Microsoft Windows Server 2008 Failover Cluster. Of a Microsoft Windows 2008 Failover Cluster by retrieving. Event ID: 1000, 1006, 1073, 1146. Event ID 1146 and 1069 - strange failover scenario. Discussion in 'SQL Server Clustering' started by franco, Aug 4, 2005. Franco New Member. Hi all, I would like to share with you a strange situation that we notice on a 2 node cluster, windows server 2003 - no service pack. The cluster is configured as follow: Node A hosts SQL Server 2K sp3a and file system Node B hosts Oracle 9i and Lotus. Troubleshooting cluster issue with Event ID 1135. Content provided by Microsoft. What does this guide do? Helps you diagnose and resolve Event ID 1135 which may be logged during the startup of the Cluster service in Failover Clustering environment. Who is it for? Administrators who help solve Event ID 1135 for the Cluster service. How does it work? We’ll take you through a series of.

If you do not currently have Event Viewer open, see 'Opening Event Viewer and viewing events related to failover clustering.' To perform these procedures, 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. Configuring a resource to run in its own Resource Monitor To configure a resource to run in its own Resource Monitor: • To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Management.

These represent some of the more common issues in supported Windows 2008 R2 Failover Clusters, as well as the steps you may need to take to resolve them. Scenario 1: We were doing our monthly scrubbing of Active Directory objects and inadvertently deleted the Cluster Name Object. We tried to create a new one, but it fails to come online. The Cluster Name Object (CNO) is very important, because it’s the common identity of the Cluster. It’s created automatically by the Create Cluster wizard and has the same name as the Cluster. Through this account, it creates other Cluster Virtual Computer Objects (VCOs) as you configure new services and applications on the Cluster.

But this meant that if one resource crashes then the entire RHS process could fail and all resources hosted by this RHS will fail. We’ve improve our default behavior in 2008 R2 by separating our critical resources from our dlls in RHS. Now the Cluster Group (including the quorum resource) and Storage Group (including Available Storage and Clustering Shared Volumes) now all run in a single, isolated RHS process. The other resource dlls will run in one or more additional RHS processes. There are two common reasons for seeing instability in a resource dll: 1. The resource dll itself may crash. In most cases this is caused by an access violation in the resource dll.

The resource dll might take too long to perform requested action, in some cases it might even deadlock. There is not effective way to detect if it is just taking long time or there is a deadlock. One way to solve this issue is to limit amount of time we are waiting for the resource to complete request, and if it does not complete in that time we would assume that the component handling this call is not in a healthy state. Some activities, such as online and offline, can take some time, so you may see the ‘pending’ state in the UI. If online is taking a long time, the resource might spawn a worker thread, and tell RHS that online call is pending, which can notify RHS that it requires more time. Once the resource comes online it will notify RHS. Offline is handled in the similar way.

In this blog I will discuss how Failover Clustering communicates with cluster resources, along with how clustering detects and recovers when something goes wrong. For the sake of simplicity I will use a Virtual Machine as an example throughout this blog, but the logic is generic and applies to all workloads. When a Virtual Machine is clustered, there is a cluster “Virtual Machine” resource created which controls that VM.

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.

On the Filter tab, in the Event sources box, select FailoverClustering. New holland tractor serial number location. Select other options as appropriate, and then click OK.• To sort the displayed events by date and time, in the center pane, click the Date and Time column heading.

These packets are supposed to be received by the other nodes and then a response is sent back. Each node in the Cluster has its own heartbeats that it is going to monitor to ensure the network is up and the other nodes are up. The example below should help clarify this: If any one of these packets are not returned, then the specific heartbeat is considered failed. For example, W2K8-R2-NODE2 sends a request and receives a response from W2K8-R2-NODE1 to a heartbeat packet so it determines the network and the node is up.

If you delete the CNO or take permissions away, it can’t create other objects as required by the Cluster until it’s restored or the correct permissions are reinstated. As with all other objects in Active Directory, there’s an associated objectGUID. This is how Failover Cluster knows you’re dealing with the correct object.

On W2K8-R2-NODE2, the Cluster Service is terminated and then restarted so it can try to rejoin the Cluster. For more information on how we handle specific routes going down with 3 or more nodes, please reference blog that was written by Jeff Hughes. Now that we know how the heartbeat process works, what are some of the known causes for the process to fail.

In the properties for all network adapters that carry cluster communication, make sure “Client for Microsoft Networks” and “File and Printer Sharing for Microsoft Networks” are enabled to support Server Message Block (SMB). This is required for CSV. The server is running Windows Server 2008 R2, so it automatically provides the version of SMB that’s required by CSV, which is SMB2. There will be only one preferred CSV communication network, but enabling these settings on multiple networks helps the Cluster have resiliency to respond to failures. Redirected Access means all I/O operations are going to be “redirected” over the network to another node that has access to the drive. There are basically three reasons why a disk is in Redirected Access mode: • You’ve manually placed it in Redirect Mode • There’s a backup in progress • There are hardware problems, and the node can’t directly access the drive In our scenario, we’ve ruled out Option 1 and Option 2. This leaves us with Option 3.

On the Filter tab, in the Event sources box, select FailoverClustering. Select other options as appropriate, and then click OK.• To sort the displayed events by date and time, in the center pane, click the Date and Time column heading. 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: • 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.• 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.• If the console tree is collapsed, expand the tree under the cluster you want to manage, and then click Nodes.• View the status for each node.

If W2K8-R2-NODE1 sends a request to W2K8-R2-NODE2 and W2K8-R2-NODE1 does not get the response, it is considered a lost heartbeat and W2K8-R2-NODE1 keeps track of it. This missed response can have W2K8-R2-NODE1 show the network as down until another heartbeat request is received. By default, Cluster nodes have a limit of 5 failures in 5 seconds before the connection is marked down.

Consider configuring the resource to run in its own Resource Monitor. Note that while a problem with a resource DLL will not stop the Cluster service from running, it can prevent other resource DLLs from running unless the resource runs in its own Resource Monitor. If you do not currently have Event Viewer open, see 'Opening Event Viewer and viewing events related to failover clustering.' To perform these procedures, 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.

A common problem can be due to third-party resource dlls which may not have had the detailed level of testing as the in-box dlls. In previous releases we offered the ability to isolate components into separate processes, and in 2008 R2 we have built in additional isolation logic, so that if a resource dll crashes, little else is affected, offering even higher availability to your mission-critical applications. The resource dll is a component is provided by the application being clustered and is a proxy between the application and the cluster. If the cluster wants to stop or start the application it will notify the resource dll, and resource dll will communicate this information to the application. The cluster does not load the resource dlls into the cluster service process, instead it loads them into the Resource Host Monitor (RHS.exe) process, which is recyclable. Previously all resources used to run in a single RHS process by default.

• 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. • If the console tree is collapsed, expand the tree under the cluster you want to manage, and then click Nodes. • View the status for each node.

The RHS.exe process in a Windows Server 2008 Failover Cluster crashes unexpectedly when running Storage Foundation for Windows (SFW) 5.1 SP1. The crash information points to vxres.dll as the possible cause. RHS is the Failover Cluster's monitoring process which continually checks the health/status of all resources that are configured in the cluster to ensure the resources remain in their proper state (i.e. Online); this includes the 'Volume Manager Diskgroup' resource which is represented by vxres.dll. Errors: Below is a list of errors that are reported to the Event Logs. Cause: An issue was found with the Volume Manager Diskgroup resource (vxres.dll) which resulted in the RHS crash. Solution: This issue has been identified and a private fix is available from Veritas Enterprise Technical Support.

Running a Performance Monitor would be a good place to start. Updating drivers/firmware of the cards or the back end may be something to consider as well. You’re also going to be doing some user mode detections.
