We are running vCenter Server 5.5.x and vSphere ESXi 5.5.x. On the vCenter Server, looking at the VM, it has two virtual disks - one is 25GB and one is 250GB. The "Provisioned" line is 276.11 GB which makes sense given the other files that make up the VM. The "Used Storage" line is 11.01 GB.
When I connect to that VM (Linux server), I see that it is using about 3GB from the boot disk (25GB) and its using 16GB on one partition that is on the data disk (250GB) for a total use of about 19GB.
The VMDKs are thin and the underlying LUN from the SAN array is thin also.
From vCenter's perspective, where is my missing 8GB of disk usage?
Thanks,
Dave
