Issue/Introduction
When running SSP Control Plane and Worker Node VMs on vSAN, Skyline Health may report the following warning:
“VMDK is thick provisioned while vSAN policy is thin provisioned (object space reservation 0%).”
In vCenter, the VM disk appears as Thin Provisioned.
In vSAN compliance check, the VM shows as Compliant with the thin-provisioned policy (OSR=0%).
In vSAN object metadata, the disk shows as Thick Provisioned (proportionalCapacity = 100).
This mismatch causes a Skyline Health alert.
Environment
SSP 5.0
Cause
SSP platform OVA is originally deployed as thick provisioned before being converted into a template.
Resolution
There is no resolution as of now.
As this is a false-positive alert.
