To use the quorum mode "Node and file share majority", you obviously need nodes (servers), but also a share accessible by your cluster.
For this tutorial, we will create this share on our iSCSI server.
However, as long as the share is accessible by the cluster server and the server is, preferably, highly available, it will work.
Note that it's recommended that you use a cluster disk as a witness disk whenever possible. The witness share is useful only when the use of a witness disk is not possible.
For example, if the share is on another network or in another country.
In short, install the "File Server" role on the server where you want to create this witness share and go to Server Manager -> File and Storage Services -> Shares.
Click "To create a file share, start the New Share Wizard".
For this tutorial, we will create a simple "SMB Share - Quick".
Note : creating a "SMB Share - Applications" can be useful if you are creating a Hyper-V VMs cluster (for example).
Select where you want to create this share.
Enter a name for this share.
For example : witness-share.
Configure the share settings if you want.
Confirm the creation of the share.
The witness share is created.
Select "Configure a file share witness".
Specify the network path of the previously created share.
The wizard tells you that this will be a quorum : Node and File Share Majority
The share's network path used is also displayed in the summary.
As well as in the Failover Cluster Manager.
Finally, you can also configure the quorum mode to use only a witness disk.
In this case, the Quorum configuration will be : No Majority (Witness only).
To begin, select "Select the quorum witness".
Select "Do not configure a quorum witness".
Select "No Nodes" to prevent your nodes from having a vote for the quorum of your cluster.
Select your witness disk.
There will be no majority and only the witness disk will have the right to vote.
Nevertheless, as the manager will tell you, the witness disk will be a single point of failure.
Which means that this Quorum configuration should not be used. Or, make sure this disk is highly available to prevent the cluster from shutting down because the disk drive becomes inaccessible.
