Gpt disk not validating in failover cluster
However, when you are doing #SANLess clusters, or multisite clusters, you now have another option to consider instead of a file share witness.
Let’s look at some scenarios where a Cloud Witness would make more sense than a File Share Witness.
For example:(Conditional – if old cluster disks were not online in Step 3 or are not currently online).
In the Windows Disk Manager, bring the old cluster disks online as local disks and assign them a drive letter.
There will be a slight monthly fee for the Azure Cloud service, but this will be minimal in comparison to the cost associated with maintaining a File Share Witness.
Scenario 2 – #SANLess Hyper-V Cluster at Remote Office/Branch Office (ROBO) Here is the scenario.

Personally I will be using multiple NICs in my failover cluster configuration for network redundancy and to keep my Data Keeper replication traffic separate from my client access traffic.
It can be used instead of a disk witness or a fail share witness.
The cluster nodes simply need public internet access to reach an Azure storage account that you have provisioned as part of your Azure subscription. In most shared storage clusters you will still use a node and disk witness majority quorum.
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall.
There is no guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Before you make changes to a registry key or subkey, we recommend that you export, or make a backup copy, of the key or subkey.
