How to move a cluster group & ressource in Microsoft Failover Cluster

Today I want to show you two ways to move the cluster ressource group and witness to another owner within the cluster. There are some scenarios where that could become necessary e.g. a planned maintenance.

To move the cluster resource is not that easy like moving a cluster shared volume. There is no option “move to best possible node” for the witness.


Witness Options


Cluster shared Volume options

So now there are two ways to move the Witness and cluster resources.

1. PowerShell

One you cluster node you run following command


2. Failover Cluster Manager Interface

For that you click on your cluster name and navigate on the right action panel to “More Actions”. There you have “Move Core Cluster Ressources”


Why you should plan your storage structure when working with clusters Part#1 Single Storage / Single Cluster

Hi everybody,

today I want to talk a bit about “why you should think about your storage structure when planning a cluster”.

Now most of you think “hey why thinking, I ask the storage guy to create a new LUN für me and thats it.”

Sorry guy’s theres the mistake. What if the storage guy provisions your new LUN on the same diskgroup like you others or on a full storage? What if the diskgroup or storage failes?

Within this post, you will get some of my personal best practices how to provison LUNs and cluster share volumes on Storages and diskgroups.

Let us start with an easy one.


What you should do is to create two disk groups. Yes you will lose some diskspace depending on the raid level but we are talking about redudancy and to minimize service outages. So a lose of diskspace shouldn’t be a problem.


Now you need to decide which RAID you want to use on your disk pool. Here it depends from storage to storage if you have SSD Disks as level 0 cache which most enterprises use, you can decide to use RAID 5 to enhance your capacity otherwise you should use RAID 10 to encrease your IO performance. NEVER use RAID 0!!!!

For the best storage capacity to perfomance relation for your storage, please talk to your storage vendor. He can tell you 🙂


Now you decide you LUNs that will provisioned on the Storage. Here you should use a designe which is logical for you. For me it depends on the cluster service I run. I will show you one of the most common and understandable ones.


At least comes the Windows Server Cluster Magic. Dependig on the cluster service you are running, you should now deploy the services and rolles on the different cluster shared volumes.

I will try to show it with the example Scale Out Fileserver and Hyper-V.

So that’s all for today, I hope that blogs helps you out a bit.

Clustered Storage Spaces on Dell JBODs Introduction

This information were collected together with my old team @Dell TechCenter and Dell Engineerin and one of my best friends Carsten Rachfahl – MVP Hyper-V.

Most of you know Storage Spaces already and you know how to use them for Scale out File Server but in the past there were some “issues” we have to fight with.

For all of you who need a recap for Storage Spaces, Scale out File Server and those stuff. I would highly suggest you Jose Barretos blog (Principal Program Manager at Microsoft).

One was, that you need SCSI Endclosure Service 3.x on your JBOD or direct attached SAS storage enclosures. There are a bunch of small vendors like dataon, who use this version in their systems but many of us have a preferred vendor like HP, EMC, NetApp, IBM or Dell.

Most of them do not support this SES version. Dell came up a few weeks ago with it’s first solution that supports SES 3.x and Storage Spaces. With the second they will come up in Q2 2014 with SES 3.x support.

First solution is the Dell PowerVault MD1200 and Dell PowerVault MD1220 together with the SAS 6 Gbit/sec HBA.

For Dell PV MD1200 Hardware Specs, you can find more details here.

For Dell PV MD1220 Hardware Specs, you can find more details here.

For Dell SAS 6 Gbit/Sec HBA, you can find more details here.

To see the supported designes please check out the guides on Dell Tech Center.

The second combination could be the Dell PowerVault MD3060e (Codename Roadking) together with LSI 9206-16e. There are no official information yet.
