Cluster node was removed from the active failover cluster membership



Below was the cluster setup where the issue came...








Error messages which logged in Cluster error log...
 

Cluster node 'ABCD-xyz05' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.


Cluster node 'ABCD-xyz04' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.

Cluster node 'ABCD-xyz03' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
 
The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk.

Cluster node 'ABCD-xyz05' failed to join the cluster because it could not communicate over the network with any other node in the cluster. Verify network connectivity and configuration of any network firewalls.


 


Cluster failed to start. The latest copy of cluster configuration data was not available within the set of nodes attempting to start the cluster. Changes to the cluster occurred while the set of nodes were not in membership and as a result were not able to receive configuration data updates. .

Votes required to start cluster: 2
Votes available: 1
Nodes with votes: ABCD-xyz04 ABCD-xyz03 ABCD-xyz05

Guidance:
Attempt to start the cluster service on all nodes in the cluster so that nodes with the latest copy of the cluster configuration data can first form the cluster. The cluster will be able to start and the nodes will automatically obtain the updated cluster configuration data. If there are no nodes available with the latest copy of the cluster configuration data, run the 'Start-ClusterNode -FQ' Windows PowerShell cmdlet. Using the ForceQuorum (FQ) parameter will start the cluster service and mark this node's copy of the cluster configuration data to be authoritative. Forcing quorum on a node with an outdated copy of the cluster database may result in cluster configuration changes that occurred while the node was not participating in the cluster to be lost.

Description

The cluster service has determined that this node does not have the latest copy of cluster configuration data.
Therefore, the cluster service has prevented itself from starting on this node. Try starting the cluster service on all nodes in the cluster. If the cluster service can be started on other nodes with the latest copy of the cluster configuration data, this node will be able to subsequently join the started cluster successfully. If there are no nodes available with the latest copy of the cluster configuration data, please consult the documentation for 'Force Cluster Start' in the failover cluster management snapin, or the 'forcequorum' startup option. Note that this action of forcing quorum should be considered a last resort, since some cluster configuration changes may well be lost.

Cause :


This event is logged when cluster service has determined that this node does not have the latest copy of cluster configuration data.

Resolution :

Review location of the latest cluster configuration and start cluster accordingly

One of the nodes does not contain the latest copy of the cluster configuration, which means the Cluster service will not start on that node. Try starting the Cluster service on all other nodes in the cluster. If the Cluster service can be started on a node with the latest copy of the cluster configuration data, then the node that previously could not be started will probably be able to obtain the latest copy and then join the cluster successfully.

If there are no nodes available with the latest copy of the cluster configuration, use the Force Cluster Start command. This action should be considered a last resort, because some cluster configuration changes could be lost.

To perform the following procedure, you must be a member of the local Administrators group on each clustered server, and the account you use must be a domain account, or you must have been delegated the equivalent authority.



Research Notes:-

This issue happened in the environment because of changes in AD. After reverting the change, all got fix.
