I have built a Windows 2012 R2 failover cluster in Azure using a premium file share (https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sql/virtual-machines-windows-portal-sql-create-failover-cluster-premium-file-share) and now I am having trouble configuring a file share witness for the cluster.
I created a new storage account (not premium), added a file share, and configured it to use my AAD DS domain. I am able to connect to the file share on my cluster nodes and I granted the cluster name object computer account full control on the directory I created in the share.
When I go to configure the file share witness in the cluster I just get the following error: "An error occurred getting information for the file share 'filesharewitnessname'."
Normally I would also configure the share permission to match the ntfs permission, but I am not able to from windows when I look at the folder properties. I cannot add a computer account (the cluster) to the access control (IAM) roles from my storage account.
Anyone have any ideas? Am I missing something simple here? I was able to configure a cloud witness on a Windows 2016 cluster, but Windows 2012 R2 does not have this option. I am having trouble finding relevant documentation from Microsoft about adding a file share witness to a cluster with an azure file share storage account. Thanks!
