Cluster Aware Updating Scheduling

January 17, 2014, 2:49 am

I am having an issue with Cluster Aware Updating (CAU) on Server 2012 and Server 2012 R2. If I schedule self-updating and specify a time other than 03:00 (e.g. 07:00) in the wizard, when I get to the end of the wizard the confirmation page shows the schedule to be 03:00. if I click apply then the schedule does appear to be set to 03:00.The same behaviour occurs whether I am setting up CAU for the first time or editing an existing configuration. Thus it is not possible to schedule cluster aware updating for any time other than 03:00.

I am assuming that this is a bug, although I am open to suggestions if anyone else can think of a possible cause. I haven't found this mentioned anywhere online and I have been to MS Connect and Server 2012 is not listed as open for bugs. Has anybody else been able to reproduce this? Any idea how to report a bug if connect is closed?

I have two clusters, one on Server 2012 and one on 2012 R2 and I can reproduce on both:

OS Name    Microsoft Windows Server 2012 Datacenter
Version    6.2.9200 Build 9200

OS Name    Microsoft Windows Server 2012 R2 Datacenter
Version    6.3.9600 Build 9600

I am happy to supply further details if anyone is willing to help.

Thanks

Services do not auto start when Failover occurs

We have Windows 2008R2 Failover cluster as 2-node and majority disk configuration.   We have several SQL services set to Start/Manual.   When we perform a failover test, these services do not start.   Is that normal?

Also, we use CommVault to backup our Quorum database.   It creates GxClusPlugin instance in the Cluster.   This instance does not failover and fails.   Has anyone advice on this?

Thanks

Windows 2012 R2 Failover Cluster Hyper-V Invalid Class error when I'm trying to create VM

December 13, 2013, 2:06 am

Hi, in my test lab environment I created Windows 2012 R2 Failover Cluster with 4 Servers to get Hyper-V HA.


I had no issues with Windows 2008 R2 or Windows 2012 before in same setup (2 NIC, FC HBA, SAN storage), but this time I cannot creat VM using Failover Cluster console:


Roles - Vurtual Machines - New Virtual Machine - Select Host -> <ANY HOST>

I'm using default settings during VM creation (except setting path to VM manually to pont to desired disk).

IN progress I see disk creation and both VM configuration and .vhdx files on target disk, but after that I see "The Operation has failed. An error occured creating a New Virtual Machine. Invalid Class.



In fact I see virtual machine in Hyper-V Manager and it's fully functional, but not added to Failover Cluster Roles. When I use Configure Role - Virtual Machine to see eligible machines - it's not there.

Cluster Validation says that everything is OK.

I wasn't able to find anything in Eventllog(s) or %SYSTEMROOT%\Cluster as it was in Win2k8.

How should I troubleshoot this issue ?

Server 2012 R2 cluster error "An item with the same key has already been added"

Using the Configure Role option in Failover Cluster Manager on Server 2012 R2.  After selecting Virtual machines from the list, upon enumeration I receive the following error:

"An item with the same key has already been added"

I've looked at other solutions to this issue but they are unrelated.  Some mention firewall configuration and others network card guid on VM.  I can create a blank VM (no operating system and no NIC) with the same results.

This error appears even if there isn't a non-highly available VM to be converted to highly available (which i've run in the past and it will just enumerate nothing).

Tied to this error is the fact that when I do try to create a highly available virtual machine, the wizard completes but the virtual machine is created as non-highly available with no error given.  This is when I tried the Configure Role option and get the error listed above (assuming both are related to each other somehow).

hello,

i need to temporally exclude a node from an nlb.

May happen that a server is up and working but the web application i'm balancing is out of sinch with the same application in the others nodes.

Eg. some static variables are not the same of the same static variables of other nodes, because of a timeout, a write error and so on but the server is still working.

in this case i need to stop the server from nlb because the information in the web application is not in sinch with other nodes.

I need to prevent users from being serverd from this out to date server, untill it will became updated, but i need to do this programmatically

how can i do it?

Failover Cluster Policy question

Hello,

I am confuse with the following settings:

1. "If resource fails, attempt to restart on current node" once within 15 mintes ... no problem with this one.

2. "If restart is unsuccessful, fail over all resources in this serviceor application"

What is(are) the all recources in this service or application? Is it also the two drives in dependency?

is it also the file server share?

If YES this mean that the service (TSM) is the Manager of all other resources above, isn't it ?

Thanks,

SAS Cluster Storage 2012 R2

February 3, 2014, 3:10 am

Hello Everyone,

We are in the design process of building a new 2012 R2 Hyper environment having moved away from VMware.

My planned setup is

  • 2 x HP360 G8 Servers,
  • 1 x HP P2000 SAN,
  • Interdependent switches to mange the Hyper-V management (migration traffic etc.)

I have built a test environment to help me plan our new system, at the moment the storage for the test lab is local on each physical host.

When I build the main system i will be using a HP P2000 with SAS connections to both hosts, am i going about this the right way? 

My thoughts were to setup the P2000 with a ISCI target connected to a large volume, then connect to the target via the initiator on both of my Hyper-V hosts. 

Would this then enable me to create VM's on the shared (Clustered) storage? and allow me to move servers around etc.

Hope this makes sense :)

Thank you all in advance!

Hi,

I have come across a confusing question

One of our customer environment is having only one Windows 2008 Domain Controller in entrire FOrest and Domain. We know that its design problem which need to be corrected on priority. But i got struct in answering some of the questions as

1) If i am running Windows 2008 Failover Cluster for SQL DB, what is the level of dependency on my Domain/Domain Controller.

2) If Single Domain Controller which is there in environment is failed due to hardware or OS problem then Failover Cluster Server will get impacted immediately or it will run some time? If it run some time and fail later then what is the stage it will get failed actually.

Pls suggest if you know any of these points, its good discussion point as well.

WWW service is not able to start via Microsoft Failover Cluster generic service resource

Environment

Cluster Nodes = two

Cluster Nodes OS = Windows 2008R2

Application = IIS

Query

I created generic service resources of many windows services under Microsoft Failover Cluster and they are failing over successfully but when I create a generic service resource for WWW, then the WWW service is not able to online via Microsoft Failover Cluster. It stuck in online pending.

I have noticed two things.

1.) If the WWW service is set to manual and started at passive node and I manually restart the Active node then the WWW service successfully switch over to stand by/passive node. but if the WWW service is set tomanual and not started on stand by/Passive node then the WWW service is not failing over.

2.) if I kill the WWW service manually (as a test case) on Active Node via this command (taskkill /f /pid XXXX) then the WWW service failed and is not failing over to standby/passive node.

Any comment will be appreciated. Thanks. Zahid Haseeb.

Cluster Disk keeps going offline. Service or application failed

February 3, 2014, 5:59 am

We currently have 2 servers, both housing 3 VMs (6 nodes total).  2 Disk are used to house these VM's.  Cluster Disk 1 keeps going offline, which kicks 2 of our servers offline until we migrate the disk to another node (puts it into redirected mode).  We then have to restart the server to re-establish to connection to the cluster disk.  Digging around in event viewer, I saw the following:

Cluster resource 'Cluster Disk 2' in clustered service or application 'b0a21897-e59b-46c9-a495-273dc5ad2aea' failed.

Cluster physical disk resource 'Cluster Disk 2' cannot be brought online because the associated disk could not be found. The expected signature of the disk was '{92eb716c-6878-42ad-b7de-f3879d72e232}'. If the disk was replaced or restored, in the Failover Cluster Manager snap-in, you can use the Repair function (in the properties sheet for the disk) to repair the new or restored disk. If the disk will not be replaced, delete the associated disk resource.

The Cluster service failed to bring clustered service or application 'b0a21897-e59b-46c9-a495-273dc5ad2aea' 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.

I ran the cluster validation test and all seemed to check out except for Cluster Disk 1 and the two servers associated with this server, as shown below:

    Validating cluster resource Cluster Disk 2.

    This resource is marked with a state of 'Offline'. The functionality that this resource provides is not available while it is in the offline state. The resource may be put in this state by an administrator or program. It may also be a newly created resource which has not been put in the online state or the resource may be dependent on a resource that is not online. Resources can be brought online by choosing the 'Bring this resource online' action in Failover Cluster Manager.

      This resource is marked with a state of 'Failed' instead of 'Online'. This failed state indicates that the resource had a problem either coming online or had a failure while it was online. The event logs and cluster logs may have information that is helpful in identifying the cause of the failure.

All disks are housed on our SAN.  Any idea where I can start troubleshooting further?  Changing the signature of the disk or finding out which application is failing?  All help is greatly appreciated.

Failover cluster server - File Server role is clustered - Shadow copies do not seem to travel to other node when failing over

January 24, 2014, 5:06 am

Hi,

New to 2012 and implementing a clustered environment for our File Services role.  Have got to a point where I have successfully configured the Shadow copy settings.

Have a large (15tb) disk.  S:

Have a VSS drive (volume shadow copy drive) V:

Have successfully configured through Windows Explorer the Shadow copy settings.

Created dependencies in Failcover Cluster Server console whereby S: depends on V:

However, when I failover the resource and browse the Client Access Point share there are no entries under the "Previous Versions" tab. 

When I visit the S: drive in windows explorer and open the Shadow copy dialogue box, there are entries showing the times and dates of the shadow copies ran when on the original node.  So the disk knows about the shadow copies that were ran on the original node but the "previous versions" tab has no entries to display.

This is in a 2012 server (NOT R2 version).

Can anyone explain what might be the reason?  Do I have an "issue" or is this by design?

All help apprecieated!

I have two sever 2012 boxes with DHCP role installed on both. They are set up in a load balancing cluster.

How often do they sync or replicate to each other. I have noticed when I create a reservation on one, or a host gets a IP lease, it doesn't show up for a while on the other dhcp server.

How often to they sync?  Is there a way to configure how often they sync/replicate?

Hello,

      I have a couple Server 2008 R2 Hyper-V Host clusters with many VM's running on them. Is there a way I can introduce a Server 2012 R2 Hyper-V host server into each cluster, migrate the VM's to the Server 2012 R2 system and then be able to live migrate the VM's to another Server 2012 R2 Hyper-V host in another cluster?
