I have 3 drives in a thin provisioned 2 way mirror storage pool running in Windows Server 2012 Essentials. The pool has 6.36Tb of capacity and is provisioned for up to 8Tb. Manage Storage Spaces shows 4.26Tb of used space, yet the Dashboard shows 535Gb of Used Space. I can confirm the Size on Disk is 535Gb by using Explorer to check properties of the drive.
Screen shots are attached, any ideas? Should I try an optimize-volume with defrag or retrim or something?
Thanks, Jeff
