We have configured thin luns in scaleIO and our scaleIO usage is above 80% .We ran "esxcli unmap" command to recover space and recovered few TBs but still the utilization is higher than we have expected . We ran OS commands to get file system utilization on all severs but total utilization via this is very less as compared usage shown at scaleio level .

Is it because thin provisioing is not working as expected as ideally scaleio usage should be more or less same as total OS level utilization as we are doing thin provisioing ?

Please help or suggest what shall we do to recover the space .As of now we are gettting thin provisioing savings and the luns are behaving as .

Our ESXi version is 6.0

Scaleio version is 2.0.-13000.211
