I have 3 nodes cluster , and in one node I see the following error ( this cluster has no filehare witness) .

'Shutting down cluster service because two partitions have quorum'


this situation came when the 3rd node startup at last . , before that , the other two nodes seems already running .

and also the first node (startup first ) , also has the error

WARN Cluster was operating in split brain (status = 5925) at the same time.

Hello Sakuraime,

Thank you for your question and for getting in touch.

You can check some commands via PowerShell for cmdlet and other Windows PowerShell cmdlets to configure cluster quorum.

The following example changes the quorum setting on the CONTOSO-FC1 cluster to a single node majority configuration with no quorum witness.

Set-ClusterQuorum –Cluster CONTOSO-FC1 -NodeMajority

The following example changes the quorum setting on the local cluster to a majority node with witness setting. The disk resource named Cluster Disk 2 is configured as a disk witness.

Set-ClusterQuorum -NodeAndDiskMajority "Cluster Disk 2"

The following example changes the quorum setting on the local cluster to a majority node with witness setting. The file sharing resource named \\ CONTOSO-FS \ fsw is configured as a file sharing witness.

Set-ClusterQuorum -NodeAndFileShareMajority "\\fileserver\fsw"

The following example removes the quorum vote from node ContosoFCNode1 in the local cluster.

(Get-ClusterNode ContosoFCNode1).NodeWeight=0

The following example adds the quorum vote to node ContosoFCNode1 in the local cluster.

(Get-ClusterNode ContosoFCNode1).NodeWeight=1

The following example enables the DynamicQuorum property of the CONTOSO-FC1 cluster (if it was previously disabled):

(Get-Cluster CONTOSO-FC1).DynamicQuorum=1
