Articles, code, and a community of database experts. Prerequisites WMI access to the target server. Credentials Windows Administrator on the target server. Backup and Restore Functionality Problems Returns the number of events that occur when: The backup operation for the cluster configuration data has been aborted because quorum for the cluster has not yet been achieved; The restore request for the cluster configuration data has failed during the "pre-restore" or "post-restore" stage.
Check for the following pre-conditions 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. 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.
During a restore, the restore software must obtain exclusive access to the cluster configuration database on a given node. If other software has access open handles to the database , the restore cannot be performed. Cluster Network Connectivity Problems Returns the number of events that occur when: The Cluster network interface for some cluster node on a special network failed; The Cluster network is partitioned and some attached failover cluster nodes cannot communicate with each other over the network; The Cluster network is down; The Cluster IP address resource failed to come online; Attempting to use IPv4 for a special network adapter failed.
Cluster Service Startup Problems Returns the number of events that occur when: The Cluster service suffered an unexpected fatal error; The Cluster service was halted due to incomplete connectivity with other cluster nodes; The Cluster service was halted to prevent an inconsistency within the failover cluster; The Cluster resource host subsystem RHS stopped unexpectedly; The Cluster resource either crashed or deadlocked; The Cluster service encountered an unexpected problem and will be shut down; The Cluster service has prevented itself from starting on this node.
This node does not have the latest copy of cluster configuration data. The membership engine detected that the arbitration process for the quorum device has stalled. Review events related to communication with the volume. Check storage and network configuration. Check Cluster Shared Volumes folder creation and permissions. Check communication between domain controllers and nodes. Cluster Storage Functionality Problems Returns the number of events that occur when: The Cluster Physical Disk resource cannot be brought online because the associated disk could not be found; While the disk resource was being brought online, access to one or more volumes failed with an error; The file system for one or more partitions on the disk for the resource may be corrupt; The Cluster disk resource indicates corruption for specific volume; The Cluster disk resource contains an invalid mount point.
Confirm that the affected disk is available. Confirm that the mounted disk is configured according to the following guidelines: Clustered disks can only be mounted onto clustered disks not local disks ; The mounted disk and the disk it is mounted onto must be part of the same clustered service or application. Cluster Witness Problems Returns the number of events that occur when: The Cluster service failed to update the cluster configuration data on the witness resource due to resource inaccessibility; The Cluster service detected a problem with the witness resource; The File Share Witness resource failed a periodic health check; The File Share Witness resource failed to come online; The File Share Witness resource failed to arbitrate for the specific file share; The node failed to form a cluster because the witness was not accessible.
Configuration Availability Problems Returns the number of events that occur when: The cluster configuration database could not be loaded or unloaded; The cluster service cannot start due to failed attempts to read configuration data. Encrypted Settings for Cluster Resource Could not Applied Returns the number of events when encrypted settings for a cluster resource could not be successfully applied to the container on this node. Event ID: Event ID: , File Share Resource Availability Problems Returns the number of events that occur when: The Cluster File Share cannot be brought online because a file share could not be created; The retrieving of information for a specific share returned an error code; The retrieving of information for a specific share indicated that the share does not exist; The Creation of a file share failed due to an error; The Cluster file share resource has detected shared folder conflicts; The Cluster file server resource failed a health check because some of its shared folders were inaccessible.
Ensure that no two shared folders have the same share name. Check shared folder accessibility and the State of Server service. Generic Application Could not be Brought Online Returns the number of events that occur when a generic application could not be brought online during an attempt to create the process due to; the application not being present on this node, an incorrect path name, or an incorrect binary name.
Confirm that the following are true for the application used by the clustered Generic Application instance: The application is fully installed on all nodes that are possible owners of the Generic Application resource; The configuration for the Generic Application resource specifies the correct application and path; The configuration for the Generic Application resource specifies the appropriate parameters and settings for registry replication. Generic Service Resource Availability Problems Returns the number of events that occur when: The generic service is either not installed or the specified service name is invalid; The specified generic service parameters might be invalid; The generic service failed with an error.
Check service operation and examine the application event log. IP address Resource Availability Problems Returns the number of events that occur when: The Cluster IP address resource cannot be brought online because the subnet mask value is invalid; The Cluster IP address resource cannot be brought online because the address value is invalid; The configuration data for the network adapter corresponding to the cluster network interface could not be determined; The Cluster IP address resource cannot be brought online because a duplicate IP address was detected on the network; The Cluster IP address resource cannot be brought online because WINS registration; The lease of the IP address associated with the cluster IP address resource has expired or is about to expire, and currently cannot be renewed; The IPv6 Tunnel address resource failed to come online because it does not depend on an IP Address IPv4 resource; The Cluster network associated with dependent IP address IPv4 resource does not support ISATAP tunneling.
Network Connectivity and Configuration Problems Returns the number of events that occur when: The Cluster Service was unable to access the network adapter or the cluster node has no network connectivity; The Cluster node has no network connectivity; The Cluster node has lost all network connectivity; The failover cluster virtual adapter failed to initialize the miniport adapter.
Event ID: , , , Note : Best viewed in Internet Explorer 6 and above. Note: As soon as you click move group, Cluster manager start moving resources to NODE15 and you can see the change in status on right pane. Once you highlight the cluster group, on right pane you will see its resources list like cluster name,IP and Quorum disk. I have experience in Mysql server too. Apart from Database, I have good knowledge in PowerShell, Web development Feel free to reach out to me at: support adsql.
The disk is locked by the node owning the "Cluster Group". It is not recommended to keep the Quorum on the OS partition. There should be no data except for the cluster information in that disk.. Yes, typicall thats what a high availablity solution is. Monday, July 13, AM. Thanks Aresh, for the answers.
I have a follow-up question, open of course to anyone that can help. I've been working on my cluster environment, building and re-building it, to get an understading of how it works, what I can and can't do. One idea I'm trying to work out is how to deal with shared drive failure. I'm trying to gather information to see if I could get two nodes both running Windows Server Enterprise in a cluster configuration, each with two drive arrays attached via SCSI one would be designated as primary and one as secondary.
I'm thinking I could possibly use DFS-R to replicate data from the primary array to the secondary array, but I have only found docs on DFS-R replicating to a separate server, as I understand it, outside the cluster. I am almost out of drive space due to there not being any more available drives. There is still storage available on the SAN. The application does not support UNC paths. I have about Gigs free which will get me about 2 more weeks. I need to go about 6 more weeks until the new system is up and we can shut this one off.
Q is the only one left. I've had many "experts" tell me I should be able to just get rid of the Quorum drive but can I? I can't risk removing the quorum drive then the system stops working. True definition of between a rock and a hard place. Is it as simple as just evicting the ghost node from cluster admin?
