Network Load Balancing not working with UDP traffic (Server 2012)

March 30, 2015, 1:57 am

Hi all,

I manage an application that receives traffic from mobile devices on cellular networks. The traffic is UDP. I have set up two x Server 2012 VMs to form part of a NLB cluster. Each server has a second NIC dedicated to NLB. The traffic is simply NATed from our firewalls to the virtual IP. When looking at the traffic using a packet sniffer, I can see the traffic being routed correctly to the virtual IP, but the problem is that the return traffic is sent from the IP address on the actual NIC. My application does not like the fact that the return traffic is coming from a different source IP. Is there any way to force the return traffic to also come from the virtual IP address?

Thanks!

Hi,

In my sofs cluster I have 3 networks LAN and SMB1 and SMB2

Now I have Excluded the LAN from my SOFS resource and this worked fine

$sofs = Get-ClusterResource "sofs1"

$net = Get-ClusterNetwork | ? name -Match "LAN"
Set-ClusterParameter -InputObject $sofs -Name ExcludeNetworks -Value $($net.Id)

But now I want to undo this. but it all failed So I need some help.

I used the  Set-ClusterParameter -InputObject $sofs -Name ExcludeNetworks -Value $($net.Id) -delete

Stopped the resource etc all failed.

How Can I undo the exclude network ?

Grt,

SQL Role Doesn't Failover to Active Node

I have build a 2-node Multi_Instance SQL Failover Cluster (Physical Machines) in a lab environment.  When I test the node in any manner (i.e. Pause Node/Drain Roles, Stop SQL Instance, etc.) all the storage moves to the Active Node, the DTC Moves, as well as the Quorum Disk.  However, I expect to see on the Active Node, in SQL Management Studio, 2 instances of SQL, and I am not seeing that.  If I fail Node A, as I said I can see in Failover Cluster Manager, Node B taking ownership of everything. However, in Node A, in SSMS the SQL instance just freezes up.  IN SSMS on Node B, it stays the same.

Why isn't the failed SQL Instance moving to the Active Node??  Have I configured something wrong somewhere??  I've validated the cluster and have no errors on it.

Hi,

I am trying to add third node to a Windows 2012 fail over cluster, but gets the following error.

The server 'DR.domain.com' could not be added to the cluster.
An error occurred while adding node 'DR.domain.com' to cluster 'domain-fc'.

Keyset does not exist

The User I am using to Add Node is Domain Admin, so it may not be a permission issue.

All nodes are Windows 2012 R2 VMs on Azure

NAS File Share as File Share Witness for Windows 2012 R2 Stretched Cluster

I've been unable to official documentation stating whether using a NAS file share (in my case, NetApp) as File Share Witness is supported for a Windows 2012 R2 Stretched Cluster. The cluster will support SQL 2012 AlwaysOn AGs. I've found unofficial blog posts from 3rd parties who have successfully configured a non-Windows file share as FSW, but need to know if this Microsoft supports this.

Thanks,

My company changed the default wsman URL Prefix for Winrm. As a consequence, we cannot access file shares on Failover Clustering. We get Event Error codes 142 and 49 under the Windows Remote Management  Event logs. Changing the URL Prefix back to wsman resolves our issue. Is there a way to resolve this issue keeping our changed URL Prefix?

Hi All

Currently I have a failover clustering configured containing 2 disks and both online

I'm in a process of testing failover with a specific app named SilverShield for SFTP

I've added the app as Generic Application and I've simulated the failover of the app and it seems that the app (.exe) fails over to the 2nd node, what I'm battling with is to connect to the SFTP site which I've created for testing using the same settings as it fails because it cannot reach the mentioned IP address

Thank you all in advance

SQL Cluster on Windows 2012 R2 Failover cluster and SQL 2014

March 19, 2015, 7:52 am

Hi,

This is crossposted in the sql server forum as well.  Mia culpa!

I've been watching stuff from teched. I want to install SQL server 2014, in cluster mode, on a Windows failover cluster that has 4 physical nodes and a number of VM's, on each physical node.  

All the clustering is done on 2012 R2.

I want to leverage a two node SQL cluster, installed on CSVs.  To get the most "rapid" failover, I get the impression (from teched) that I have to use "shared VHDX" files to house my database files and logs.  Is that correct? On the second node of the SQL cluster, do I attach the same database files and logs that the SQL node on the first cluster node is "writing" to, using shared VHDX?

Is there a document or video that fully explains installing the second node?

thanks for any help!  mark

Need to move SQL cluster nodes to different OU. Any gotchas??

March 31, 2015, 1:19 pm

I'm looking at an environment where all systems, desktops, laptops, and servers are placed into a container, AllSystems, instead of the default Computers container. The problem is that there has been no cleanup to where the servers get moved to their final OU, which in most cases has specific group policies applied. My concern in particular is towards SQL 2008 & 2012 cluster nodes which appear to have been pre-staged in this OU. Ideally I want these placed into a separate OU but can't remember if there are any consequences to moving cluster computer objects between OU's in a domain. I know the recommendation is to rebuild the cluster if it's being moved between domains but this isn't the case. I want to move these objects to a different OU. Can anyone confirm if this can be done with no impact to the environment? 

ANy responses appreciated.

Can you cluster two nodes from subnet A with the cluster itself residing in subnet B?

March 31, 2015, 2:38 pm

We have a situation in a cloud deployment where the servers are automatically provisioned through a cloud portal with IP addressed from subnet A. Because we require static IP for clustering, the static IP can only be provisioned from subnet B for use by the cluster.  Is it possible to create a cluster from the two nodes in subnet A from a cluster IP in subnet B?  I cannot find any mention of this particular network configuration for a Windows cluster.  We are using the cluster to support SQL Server 2012 AlwaysOn Availability Groups.

Upgrading Cluster To Windows Server 2012 R2

My previous thread was closed so here is a new one.

I have a 4 Hyper-V host failover cluster (R720s) running Windows Server 2012 Datacenter, which is connected to a SAN where the CSVs are stored. I have a 5th R720 server on which I have installed Windows Server 2012 R2 Datacenter from scratch. I have installed the Hyper-V and Failover Cluster roles on it as well. It is can see the SAN.

Questions:

1. To setup the Hyper-V virtual switch on the 5th server, should I join it to the existing Server 2012 Hyper-V failover cluster and create the virtual switch then? Or should I create the virtual switch on the 5th server, with the same settings as the virtual switch in the Hyper-V failover cluster, before adding it to the failover cluster?

2. Can I add the 5th server to the existing Hyper-V cluster, migrate virtual machines from Hyper-V host #1 to the 5th server, install Virtual Guest Services on the virtual machines which have been migrated to the 5th server, drain roles from Hyper-V host #1 and perform an in-place upgrade on Hyper-V host #1, once the in-place upgrade is complete, fail the roles back to Hyper-V host #1.

Please advise.

Thanks,

NLB on multiple VLAN

Hi,

Due to a migration of networks and server upgrade (out with 2003, in 2012). The 2003 are on a VLAN different than the future production VLAN for 2012. The idea would be on the new 2012 box, to have the cluster on the old VLAN and a cluster on the new VLAN. This is so we can staged the switch for the external applications going to the NLB.

Thus I'd like to know if it is possible:

* Have a Windows server be part of 2 different NLB - At the moment, trying that kinda crashes the first NLB were some servers are not reachable anymore

* Have an NLB with the different cluster IP on different VLAN

Thanks

Windows 2008 R2 Cluster - migrating data to new SAN storage - Detailed Steps?

April 1, 2015, 7:51 am
$
0

We have a project where some network storage is falling out of warranty and we need to move the data to new storage.  I have found separate guides for moving the quorum and replacing individual drives, but I can't find an all inclusive detailed step by step for this process, and I know this has to happen all the time.

What I am looking for is detailed instructions on moving all the data from their current san storage to new san storage, start to finish.  All server side, there is a separate storage team that will present the new storage.  I'll then have to install the multi-pathing driver; then I am looking for a guide that picks up at this point.

The real concern here is that this machine controls a critical production process and we don't have a proper set up with storage and everything to test with, so it's going to be a little nerve racking.

Thanks in advance for any info.

Windows Failover Cluster (Errors retrieving file shares)

I'm having an issue with Windows Failover Cluster with a Windows Server 2012 R2  machine. I have two cluster nodes (nodeA and nodeB). My issue is that when nodeA is the owner node, and I open failover cluster manager  <clusterName> >> roles >> <fileserver role> >> shares tab it will hang and say that it is loading, but this will occur infinitely. Although when I go to nodeB (not the owner node) and I go to shares it will show me all of the shares that I have. Next when I go to <clusterName> >> Nodes  >> click on Roles tab the information says "There were errors retrieving file shares."

Now when I switch the nobeB to the owner node, I cannot view the shares on that machine but can now view them on nodeA. 

We alse have a test network where I have recreated the machines, environment and the failover cluster to as close as the production network as I can except everything works great in the test network

Windows 2012R2 Core DC in clustered VM on Hyper-V 2012R2 FailoverCluster

April 1, 2015, 7:02 am

Hello Everybody,

Iam facing a strange behavior.

I have 2 sites with 2 distinct Failover Clusters in Windows Server 2012R2 Dtc Hyper-V using CSVs stored in a SAN. Each site has its physical domain controler.

Then I've virtualized and clustered a VM running a Windows Server 2012R2 Dtc core and promoted it as DC (on both sites). During a month no problem. But after I did the Windows updates in the VM I get an AD 1722 RPC error in the replication process.

I observed a strange behavior because my first virtualized DC (as clustered VM) is not able to ping the second virtualized DC (as a clustered VM) on the other site and vice and versa but is able to ping the rest of the networks.

To solve it I had to remove the both VMs from their respective failover cluster and I let it turn in the CSV volume and on one of the hypervisor of the failover cluster (on the both sites). After a reboot of the VMs the replication worked fine again.

I've read a lot of articles but I didn't found something recommending to not use DC as a clustered VM. As 2012R2 has a "AD-Less Cluster Bootstrapping" mode and having a physical DC running then normally it should work. Maybe I am wrong.

Please advise.

Hi there,

just set up a 2 node cluster with HCL listed hardware:
Windows Server 2012 R2 DC fully patched with latest Fujitsu MPIO DSM
Fujitsu Primergy RX300 S6 with 2 QLogic 2560 FC HBA each (latest drivers)
Fujitsu Eternus DX90S2 FC storage (latest firmware)

All volumes are visible/accessible by both nodes. Volumes are initialized, partitioned and NTFS formatted and set online for the 1st node. Volumes are offline for the 2nd node.

Running cluster validation tests ends up with error "Physical disk {...} does not have the inquiry data (SCSI page 83h VPD descriptor)". Additionally no disks are available as cluster resources.

Any idea welcome.

Thanks a lot.

Te.Be.

Urgent help about qourom disk please...

When I was installing SQL cluster service I chosed a wrong qourom disk for SQL service (Disk2)

after i installed SQL cluster service on my both nodes, i wanted to change the qourom disk from (Disk2) to (Disk5)

I thought it was easy, and here is what I have done:

I added a new disk to SQL service (Disk5), and I removed the old disk (Disk2)..

now when I brows from SQL management studio to attach my DB it directs me to (Disk2), which is not available on this cluster server anymore.

If you need attachments please let me know, i am preparing it now.
