi,
On a DRP pool I have a thin volume created with a max size of 500GB. In order to check its current usage, I'm using the Analyze tool and then I'm downloading the comprestimator report csv file. For this volume , the report shows a thin size of 290GB and a much lower compressed size (160GB). I first thought that the host didn't sent any unmap requests and the volume was only growing in size so I run a retrim on that host (it's a Windows host so I run 'Optimize-Volume -Retrim'). I then waited for a few days just to be sure that the garbage collector had enough time to run in the background and I checked again the volume actual size from a new comprestimator report. To my surprise there is the same difference between the thin_size and the compressed_size. My logic is telling me that the thin_size should be very close to the compressed_size because the volume should grow or shrink depending on the actual data usage.
Am I right or am I missing something regarding the DRP behaviour ?
Thanks.
