How to Disable a Cluster Disk Driver in windows 2012

Hi,

I am trying to find out is there any change in accessing cluster/shared drive in Windows 2012 without starting the cluster service?

Earlier in Windows 2003 we use to go to Non Plug and Play devices and disable the Cluster disk driver. In Windows 2008 Cluster Disk driver is a true plug and play. Similarly is there any change in Windows 2012 or its same as Windows 2008 ?

Kindly let me know if any one tried this option, this is really helpfull in troubleshooting disk/LUN related issues in cluster environment.

CSV online (no access)

We have a HP P2000 G3 SAN and have 2 Servers running WS2012.  I have configured Failover clustering and Presented one of the LUNS usning iSCSI to one of the servers to start.

I have then configured that disk as a CSV, it goes online but then immediately changes to online (no access)

the ClusterStorage folder in c: is there but the subfolders are not created and I can not add the VHDX files and appropraite folders to this volume as there is insufficient space on the c: ie the cluster is not available.

Would appreciate any thoughts or advice on this.

Network settings failover cluster

Hi,

During configuring the failover cluster, everything went fine and all the test were succesful. However, during configuring the network settings, I had to choose an IP-address. But it only showed one subnet (the one with my internet switch) and not the internal subnet (the 172.16.0.x subnet). So I thought, strange but OK I had no other choise. So I configured the cluster IP with a 10.0.2.x. But now (I think of course) it can't find my DNS server. It keeps complaining about DNS time out etc. When I configure a DNS on that subnet, it can find the that DNS server.

But I think that configuration is not the right configuration. Is this still right or do I have to change something so that I can configure an IP-address with the 172.16.0.x subnet?

I crawled the whole forum but nothing similar like this came up.

Thank you so much for the help!

I installed KB2520235 on the first node of a two node cluster successfully.  The second node told me KB was Not Applicable. Now Validation report complains about the update difference. Why does the second node think KB Not Applicable?  Hardware/OS same.  What's the impact of the difference on the cluster?  How do I correct the anomaly?

Failure to see iSCSI nodes in Cluster Validation test

Hi,

I've been trying to build a WS2012 cluster using a Dell MD3200i (with the 4/12/12 release supported firmware) and am getting the following warnings when running the Storage tests:

Physical disk 468a27fb is visible from only one node and will not be tested. Validation requires that the disk be visible from at least two nodes. The disk is reported as visible at node: vm-node-01.dom.com
Physical disk e4841603 is visible from only one node and will not be tested. Validation requires that the disk be visible from at least two nodes. The disk is reported as visible at node: vm-node-02.dom.com
Physical disk 468a27fb is visible from only one node and will not be tested. Validation requires that the disk be visible from at least two nodes. The disk is reported as visible at node: vm-node-02.dom.com
Physical disk e4841603 is visible from only one node and will not be tested. Validation requires that the disk be visible from at least two nodes. The disk is reported as visible at node: vm-node-01.dom.com
No disks were found on which to perform cluster validation tests. To correct this, review the following possible causes:
* The disks are already clustered and currently Online in the cluster. When testing a working cluster, ensure that the disks that you want to test are Offline in the cluster.
* The disks are unsuitable for clustering. Boot volumes, system volumes, disks used for paging or dump files, etc., are examples of disks unsuitable for clustering.
* Review the "List Disks" test. Ensure that the disks you want to test are unmasked, that is, your masking or zoning does not prevent access to the disks. If the disks seem to be unmasked or zoned correctly but could not be tested, try restarting the servers before running the validation tests again.
* The cluster does not use shared storage. A cluster must use a hardware solution based either on shared storage or on replication between nodes. If your solution is based on replication between nodes, you do not need to rerun Storage tests. Instead, work with the provider of your replication solution to ensure that replicated copies of the cluster configuration database can be maintained across the nodes.
* The disks are Online in the cluster and are in maintenance mode.
No disks were found on which to perform cluster validation tests.

Stop: 20/12/2012 21:32:31.

Checking through the List Disks task, I can see that both nodes can see the iSCSI and it's mounted against the same LUN (output is identical for both nodes):

22468a27fb690B11C0000DE74D000005C950D15FE829T0062 DELL MD32xxi Multi-Path Disk DeviceiSCSIStor Port2:0:0:10Microsoft Multi-Path Bus DriverTrueDisk partition style is MBR. Disk type is BASIC. Disk uses Microsoft Multipath I/O (MPIO).

Can anyone shed any light on why it would appear to be seeing the disks in one test but not in the other?

We are setup a  failover cluster with 2 node each on separate site for sql server. Node and FileShare witness configured on primary Site. If the primary site fails then cluster will stop. Is there any way we can configure alternate Node and FileShare witness directory on the Second primary site like exchange 2010 Dag. Other wise during the site failure we need to forcequorm on secondary site.

Convert File Server Virtual Machine to Standalone DFS

I want to convert a File Server Virtual Machine to a Standalone DFS, using the same name so that there is no interruption.  I have already created a new volume on my Cluster and robocopy-ed all the files and folders to it.  I have also given the cluster account in ADUC Full Control permissions to the file server account. 

I keep getting this set of errors around the time the clustered service wizard is "configuring network name resource":

An error occurred while creating the DFS Namespace Server.
An error occurred while creating a client access point for 'server'.
Failed to save client access point changes.
Failed to update the network name.
An error occurred renaming resource 'server (2)' to 'server'.
Cannot create a file when that file already exists

What does this mean?  I know this is doable - I have done it before - but I keep getting these errors.  Any advice?

How to set private properties of a cluster resource using WMI?

Hi,

I wanted to know if there is an easier way to set or modify private properties of cluster resource using WMI from managed code (C#). One way I can think of is using ExecuteResourceControl Method of the MSCluster_Resource class to invoke CLUSCTL_RESOURCE_SET_PRIVATE_PROPERTIES control code. Is there a simpler way?

Thanks in advance for any help,

validate failover of two node Windowsi server 2008 R2 failover cluster

Hi Forum,

 I have setup a new two node windows failover cluster. It has shared quorum and a disk that contains Hyper v VM (LUN). To validate the failover wedisabled all the NIC cards in node 1(which is the current owner) including heartbeat and data .The automatic failover fails and the failover service in node 2 enters stopped mode.

But The validation report passes without any error. when I try to move the VM between two nodes its successfully moves and also when I hard shutdown the nodes then also failover is successful.

I have worked in VMware and I used to validate failover by disabling the nic's. So I have tried the same method here.

I don't have big understanding how windows  failover occurs so any help in this regard will be greatly appreciated. 

regards

Cluster Shared Volume disks report Online (No Access)

Hi, bit of a strange one here...

We're currently testing out a Hyper-V Failover Cluster on Windows Server 2012 RC. We are using shared storage (HP P4300 cluster) which is working just fine and giving no errors either as standalone disks or as witness disks on the cluster. We have the HP P4000 DSM installed and working, again with no errors.

The problem is that when we add an available volume (reported as online available storage) to the cluster shared volumes, they come up, briefly report as Online, and then revert to a state of Online (No Access). They do not appear in C:\ClusterStorage on either of the cluster member nodes. There are no errors (or warnings, or even informational events) in the cluster event log or windows event logs, and I can find no way of resolving the issue.

To further confuse matters, if I put the disk into Maintenance Mode, it changes to Online (In Maintenance), successfully mounts itself on its owner node, and allows me to add files etc.

I can find no reference to the state Online (No Access) aqnywher in teh Googleverse, so if anyone knows what's going on, I;d be very grateful of pointers!

Thanks in advance,

Pete

Missing a VM in Failover Cluster Manager

January 4, 2012, 1:30 pm

We did eventually cut the power when shutting down the second of the two hosts in the cluster, because it got stuck at some stage during shutdown. The reason we shut down was that there were problems piling up while we moved VMs between the two nodes.

After boot, we no longer see one of the virtual machines in the Failover Cluster Manager. In Hyper-V Manager we see it, and it runs just fine.

How can we add the missing VM back in Failover Cluster Manager? Is there a simple way?

All the servers are Win 2008 R2.

Maybe a simple question - I don't know - but we just don't have enough knowledge right now, nor has searching the net resulted in anything useful. Appreciate a bit of help holding our heads above water while we learn to swim.

Windows FAilover Clustering Name Resource Fails

December 24, 2012, 5:00 am

Hi,

We have configured a Failover cluster for the application and configured the same. Everything was working fine but suddenly it failed. Now when we are trying to create a Failover Cluster Again we are not able to bring the Name Resource for the Application online.

The Cluster Account(Cluster1) is configured with proper Security Settings to provide full permission to the Cluster Account(Cluster1$). When we have configured the application it had created a application name account in AD (Cluster2). We have configured that account as well to provide full access to (Cluster1$).

Now whenever we are trying to bring the Name Resource for application online we are getting the below errors:

===============================================================================================

Cluster network name resource 'Cluster2' cannot be brought online. The computer object associated with the resource could not be updated in domain Domain.com for the following reason:
Failure in validataing Computer object properties for a virtual network name account.

The text for the associated error code is: You were not connected because a duplicate name exists on the network. If joining a domain, go to System in Control Panel to change the computer name and try again. If joining a workgroup, choose another workgroup name.

 
The cluster identity 'cluster1$' may lack permissions required to update the object. Please work with your domain administrator to ensure that the cluster identity can update computer objects in the domain.

================================================================================================

Is it because the application account is already existing in the AD. What will be the impact if we delete the account from AD and try to bring it online.

Continuous Availability in Windows Server 2012 Storage Spaces write performance drop

Hi there!

we built a test Environment for Storage Spaces and Hyper-V with SMB 3.0. We have 8 SAS discs in a JBOD box. We connected two supermicro Servers. We get the expected Performance out of the discs until we activate continuous availability for Fileserver or scale out Fileserver. Before we activate it, we get a write peformance (just simple copying of large files) about 200-400 MB/sec. Once the continous availability is activated it drops to 38MB/sec.

Is this a "normal behavior"? Did we configure something wrong? Again, this is reporduceable. You can switch this option on or off which leads to an speed increase and decrease. I think the write cache is switched off in continuous availability, but is the impact really that high?

Thanks for any help!

NLB from host inside the cluster

December 24, 2012, 8:54 am

Hi all,

We have setup of NLB cluster (multicast - Windows 2008 R2) with different ports (all ports are TCP, with Multiple host filtering mode and None affinity). Here is an example:

HostA, HostB, HostC has configured NLB with service1 (as described above on some particular port).

On HostA we stop service1 (not on NLB but actual stop the service) and then when we try from HostA to contact NLB address for that service we get timeouts (even though service1 is still running on other hosts). Like it is communicating only with himself and we are using cluster IP address. The same is happening no matter if service1 has Status Enabled or Disabled on NLB HostA.

We need this kind of setup for fail-over reason. Our application which runs on HostA firstly checks if service1 is available locally but if it is not it will try to ask NLB for that service1. But as I described we get timeouts.

Everything is working normally if we test from outside these hosts, but when trying directly from hosts inside the cluster this problem appears.

Is there any reason why is this happening and why other hosts in NLB are not contacted. 

Thanks in advance,

Bogdan

Online VMs from node 1 were live migrated to node 2.  Then node 1 was patched and rebooted.

Presently we have 1 server  with Windows 2012 DataCenter Edition(Used for Internal Application),Would appreciate if somebody could answer the possibilities of the below 

 "The Environment include  a  EMC FC SAN ."

- Is it possible to cluster the above physical machine with another VM (Windows 2012 Standard Edition) running on another physical host

- if not  what is the possibility of having the high availability between the Physical and VM using Windows 2012

NOTE:-  Both servers have dissimilar hardware and operating Systems

Powershell Get-Cluster "A remote API error occurred"

I'm having an issue on my network where Powershell is returning the following error when invoking the command Get-Cluster:

get-cluster -domain mgmt.local
Get-Cluster : Could not retrieve the list of clusters on the network.
    A remote API error occurred
At line:1 char:12+ get-cluster <<<<  -domain mgmt.local+ CategoryInfo          : NotSpecified: (:) [Get-Cluster], ClusterCmdletException+ FullyQualifiedErrorId : Get-Cluster,Microsoft.FailoverClusters.PowerShell.GetClusterCommand

The domain name used does not matter - even a ficticious domain name results in the same error, so I can confirm that the domain controllers are not responsible for the error.

This problem only occurs when using the -domain switch.  Using -name works fine.  I unfortunately need to rely on the -domain switch so that I can get a list of all my clusters.

All the machines I've used are Windows 2008 R2 SP1 with the latest updates. I've even tried the command on the domain controller itself, same response.

I've only started experiencing this problem since yesterday.  Up till then, this command has always worked for me.  I have done no changes that could attribute to this error.

Virtual Machines, Failover Cluster and SCVMM

Hi,

I can't get this clear. I configured successfully a Failover Cluster and now I want to create Virtual Machines. However, when I create a VM in the Failover Cluster, it is not replicated. If I want to replicate the VM, I can't replicate it to the same cluster. So I have to create a VM on Hyper-V and then replicate it to the cluster. But then the VM is not in the cluster (only the replication). Then whats the reason why I can configure a VM in the Failover Cluster? Whats the added value? Or should I configure VMs in System Center Virtual Machine Manager? Brings that a added value in the context of creating VMs?

Hope someone can help me on this because I can't figure this out how I should successfully create a High Availability VM.

Thanks!!
