Scenario : To troubleshoot advanced level of OS Issues like, Server Hang, Performace issues, Application / Process crash, This tool can be used to generate “MEMORY DUMP” on Virtual Machince (VM Servers).

Advantage of This tool is “No registry changes are needed to get the server to crash.”

Could not grant the cluster access to the share – Always ON Cluster

Scenario : Error while configuring File Share Witness as Cluster Quorum Settings.
I have faced this issue, while configuring the Failover cluster for SQL Always ON nodes, There we are using File Share Witness, Share folder will be same as ” CNO Name”, Generally this shared folder will be on different data center, and provided by NAS.

Errors :
Could not grant the cluster access to the share “\\Share Name\Share Folder (CNO as share folder)”
There was an error granting the cluster access to the selected the share “\Share Name\Share Folder”
Failed to grant permission for the cluster ” Cluster Name” to access the share ” Shared Folder”
Unable to save the properties of the share “\\\\Share Name\Share Folder”
Access Denied.

Here is the sample Cluster quorum report image, while configuring the quorum settings.

Cluster Witness

Resolution :
In the Node and File Share Majority quorum model, file share provides an axtra vote to establish quorum.

The File share requires full permission (NTFS Permission) to the Cluster name (CNO, or VCO).

Open share folder properties, Security tab – Permission, Modify – Add – Give CNO name with full permission.

Now you can try configuring File Share witness for quorum, You will be able to do it successfully.
