Virtual Machine Disk Size Reported as -1MB or Size Unavailable (1500)
While reviewing my virtual machines using VirtualCenter, I see one or more virtual machine disks reporting a size of -1MB or Size Unavailable.
Why has this occurred?
In certain cases, the agent running on an ESX Server or GSX Server system managed by VirtualCenter is unable to poll specific virtual machine disk files for capacity information. This polling failure results in a reported disk size of -1MB or Size Unavailable.
This is harmless and in no way affects the operation of the virtual machines.
