Standard_D4_v2 not compatible with master

This does not seem to have anything to do with MCO. The MCO does not manage disk types you provide to the cluster.

Is Standard_D4_v2 supported? Please make sure its a supported disk type. Passing to installer team to check

From the yaml of a worker Machine,

  errorMessage: 'failed to reconcile machine "tszeaz022021-cj884-worker-centralus1-k2xtt": failed to create vm tszeaz022021-cj884-worker-centralus1-k2xtt: failure sending request for machine tszeaz022021-cj884-worker-centralus1-k2xtt: cannot create vm: compute.VirtualMachinesClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="InvalidParameter" Message="Requested operation cannot be performed because the VM size Standard_D4_v2 does not support the storage account type Premium_LRS of disk ''tszeaz022021-cj884-worker-centralus1-k2xtt_OSDisk''. Consider updating the VM to a size that supports Premium storage." Target="osDisk.managedDisk.storageAccountType"'

I wonder if the PremiumIO capability determines whether the vm supports Premium_LRS disks. If so, we could add that to the validation done in the installer.

@mstaeble Thanks for finding the error.

This is the error:
FATAL failed to fetch Metadata: failed to load asset "Install Config": [controlPlane.platform.azure.osDisk.diskType: Invalid value: "Premium_LRS": PremiumIO not supported for instance type Standard_D4_v2, compute[0].platform.azure.osDisk.diskType: Invalid value: "Premium_LRS": PremiumIO not supported for instance type Standard_D4_v2]

Thank you for fixing this.

Hi Team,

While installing OCP 4.9, I encounter same error it seems issue still exists in latest OCP version.

Master nodes require PremiumIO capabilities that Standard_D4_v3 does not support. You should use another disktype that actually supports PremiumIO. This bug was created due to the fact that it takes the installer an hour to report this issue and a fix was put in place to check if the disk has PremiumIO capabilities before the cluster creation was started, drastically reducing the time to report the wrong disk configuration.
