Hi all,
I have a cluster installed on windows server 2008 enterprise (not R2). Node1, Node2 and the storage are virtual machines and their host is vSphere ESXI 4.
I am trying to cluster MSDTC following this guide at msdn.microsoft.com/en-us/library/dd897479(v=bts.10).aspx
After I finish 'To configure DTC for high availability (windows server 2008)' I have the resource:
Server Name - when I try to bring this resource online I get the errors: Event ID 1069 and 1194
Thanks in advance,
Sagit
Hi,
Can anyone please help with below mentioned.
Scenario:
01
Initially created the cluster object (CNO) say Cluster1 using windows server logon account say Admin1 having local admin priviledges on both nodes, but when tried adding a service/app to the cluster (as needed to add MSMQ and IIS in cluster) it was throwing permissions error, requesting for domain account priviledges (or create computer objects permission)
02
Hence got the domain admin permission for below:
A) The cluster object i.e. Cluster1 itself
B) On Admin1 account
The cluster resources or say services/apps were then successfully created
Queries:
01
Do we need to maintain domain admin permission for cluster object i.e. Cluster1? If it's removed will there be any impact?
02
Do we need to maintain domain admin permission for account Admin1? If it's removed will there be any impact?
So basically what accounts we need from enduring perspective to manage/administrator the cluster effectively? And precisely what tasks are covered in cluster administration from a production support percpective?
Thanks.

HI!
I have failover cluster on hyper-v core 2008r2.
All vm's use transit disk, based on Iscsi target.
I change nod's to Server 2012 Standard and have a problem.
I can't add storage with installed OS to avaliable storage in cluster, it just say "no avaliable storage", but the disk with no operating system is added.
What can i do?
UPDATE1:
1.Make a clean target
2.add to the clustered disks
3.create VM
4.Give her transit drive
5.set OS
6.Test live megration - works
7.remove the disc from the cluster
8.Back to try to pick up - no drives available!
UPDATE2:
1.Making the disk with the system online
2.Remove the 100MB partition
3.We try to pick up a disk to the cluster - works
UPDATE3:
all disk's with active partition can't be added
Help plz.
In an attempt to check for the status of the cluster,
Namespace: root\mscluster
Query: "SELECT * FROM mscluster_cluster"
The status property for a system that is in a cluster always returns null.
Is this a bug?
Hi there,
I'm seeing these errors sometimes, on a Windows 2012 Hyper-V Failover Cluster.
Cluster Shared Volume 'Volume1' ('Cluster Disk 1') is no longer available on this node because of 'STATUS_IO_TIMEOUT(c00000b5)'. All I/O will temporarily be queued until a path to the volume is reestablished.
There are three nodes, each with 6 NICs. first two NICs are teamed and connected to a VM virtual switch. Second two are teamed (one active) used for cluster comms. Third two are teamed (one active) and connected to a virtual switch - with the management OS and another cluster NIC.
redirected access seems to work fine (tested by removing the CSVs from one node). But it's weird that we keep seeing these on the cluster logs.
Also see STATUS_CONNECTION_DISCONNECTED sometimes too.
Does anyone know what this could be?
Hi Guys
Have a quick questions, in the Win 2003 R2 cluster server, only two of the server is having the more disk utilization out of 3 server. The third is working with good w.r.t performance.
So my cluster is having the 3 servers in total with same OS each having the 8 processors in it. The clusters are are created as virtual machine with vmx-08.Apart from the disk utlization, the processor utilization and memory used are seems to be good for all 3 server.
Could anybody suggest what could be the problem or area to focus to improve the performance of the entire cluster server?

I have a two node cluster running HyperV and the cluster just started spitting out errors that it couldn't bring the clustername online. This is the error message:
Cluster network name resource 'Cluster Name' cannot be brought online. The computer object associated with the resource could not be updated in domain 'mydomain'. The error code was 'Unable to find computer account on DC where it was created'. The cluster identity 'HYPERCLUSTER$' 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.I read through this article: http://blogs.technet.com/b/askcore/archive/2009/04/27/recovering-a-deleted-cluster-name-object-cno-in-a-windows-server-2008-failover-cluster.aspx
I verified that the AD account still exists. This is an isolated environment, so no one else has been mucking with the AD or HyperV servers. I pulled the GUID for the account in AD and it doesn't match the GUID that the cluster wants (from the registry, HKEY_LOCAL_MACHINE\Cluster\Resources\<the resource from ClusterNameResource>\Parameters\ObjectGUID. I tried updating this key on both nodes and then tried to bring the name online, but that still didn't work.
Is there a way to just delete the name that's there and re-create it? Right clicking on the name -> more actions -> repair ad computer account, does nothing. I really don't want to destroy the cluster and re-create it as that would mean downtime for all the VMs.
Hi all,
Environment:
Windows Server 2008 R2 Enterprise Edition across the board.
we have 2 servers that are running lots of applications that run services. those 2 servers are load balanced with a hardware load balancer so both servers have the same exact services running at all times, so when the traffice hit either one it gets processed.
lately we discovered a problem that was caused by the fact that both servers are running the same services, which I don't think the details of it is realevent for this post. bottom line is that our developers asked that we make the service runs on one server at a time and that the services would only start on the second box if the first box is down, which to me sounds like cluster, but we don't need to attached those servers to a SAN, because we don't need to cluster any disks.
so... can we install the cluster and cluster those services as generic cluster resources without having to attach them a SAN?
Thanks
I am testing the ability to create a 3 node Hyper-V cluster using Server 2008 R2.
I am using 3 PowerEdge 840 servers connected to a freenas 8.3 box.
I have created 2 networks 1 for iscsi connectivity and the other for shared host/guest vms and heartbeat (this is only a test scenario but can create a discrete one for heartbeat if needed).
I can successfully create a 2 node cluster with CSV and manually fail over disks / VMs between the 2 nodes. However the moment i add a third node everything starts falling apart. Cluster share volumes take a long time to failover and most of the time go offline. The 3 node config does pass cluster validation including the test for persistent reservations. Have researched at length and for most people it seems the persistent reservations support may have been the issue but in my case i am uncertain if this is the culprit.
Part of cluster log pasted below:

I know the individual nodes are not a problem as i tried all 3 nodes in various 2 node configs and it worked all the time. It is something about the 3 node config that seems to go wrong. In 3 node confg the quorum is set to node majority ands in 2 node it is disk and node majority.
Other things i tried unsuccessfully:
Removed old luns and provisioned brand new luns.
Reduced iscsi initiator name to simply fqdn of the server.
Reduced number of lun presented to just 1.
Any help appreciated. Eventually if this works the aim is to replicate the success to a production environment using a netapp SAN
Currently running a two W2K8 R2 Hosts and setup clustering and the Hyper-V service for HA. They are connected to a iSCSI SAN.
I want to upgrade the network drivers on the host. Is there something special i need to do with the fail-over cluster in order to make this as smooth as possible?
We are new to the cluster world so I apologize if this turns out to be a stupid question. We have a closed/private network that has a database. The DB is MS SQL Server 2008 that is clustered on MS Server 2008 R2 Ent. There are 2 nodes and 1 SAN, the SAN is running MS Server Storage 2008 R2. We have an offsite carbon copy of that setup also, and it will be updated using log shipping. In our domain we are also running MS SCCM 2007 as our means of patching our machines. So finally to our concern, I think I understand how to patch a node in the cluster what I don’t understand is how to patch the SAN. If I just push a patch that requires a reboot when the SAN reboots won’t it kill the cluster? I’ve done some hunting for this info and I can only seem to find info on patching the nodes, not the SAN. Can anyone give me some info about this?
Thanks for looking and any help that you can provide.
Hi all,
Would anyone please tell me the solution to solve the error?
I had tried to backup 1 of Cluster servers. After restored, the cluster service cannot be started, and it's failed to connect to the quorun disk.
I have repaired the quorun disk setting in server manager, the cluster service is started successfully, but there are some warning messages were shown in the eventviewer for every 15 minutes;
"The Cluster service failed to bring clustered service or application 'Cluster Group' 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."
"Cluster resource 'Cluster Disk 2' in clustered service or application 'Cluster Group' failed."
"The cluster service detected a problem with the witness resource. The witness resource will be failed over to another node within the cluster in an attempt to reestablish access to cluster configuration data."
In the cluster.log, the following records were found;
00000ce4.00001f48::2010/12/17-08:40:09.305 ERR [QUORUM] Node 2: Failing quorum resource due to witness failure

Hi,
my domain controller : windows 2003 Server
Node 1 and node 2 have windows server 2012.
validation test passed. i want to create cluster for SQL Server Availability Group so there is no shared storage.
when create cluster getting error:
Pls guide what could be an issue and how to fix it.
thx

I've setup a server and installed the MS iSCSI Software Target 3.3 with 3 disks that I plan on using for a test Windows 2012 Cluster. I can connect to all 3 disks on each of the servers with no issues.
When I run the cluster validation I get a warning about the SCSI-3 reservations on the disks. My question is I thought I read somewhere that the MS iSCSI software did use the scsi-3 reservations.
here is the error:
"Test Disk 0 does not support SCSI-3 Persistent Reservations commands needed to
support clustered Storage Pools. Some storage devices require specific firmware
versions or settings to function properly with failover clusters. Please contact
your storage administrator or storage vendor to check the configuration of the
storage to allow it to function properly with failover clusters."
The Cluster does configure I was just looking to see if this can be set.
Hi
I have an issue on a two node cluster where the cluster validation fail on the List iSCSI Host Bus Adapters on one of the nodes only.
I looked at this post and it is similar http://social.technet.microsoft.com/Forums/en/winserverClustering/thread/5c73fefe-03d3-431b-a982-cc452838372e
The HW is a HP BL460c G7 with this component:
Manufacture: ServerEngines Model: OneConnect Drivername: be2iscsi Firmware Version: 2.102.517.7
The Cluster validation report says:
Gathering iSCSI Host Bus Adapter information for CNxxx.domain.local
An error occurred while executing the test.
There was an error getting information about the iSCSI controllers installed on the nodes.
There was an error retrieving information about the iSCSI host bus adapters from node 'CNxxx.domain.local'.
Invalid class
No matter what I do I cannot get Live migration to work with Server 2012.
I have a 3 node cluster. The cluster is fully validated. Quick migration works, but live migration does not work no matter what I try. The error I get is :
Live migration of 'Virtual Machine dom-test' failed.I have tried to follow the follow articles with various fixes reccommended, and nothing works.
http://blog.mpecsinc.ca/2010/03/nic-binding-order-on-server-core-or.html
I have built VM's from scratch on the cluster thinking maybe it was a problem with the fact I was importing VM's into the CSV, but same error.
I have restarted and rebooted every service and node time and time again
I have changed the NIC binding orders in the registry per one of the above blogs recommendations.
I have recreated the DNS A record for the cluster and set the permission to allow everyone to update it, etc.
I am at a complete loss here. I have tried every single thing I can think of.
Hi All,
I'm recieving event ID 4 everyday on my cluster nodes. I have a resource name,configured in cluster, which I used to login to as well. When i login with resource name ,it will automatically redirects to one of the cluster node where my resources are.
The kerberos client received a KRB_AP_ERR_MODIFIED error from the server %1. The target name used was %3. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named server accounts in the target realm (%2), and the client realm (%4). Please contact your system administrator.
As per the technet reference[ http://technet.microsoft.com/en-us/library/cc733987(WS.10).aspx] this happens when computer password changes during synch and other computer account has to be deleted. I can't do that in this ase because im using one of the resource itself which is very much valid.
Kindly suggest. Thanks in advance.
i've two physical servers, and storage.
i want to setup FailOver Cluster with these two nodes, but the the test fail.
I've setup the Node02 as Primary Domain Controller.
Node01 as Backup Domain Controller.
I've created this scenario with WinServer 2008 R2 and is working fine, but here it fails.
What can i do?
the error picture is attached.
thank you!

Hi,
Does anyone know how to resolve the following cluster errors (these occur approximately every 15 minutes).
EVENT ID 1228
Cluster network name resource 'Cluster Name' encountered an error enabling the network name on this node. The reason for the failure was:
'Unable to obtain a logon token'.
The error code was '1326'.
You may take the network name resource offline and online again to retry.
EVENT ID 1196
Cluster network name resource 'Cluster Name' failed registration of one or more associated DNS name(s) for the following reason:
The handle is invalid.
Ensure that the network adapters associated with dependent IP address resources are configured with at least one accessible DNS server.
We have 3 networks defined
Heartbeat - Cluster Use = Internal (No DNS configured)
Live Migration - Cluster Use = Disabled (No DNS configured)
Management - Cluster Use = Enabled (DNS configured)
We currently have a 6 node WS2008R2 Hyper-V cluster configured with the same network configuration with no issues.
