Availability Set domain settings default behavior
When testing deployment of an availability set with only 1 fault domain, I get the following error and deployment fails.
"Deployment to resource group '(RG name)' failed.
Additional details from the underlying API that might be helpful: At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details."
Obviously a single fault domain is a bad idea, but if it is not allowed, this should be a) explicitly documented and b) not offered as an option in the portal.
I am providing feedback on the document here.
Please update the portal behavior so that you cannot attempt to create an AV set with 1 fault domain.

Clarification: It seems it is possible to create an availability set with only 1 fault domain AND 1 update domain.
This would be meaningless as an availability set, though, so my request would be that 2 be the minimum selectable for both fault and update domains.
