Windows Failover Cluster (Errors retrieving file shares)

I'm having an issue with Windows Failover Cluster with a Windows Server 2012 R2  machine. I have two cluster nodes (nodeA and nodeB). My issue is that when nodeA is the owner node, and I open failover cluster manager  <clusterName> >> roles >> <fileserver role> >> shares tab it will hang and say that it is loading, but this will occur infinitely. Although when I go to nodeB (not the owner node) and I go to shares it will show me all of the shares that I have. Next when I go to <clusterName> >> Nodes  >> click on Roles tab the information says "There were errors retrieving file shares."

Now when I switch the nobeB to the owner node, I cannot view the shares on that machine but can now view them on nodeA. 

We alse have a test network where I have recreated the machines, environment and the failover cluster to as close as the production network as I can except everything works great in the test network

Adding nodes to Windows Server 2008 R2 Hyper-V Cluster..

Currently we have a 3 node Windows Server 2008 R2 Hyper-V Cluster in production. There are about 3 terrabytes worth of VMs running across these nodes.

It is over-committed, so i've setup two new nodes to add to the cluster.

I've done this before in a SQL cluster but never a Hyper-V cluster.

If I don't run validation when adding the nodes, will there be downtime?

The quorum is setup for disk majority, everything is identical on all nodes that needs to be. Shared storage is recognized and ready on the new nodes. I've gone through every checklist that Microsoft has. I'm just curious if the virtual machines will go offline on the current nodes when i add the two new nodes.

Everything is identical down to the wsus updates installed. From networking to storage everything is perfect.

I don't want to run validation as I know that'll take everything offline.

Multiple Event ID's 4738 and 4724 on new Windows 2012 Hyper V cluster

We just setup a two node Windows 2012 Hyper V cluster.  Everything is working correctly, but in the Security log on both nodes, we're getting Event ID's 4738 and 4724 every 3 minutes for the built in CLIUSR (Failover Cluster Local Identity) that gets created with the cluster (there's a local CLIUSR account on each node).  Because we have an application that parses the security logs and emails us about user account changes, we're getting spammed because of this.  Does anyone know if this is normal behavior for that CLIUSR account?  Any way to suppress this?  On the account properties, "User cannot change password" and "Password never expires" are both checked.  I appreciate any insights people might have.  Thanks

Any one please respond.



I've been working on creating a windows server 2008 R2 cluster for about a month now and I keep getting an error whenever I try to add a 2nd node. I keep getting The cluster node is not reachable. However, when I validate the configuration, everything goes through success. I created and destroyed the cluster a couple of times, but no luck. I even re-installed Windows Server 2008 R2 on both servers, re-configured the iSCSI, and the same warning keeps coming up. 

I installed a new a new SQL Server 2008R2 Named Instance on an exisiting SQL Server cluster node (Node 1 &Node2). When I try to manually fail over 

the Services and applications  to another node (Node1 to node2) using Failover Cluster Manager, I get the errors

The cluster has these Events:

Event ID1069: Cluster resource 'IP Address xx.xx.xx.xx' in clustered service or application 'ClusterDtc' failed.

Event ID 1205:The Cluster service failed to bring clustered service or application 'ClusterDtc' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application..

Why the cloud server doesn’t move to node2? you can see screen shorts below.

in system configuration-

3. in system configuration---->warning--->Validate All Drivers Signed

after creating cluster I got below errors.

Any info you might know would be really helpful.

Hi All,

We are having a cluster with two nodes and I found one node down also cluster service is in stopped. While trying to start the service we are getting errors. Server has been rebooted. I found some errors in cluster log file I have attached below:

This is Windows 2003 cluster. If anyone can find some solution will be very helpful.

DHCP Failover strategy

Hi. 

I would like to configure a DCHP server failover on Windows 7.

On a part I have a windows 2008 R2 server which currently leases adresses. I recently had a crash of this server.

In order to insure avaibility of dhcp on the next crash, I whish install a DHCP server freeware and configure a script powershell to start dhcp on failover of the first one.

An other tip is to split the pool of leasing. Is it possible to do it with a windows 7 software?

Thanks a lot for your help.

Dear Support,

I have install NLB feature on two windows 2008 R2 servers both have configured with IIS. However I have tested both are working fine and both are accepting the request successfully.

Since we have performed load test the load balance between the server is not equal

Host 1

CPU Utilization =53%

Host 2

CPU Utilization = 10%

Please suggest.

Nics for a Hyper-V cluster

Hello!

http://alexappleton.net/post/44748523400/step-by-step-configuration-of-2-node-hyper-v-cluster-in

Each server has a total of 8 NIC’s and they will be used for the following:

1 – Dedicated for management of the nodes, and heartbeat
1 – Dedicated for Hyper-V live migration
2 – To connect to the shared storage appliance directly
4 - For virtual machine network connections

Tell me please whether I'm right or not:

1) 1 – Dedicated for management of the nodes, and heartbeat - it's not good: it's better to have a separate Nic decicated  for heartbeat and a NIc  dedicated for management.

2) I can use the same Nic(s) for the nodes management and for virtual machine network connections.

Thank you in advance,

Michael

Cluster Shared Volume (CSV) not failing over on Hyper-V 2-node Cluster

March 18, 2014, 8:49 am

Hi,

We have a 2-node Hyper-V cluster in testing and I'm having a problem with the disks on it. Both nodes have 1 storage HBA each which connect to a SAN over 2 switches (the nodes stay connected as long as 1 switch is running). On the SAN I have a volume configured as a CVS that contains all VM info and VHDs. The quorum volume is also on the SAN.

In Failover Cluster Manager under Storage > Disks I have the Hyper-V volume and it's assigned to to Cluster Shared Volumes. It is set to owner node 1 in this instance.

Now whenever I simulate a HBA failure on Node 1 (I just remove the cables) the Hyper-V CVS will go offline and stay offline, taking the VM roles with it. Is it not supposed to failover to Node 2 and redirect access via Node 2 to Node 1? Should it be in redirected access? I also have the owner node of the Disk Witness set to Node 2 and when I "fail" the HBA on Node 2 the quorom also goes offline. My quorum is set to Node and Disk Majority, should it be Node and File Share Majority for a SAN volume?

I appreciate all the help in advance.

EDIT: just some more info, when the cluster fails to bring the CSV back online after the HBA fails and I try to move it to Node 2, it will give me an error: Move didn't complete can't find the file specified.

Cannot connect to Cluster

Three questions, I had two (Primary and Replica) Server 2012 R2 physical hyper-v hosts running VM replication. This was working perfectly...even did a planned and non-planned failover...awesome. I then proceeded to install Failover Clustering, added the two hosts to a cluster, validated them and created the cluster (DAVGeoClusterTest cluster name get's truncated to DAVGeoclusterte), so far so good. IT was end of the day so i stopped right there, basically stopped at the end of the Create Cluster Wizard. A day later i cannot see the cluster in Failover Clustering Manager, I try to connect to it and I get "The RPC Server is Unavailable - Exception from HRESULT: 0x800706BA" any ideas? Also i can only Remote Desktop into one of the two WMs at a time, the other loses connectivity, is this to avoid the split brain problems? Is there a way to totally undo/delete and go back to my simple VM replication I had going?

Hi,

I have created a two node cluster in my environment. After creating the cluster service, it reports me the following error and warning,

Warning

Event ID – 1579

Cluster network name resource 'Cluster Name' failed to update the DNS record for name 'MyCluster' over adapter 'PRO'. The error code was 'DNS bad key. (9017)'. Ensure that a DNS server is accessible from this cluster node and contact your DNS server administrator to verify the cluster identity can update the DNS record 'MyCluster'.

Error

Event ID – 1196

Cluster network name resource 'Cluster Name' failed registration of one or more associated DNS name(s) for the following reason:

DNS bad key.

Both the cluster node servers are running Windows 2008 R2 Enterprise, Service pack 1

My environment has a third party DNS setup. After some searching I found out that this problem can occur when I use a third-party server application for DNS resolution. But I could not apply the fix. It reports me “This hot fix is not applicable to your system”. May be I have already got the fix.

Does anybody know how to fix this issue?

Thanks in advance.

Windows 2012 Multi-site cluster, quorum configuration question

We are working on building windows 2012 multi-site cluster for SQL 2012 AgAO solution. The Site-A has two nodes and a file share where as site-B has two nodes.  Looking at the quorum configuration recommendation, which says the nodes on site-B should be configured for 0 vote, only the nodes on Site-A should be configured to vote. If so, then the question is why do we need file share vote? can we confgure two node on primary side (that has vote) and two node on secondary site (which does not vote)? What would go wrong if we do not add file share vote on primary site?

Please let me know any additional information required?

Hi,

We have implemented a two node Windows fail-over cluster on which SQL server instance has been installed. As part of Fail-over testing, we have disabled network adapter in first node (preferred owner) and the SQL instance moved to the second node without any issue. But when we tried to enable network adapter and move back the SQL instance to first node it fails. The status is like Online Pending for sometime and will become Failed. We are getting Cluster event logs error like 1069 and 1205. We tried to check with all possible solutions in the internet referring to this event ID (1069 and 1205) with no luck.

We also tried the solution for this issue "SQL Server cluster resource goes to a "failed" state when you try to bring the resource online in SQL Server" http://support.microsoft.com/kb/883732 provided in Microsoft support page too by checking registry resource parameters and could not find any missing parameter in the registry side also.

So can anyone help us regarding this issue?

Unable to connect to cluster using Failover Cluster Manager

March 20, 2014, 8:12 am

In the last day or so I've discovered that I'm no longer able to connect to my cluster using Failover Cluster Manager.  When I try to connect it gives me the error "An error occurred connecting to the cluster <cluster name>.  An error occurred trying to display the cluster information.  One or more errors occurred."

If I log onto the node that's hosting the "Cluster Group" cluster resource, and open Failover Cluster Manager and connect to <Cluster on this server...> it gives me a similar message.

As far as I can see, the Cluster Powershell commands still work, so I've moved the "Cluster Group" group to another node, but I am still unable to connect to the cluster using Failover Cluster Manager.

The Cluster Service is running, and I'm reluctant to restart it becuase I know my Virtual Machines are going to start failing or failing over when I do this.

I have verified that I am logged in as a super-duper user, even tried logging as the Domain Administrator with no luck.  I have also tried the WMI Mofcomp suggestion as described in http://www.yusufozturk.info/windows-server/failover-cluster-manager-an-error-occurred-to-display-cluster-information.html with no luck.

Any suggestions?
