Display of Host Shows 12.7TB Capacity but all 6 VMs Only use 7.2TB

Hello, The display of the raid5 (8x2TB) shows 13TB and 12,7 seem’s to be used. But there are only 6 VMs with all in all only 7.2 TB How is this possible? Now i can’t build up another VM as the isn’t enough free space

Solution: Check if the VMs have snapshots, you could also have snapshots of some backup software.
