2012 R2 Guest Cluster Network Failure

June 12, 2015, 7:11 am

We have a 2 node guest cluster (2012 R2) using a shared VHDX located on a CSV providing resilient File Server services and it seems to work well....most of the time.

We've had two instances lately where the File Server cluster has failed due to "network" issues where neither node can see each other and both are removed from the cluster. The problem is that we can't see any other VM reporting networking problems at the same time.

We did some Firmware and Driver updates on the physical nodes recently to resolve a known problem with VMQs an thought that our problems were solved. unfortunately we had a re-occurrence of the problem this morning so we seem to be back to the drawing board.

Has anyone else had similar problems with Guest Clusters in 2012 R2?

Cheers for now

Making NLB highly available

I get how to use NLB to cluster services such as web, ftp, etc. and I've successfully set it up before.  I'm now setting up an ADFS farm and I got to wondering how do I make NLB itself highly available?  If my lone NLB server were to fail, I lose access to all the clustered services.  I've googled around for the best answer, but the results are for how to create clusters the NLB will manage.

I am thinking the best answer is to failover cluster my NLB server?  When I search for failover cluster nlb, I just get results talking about the difference between the two types of clustering.  Can you failover cluster NLB?  If so, how?  If not, what is the proper way to make NLB highly available.

Thanks for your help in advance.

I built a cluster, and the CNO is created but the VCO and proper permissions of creating objects is not granted for that. Becasue I will create a Listener for SQL server HA, the question how can I automate when the CNO is created to have that permissions so that not to go through the manual process of adding CREATE OBJECT ,READ, etc tot he CNO?

Having multiple CAs share the same private key

April 28, 2015, 3:20 am

We are developing a system which implements an HA cluster across two separate geographical locations.
Each site will have several Windows Server 2012 machines and at least one DC, and we basically have to do a master-master replication between the two sites.
The entire system will be under a single domain.

We will be deploying AD CS since some of our sub-systems need certificates,
but we want to limit the variety certificate to just one (i.e. we want all CAs to issue identical certificates).
To do that, we have to setup AD CS so that all the DCs (both intra-site and inter-site) share the same private key.
Is it possible to have all DCs in a domain to share a single private key?

This article on TechNet suggests that we can do it within a cluster,
https://technet.microsoft.com/en-us/library/cc742450%28v=ws.10%29.aspx
but we are not sure if we can do it across different sites.

Any advice and comments are highly appreciated.

Quorum Failover Cluster - Windows Server 2008 r2

Hello,

I have a fileserver cluster environment with two members, NODEA and NODEB. The cluster name is FS01.

We have the quorum disk in the cluster that is active on owner node. 

My question is, when we perform the failover of cluster resources for NODEB, the quorum disk must migrate to NODEB too? If the quorum disk is not migrated instantly, that means we have a problem in the cluster?

Another question is, my cluster is making failover of resources with a certain frequency, it is possible to detect the cause? it is possible to increase the cluster threeshould?

Thank you

Hello Team,

Greetings for the day!

I have 2 Windows server 2012, with Network Load Balancing role enabled on it, on both the server sharepoint 2010 R2 (Sharepoint Farm) is installed. I have enabled Network load balancer, with total of 5 IPS assigned between those 2 server.

The sharepoint site is working very slow some time (1min 30 sec), and sometime it respond very quickly(10 sec).

I have verified both the server performance which is more than good.

Me not sure what can I troubleshoot it further, I am also not sure how to check which server the request is going.

Help me coming out of this situation and optimize the performance.

The cluster Resource Hosting Subsystem (RHS) process was terminated and will be restarted

Server 2012 R2 on beefy PowerEdge R720 dual cluster

CAU worked fine on my cluster long time ago when there was few simple VMs.

As the setup got a big more complicated (more VMs with more disks, more backend iSCSI storage, some VMs in cluster setup), CAU just does not work reliable at all.

So this time I was doing hosts WU by hand (migrated VMs to Host A, updated Host B, restarted, updated again as some updated failed, restarted fresh again, Resume/Do not fail back roles (to be on the safe side...)

Then I selected some running VMs on Host A & Live Migration them back to Host B... at which point Host B (one just updated & freshly rebooted) thrown a fit & killed all VMs that were selected to be moved to it...

"The cluster Resource Hosting Subsystem (RHS) process was terminated and will be restarted. This is typically associated with cluster health detection and recovery of a resource. Refer to the System event log to determine which resource and resource DLL is causing the issue."

Cluster service did restart & did bring the machines up, but that is less then user friendly, had to select them one more time to migrate (and this time they did)

But the whole solution just feels not like Enterprise product (in fact it would not be acceptable even for home use)

Do not expect any miracle solution, but if anybody has any experience to chip in, it would be appreciated

Processor Information for Lizard

I've just put together a small cluster, with all nodes using Intel E5-2665 cpu's, and all running server 2012 R2. I'm trying to benchmark it using Lizard, but it is asking for information on the CPU.

"To calculate the theoretical efficiency of your HPC cluster, Lizard needs to determine the number of floating-point operations per clock cycle that each core in the processor of the head node of your HPC cluster is capable of performing, and uses that information as a reference for the rest of the compute nodes in your cluster. If Lizard cannot automatically determine this information about the processor, you will be required to provide it."

When I look here (https://msdn.microsoft.com/en-us/library/ee146526(v=ws.10).aspx) on the Microsoft help page, it just says look at the manufacturers website. I've done that and can't see the information I need.

Does anyone know where to look for the necessary info please?

Many thanks.

Long time of creating VM checkpoint on file share storage

Hi,

Why VM checkpoint creating time so long ~6min  on file share storage ?

RAM of VM 10Gb

Same VM on local disk checkpoint creating time <3s

When I reduce RAM size of VM to 1Gb - checkpoint time <1min

When checkpoint was creating I looked to file share storage server and Hyper-v server performance monitor and found that disk and network activity was loaded as usual.

Thanks

Node being removed from Windows Server 2012 R2 cluster

Windows Server 2012 R2 multi-site cluster with 5 nodes.  Node 1 (at the main site) fails multiple times a day with the same issue in the cluster log as shown below.  All the other nodes log missed heartbeats.  If it were latency I would expect all nodes to fail at one point or another but node1 is the only one that drops out.  The servers are all the same model with the same drivers.  The switch ports show no errors.  I see no UDP dropped packates in perfmon.  I have checked everything in the following blog: http://blogs.technet.com/b/askcore/archive/2012/02/08/having-a-problem-with-nodes-being-removed-from-active-failover-cluster-membership.aspx and this one: http://blogs.technet.com/b/askcore/archive/2012/07/09/having-a-problem-with-nodes-being-removed-from-active-failover-cluster-membership.aspx.

I do not want to change the cluster delay and threshold values except as a last resort.  The ping times between sites is down in the 3-5ms range even during the issue which is well below the recommended range.

Does anyone know what causes the failure that seems to kick off the issue?

CSV - System Volume Information Problem

Hi,

Not sure if this is the correct place to ask my question...

We are having an issue with the System Volume Information on one of our Cluster Shared Volumes growing to a large size.
It currently sits at 598GB. 

We have two hosts - Three volumes, C:\ClusterStorage\ - Volume1 - Volume2 and Volume3.

The issue only appears to be happening on Volume2 in the System Volume Information folder and not sure what's causing it.

I have checked Shadow Copies on both hosts and all are disabled.

I am hoping someone could point me in the direction to figure out what is causing the consumption of lots of space.


We run a daily windows backup on each host to separate USB drives also.

Thanks,
Adam

Hello,

Nice opportunity for a good laugh here..potentially.

Looking to deploy an SOFS and HV cluster over the coming summer. Going through the network configuration and have come up with the following (link to image below). Each cluster is comprised of 2 nodes, so nothing too heavy on the network side of things. 

SOFS cluster will utilise SMB 3.0 app shares, on a JBOD.

Would welcome suggestions/bad mistakes/judgement calls..

Live Migration of Server 2012 R2 Remote Desktop Server Disconnects Users

June 16, 2015, 3:23 am

Hi. I have a 2 node Server 2012 R2 failover cluster and amongst the services running on this cluster is a Server 2012 R2 remote desktop server (this has the session host, web access, licensing and connection broker roles). When I move the 2012 R2 remote desktop server to the other cluster node using live migration, users are disconnected from RDS and get an error to say "failed to reconnect session". Users can immediately, manually reinitiate their connection to the server.

I have other 2012 R2 servers running on this cluster, which don't have the remote desktop services roles installed, and these servers do not exhibit the same behaviour of disconnecting users after a live migration.

Have found only a few references to similar issues on a couple of other TechNet discussions, but no resolution etc...

I'm guessing this is not expected behaviour and there is some kind of configuration issues somewhere?

Cluster Shared Volume error after server not shutting down properly

Hi,
We have two IBM X240 servers ( we call it server A and server B) connecting to IBM disk system:V3700 via fibre HBA.

The both servers are installing windows 2012 R2.

We have implemented VM cluster and everything is working well.

Last week this two server is down due to power shortage in my server room.

After turning on the  server A, it will come out the below error:

Windows failed to start, a recent hardware or software change might be cause.
File: \windows\system32\drivers\msdsm.sys
status: 0xc0000017
Info:the operation system could't be loaded because a critical system drive is missing or contain errors.

After using the Last Good Configuration, we can log in to the system and turn on the clustered virtual machine.

it seems everything is fine now.

So i go and start the server B and log in to the system using the same method with server A.

I found all the VM will be shut down or running error due to Cluster Shared Volume error.

Refer to below some errors captured from system system logs.

* Event 5142, Cluster Shared Volume 'Volume7' ('Cluster Disk 10') is no longer accessible from this cluster node because of error '(1460)'. Please troubleshoot this node's connectivity to the storage device and network connectivity.

* Event 5120,Cluster Shared Volume 'Volume3' ('Cluster Disk 4') has entered a paused state because of '(c00000be)'. All I/O will temporarily be queued until a path to the volume is reestablished.

Now we only can turn on only one server and shut down another server, if i turn on both server, the error will come out again & the server will go down.

Any suggestion or need me provide more information.

Thanks.
