How to verify Quorum Configuration in Win Server 2016?

Question

How to verify Quorum Configuration in Win Server 2016?

SQLRocker 126

Get-ClusterQuorum |fl

Gives

Cluster : ClusterName
QuorumResource : File Share Witness
QuorumType : Majority

I was expecting QuorumType to be 'NodeAndFileShareMajority'? Has something changed in 2016 & "majority" seen above means 'NodeAndFileShareMajority' is it?

Is there any other way to verify QuorumType in Win Server 2016?

Thanks.

Hi,

Another way to check the quorum type is within the Failover Cluster Manager:

NodeMajority is for when you have odd number of servers in an cluster, while NodeAndFileShareMajority is for when you have an even number of nodes in an cluster.

You'll find more information in the following article:

Leon - Win 2008 cluadmin GUI used to give 'Quorum Configuration' straight up (instead of 'witness' seen above). Win 2012 that got changed but the above PowerShell worked. Now the powershell also is not working in Win 2016, so my q remains.

Read Elden's reply here:

The PowerShell method or checking via the Failover Cluster GUI are the only ways of checking this.

So looks like

Get-ClusterQuorum |fl

has just started saying 'Majority' , msft needs to update their doc then -> https://learn.microsoft.com/en-us/powershell/module/failoverclusters/get-clusterquorum?view=win10-ps

Cluadmin & powershell just show 'Witness' info now, I think one way to chk could be cluster log, on a 2 node cluster with FSW shows this:

Quorum config: <QuorumConfig tag='##' set='(0 1 2)' weights='(0 1 2)'/>
Quorum targetweights: (0 1 2)

2 node with no FSW shows:
Quorum config: <QuorumConfig tag='###' set='(1 2)' weights='(2)'/>
Quorum targetweights: (1 2)

so maybe that can be used as a indicator.

Pretty much these 3 cmds do the needful:

Get-ClusterQuorum |fl
Get-Cluster |fl name, DynamicQuorum, WitnessDynamicWeight
Get-ClusterNode | ft ID, NodeName, NodeWeight, DynamicWeight, State -AutoSize

I don't recall where I put my Quorum file witness, and it appears it's impossible to find it, which should be something simple.
