Created attachment 817858 [details] engine log Description of problem: The details for a storage domain include total size, free size, used size, and allocated size. The allocated size is supposed to be a sum of the virtual sizes of all the disks on the storage domain (both preallocated and thin-provision). Currently the allocated size shows the sum of the sizes of the thin provision disks' virtual sizes that have not yet been used. For example: Creating a 150 GB thin-provision disk on iscsi SD will actually use 1GB, and the allocated size will increase by 149GB, and the used size will increase by 1GB. Preallocated disks are not calculated at all in this column Version-Release number of selected component (if applicable): rhevm-3.3.0-0.28.beta1.el6ev.noarch vdsm-4.13.0-0.5.beta1.el6ev.x86_64 How reproducible: 100% Steps to Reproduce: 1. Create iscsi DC with 1 storage domain and 1 host 2. Create a thin-provision disk of 150GB 3. Create a preallocated disk of 7GB Actual results: Storage details of the domain show allocated size: 149GB Expected results: Allocated size should be 157GB (total size disks allocated) Additional info:
