Event ID 1541 — Backup and Restore Functionality in a Cluster

Updated: November 25, 2009

Applies To: Windows Server 2008 R2

red

Successful backup and restore requires certain preconditions. The failover cluster must be running and must have quorum. Software used for backup and restore must be compatible with the Volume Shadow Copy Service (VSS) and with the VSS Writer used by failover clusters. For complete success in a restore, all nodes must be running throughout the time when the restore is performed. Also, the account used by the person performing the backup or restore must be an administrative account.

Event Details

Product: Windows Operating System
ID: 1541
Source: Microsoft-Windows-FailoverClustering
Version: 6.1
Symbolic Name: SERVICE_BACKUP_NOQUORUM
Message: The backup operation for the cluster configuration data has been aborted because quorum for the cluster has not yet been achieved. Please retry this backup operation after the cluster achieves quorum.

Resolve

Retry backup or restore

An operation that was attempted as part of a backup or restore did not succeed. Check for the following preconditions to make sure they have been met, and then retry the backup or restore operation:

  • The cluster must achieve quorum. In other words, enough nodes must be running and communicating (perhaps with a witness disk or witness file share, depending on the quorum configuration) that the cluster has achieved a majority, that is, quorum. For more information about quorum, with the Failover Cluster Management snap-in open, click Help, click Help Topics, click the Search tab, and search for quorum. Open the topic called Understanding Quorum Configurations in a Failover Cluster.
  • The account used by the person performing the backup must be in the local Administrators group on each clustered server, and must be a domain account, or must have been delegated the equivalent authority.

Verify

Confirm that the nodes are running and that the backup or restore process succeeded.

To perform this 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.

Viewing the status of the nodes in a failover cluster

To view the status of the nodes in a failover cluster:

  1. To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Management. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. In the Failover Cluster Management snap-in, if the cluster you want to manage is not displayed, in the console tree, right-click Failover Cluster Management, click Manage a Cluster, and then select or specify the cluster that you want.
  3. If the console tree is collapsed, expand the tree under the cluster you want to manage, and then click Nodes.
  4. View the status for each node. If a node is Up, the Cluster service is started on that node.

Another way to view node status is to run a command on a node in the cluster.

Using a command to view the status of the nodes in a failover cluster

To use a command to view the status of the nodes in a failover cluster:

  1. On the node that you are checking, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. Type:

    CLUSTER NODE /STATUS

    If the node status is Up, the Cluster service is started on that node.
