Hello
Can anyone tell me what a repair actually does to an offline cluster? I cannot find it in technet or msdn.
Thanks

Nodes randomly losing communication with cluster
We have a 6 node production cluster. We are on Windows Server 2008 R2 and SQL Server 2008 R2. At any time, a node will loss communication with the cluster causing every instance on that node to failover to other nodes. The event logs are very generic - event ids 1006 and 1335. We disabled tcp offloading, done nic driver updates, installed various patches (KB2524478, 2552040, 2685891, 2687741, 2754804), but its still happening. If anyone has any information that can help, please let me know. Here is what is happening in the cluster log at the time of the disconnect.

Cluster physical disk resource 'SQLVS01 Logs' cannot be brought online
Hello,
I was having SQL failover cluster farm contains 4 Servers, this week I expanded the farm to be 7 Servers.
the farm contains 3 Instance (VS01,VS02 and VS03), after adding the new servers i can move the instances (VS02 and VS03) to any of the new servers, but when trying to move Instance VS01 (the most important Instance) to any of thew servers I face the below error. I can only move this Instance within the Old servers (1.2.3.and 4) but i cannot move it to (5,6 and 7)
while as I said i can move the other instance to any of the servers even the new servers..
I already check some of the topics in the forum regarding the same issue but it could not help me
any help please
Error Message:
Cluster physical disk resource 'SQLVS01 Logs' cannot be brought online because the associated disk could not be found. The expected signature of the disk was 'B13B9D5A'. 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.

Windows 2008 R2 and SQL 2005 clustering
When I run cluster validation, I got the following warning "
The RegisterAllProviderIP property for network name 'Name: winclustername' is set to 1 For the current cluster configuration this value should be set to 0." The server has two NICs and one is public and another one is private (heartbeat)
should it be a concern?
Also, If I run ipconfig /all, I also see Microsoft failover cluster virtual adapter in addtion to public and private NICs, Microsoft failover cluster virtual adapter has 169.254.X.X private address, is this by design?
Thank you.

Windows 2008 Cluster question on using a new cluster drive source from shrinking existing disk
I have a two node Windows 2008 R2 enterprise SP1 cluster. It has a basic cluster setup of one (Q:)quorum disk and data disk (E:) which is 2.7tb is size. This cluster is connected to a shared Dell Disk array.
My question is can I safely shrink the 2.7tb drive down and carve out a disk size of 500gb from the same disk and use for a new cluster disk resource. We want to install Globalscape SFTP software on this new disk for use as a cluster resource.
Will this work without crashing the cluster.
Thanks,

Huge single storage pool for lots of VMs, or seperate storage pools for each VM
Background
Two identical 2008 R2 servers for running VMs with Failover Cluster (Hyper-V)
One IOmega NAS (old) with 15 VMs sharing one large (2 TB) clustered storage pool
One VNXe NAS (New) Nothing setup yet
I am getting ready to start exporting all of my VMs from our old SAN to our new SAN.
Is it better to create one huge clustered storage pool that will be shared between all the VMs, or would it be better to create separate smaller clustered storage spaces for each VM?
Thanks,
Brian

FailoverCount is not getting reset for QuorumResource in Windows2012 R2 failover clusters
Hi,
I have two-node failover cluster on windows server 2012 R2 with third party resource as quorum with typeNode and Disk Majority. on fault of quorum resource FOC is not failing over "Cluster Group" to other cluster node. Following log lines are seen in cluster log.

Is there a way to reset this FailoverCount ? When does FOC increments and resets this failovercount for a resource ?

Server 2012 Hyper-V Cluster Network Configuration
I have not been able to find any documentation that explicitly says if my network configuration is supported or not. It passes cluster validation but after a crash last weekend I am questioning it. Hopefully one of the experts here can chime in.
Here is our setup:
Server 2012 Hyper-V cluster, two nodes with a disk witness. Dell R520 Servers and a Dell Equalogic iSCSI SAN. CSV and witness disk are running on the SAN (on different volumes). Currently running four VMs, will expand to eight, possibly nine in the near future.
Each host has (all gigabit):
a 4-port NIC dedicated to the SAN using Dell mpio on its own subnet
a 4-port NIC team dedicated to the VM network
a 2-port NIC team for management, heartbeat and live migration
All are connected to a Dell two-switch stack with load balancing and failover at the switch level. All teams are using link aggregation and the SAN connections are using aggregation and jumbo frames.
My concern is having the live migration network on the same network team as management. I know this is not recommended but I have not seen this configuration listed as "not supported" either. Redundancy shouldn't be an issue with failover at the team and the switches. I am concerned with possible bottle-necking though.
If I were to add QoS to the 2-port team to cap the management and heartbeat bandwidth would that be enough? How much of a cap should I set?
Or should I break the team and create another network exclusively for live migration?
Or is the current configuration okay?

Nic Teaming and Clustering
I have 3 nodes in a cluster running server 2012. I have 2 ex4550 juniper switches connected via virtual chassis cables so they act as one switch. I have 2 10G Nic teams on each server. They are switch independent and I have one nic set for standby. The other team is used for my ISCSI connection and is set the same way.
I am getting a ton of errors on the cluster events, but everything seems to be working fine, well seems to be.
What would be the recommended network setup for connecting these 3 servers using 4 10G adapters to 2 ex4550 switches?
Thank you

Upgrading from Server 2008 R2 Core to 2012 R2
I am having a few problems with my 2008 R2 Core installation and am considering upgrading instead of just reinstalling which would be easier. My question is this; I have a three node failover cluster with Cluster shared volumes where the VHD and VM configs are stored on a NetApp SAN. I want to do a staged upgrade where I take two nodes out of the cluster and install fresh 2012 R2 full installs, configure the servers and set up the new cluster, once I have done that I can have a couple of hours downtime while I move the SAN over to the new cluster and then import all the machines into the new cluster.
The scenario works in my head but I was wondering if I am missing something. Also I am no iscsi guru so can someone give me a step by step guide to setup the MPIO and iscsi Section of the cluster.
We have a limited window to do this work as this will have to take place over the Christmas break which this year consists of 7 working days.
- Can I use the same cluster name or is it best to use a new one?
- Lastly should I remove the nodes properly leaving one node or just shutdown and let the cluster windge for a couple of days?
- Would I have to do any other config changes to the NetApp?

2012 R2 - First cluster, having issues creating Quorum witness disk
Its my first Server 2012 R2 Cluster and its based on a Dell VRTX server with shared storage.
I've created the cluster and I'm now trying to setup the Quorum witness disk.
In FCM Storage/Disks a 600mb disk is shown as online and I've called it Quorum.
In Win Disk Manager this disk shows as offline and reserved.
When I run the 'Configure Cluster Quorum Settings' wizard, pick 'Select the quorum witness', pick ' configure a disk witness' I get the error
No suitable disks exist in Available storage.
What am I missing?
Any help/advice/suggestions grateful appreciated :)

Cluster name resolves to the Node 1 address
Forgive me if this question is silly, I am new to clustering ---
Node 1 is a node on the cluster server, and the local are network card is statically assigned to the Node 1 address.The cluster server name DNS resolves to the Node1 address which is giving us trouble with the backup software client that needs to have a separate IP address for the cluster and the node.
If node1 is where the cluster was built, how can I assign a separate ip address to the same server and have it resolve to two different names?
I was not the tech who configured this box, and the cluster server itself has an IP address that is a different IP address than node 1 and Node 2, making three IP addresses for this server ---- where do I assign the cluster IP address without effecting the networking of the nodes?
thnx!

Cannot remove a Server 2012 DHCP failover relationship
Hi,
We created a test server (2012 std) and activated a dhcp server failover relationship with it. After having conducted various tests, this server was deleted. Unfortunately we discovered later that we couldn't remove the (now broken) dhcp failover relationship from the first server.
Whatever we try to do to remove the failover settings is honored with something like 'The DHCP service is not running on the target computer. Deconfigure failover failed'.
I have removed the dhcp role on both servers but when re-enabling it the relationship is still there...
Please help me with this....
What do we do to force removal of this broken DHCP relationship?

Server 2012 Hyper-V Cluster NIC Teaming Officially Supported?
Our current Hyper-V (Server 2012) setup has us using 3 NICs on each host and cluster node that are set up as external switches with each physical adapter set to a single VLAN (untagged.) What I would like to do is tag all 3 VLANs on those 3 switch ports then team them and set the teamed adapter up as a single external switch in Hyper-V. I realize that I will have to set each VM's NIC to go to whatever VLAN it belongs on but this is perfectly fine by me.
I have tested it on a standalone Hyper-V host and it works great. My question is about our cluster - I am wondering if it's officially supported by Microsoft. We just went through a 2-month long headache (which was never resolved) with premium support and I'd just like to know what we're getting in to before we spend more resources on it.
