Microsoft Failover Cluster 2012 R2

Hi,

I am migrating from windows file server cluster 2008 to 2012 R2. gradually, I managed to migrated 3 out of 6 file server roles using copy cluster role wizard in 2012 R2.

but i got below error message after the wizard examins source cluster and give you the option to select the remaining any of the other 3 roles on 2008 cluster. no matter what i do it immediately give this error:

"The Operation has failed. Failed to determine if the select disks page is required.

Error Code:0x80070490

Element not found"

I restarted the cluster services on both source and destination cluster and tried with same results. Restarted the whole servers but in vain.

Any Idea what could be the cause? and how to continue migration?

is there any powershell cmdlet to do the same?

TIA

I need create a hyper-v cluster on this hardware:

1) Host 1

2) Host 2

3) Fileserver

4) SAN

5) Switch 1 Gb/s

6) Windows server 2012 R2 standard - 3 License

Scale-out File server approach for the files server, but we don't have VMM license.

Without VMM can'not add storage to the Hyper-V cluster.

What is the best approach in my situation?

S2D Storage Spaces Direct Server 2016 Datacenter

Hello and Thank All for being here. I am novice and having issues and not sure what else to try. first technet post.

Using Chelsio cards and Dell PowerEdge R720’s I have a 2 node S2D setup with 1 VM on each node, non-production setup. I am forcing Node 1 cluster service to fail and seeing VM1 go unmonitored and live migrate failover to Node 2, good stuff. I can see a file copy seem to go into a ‘paused’ state then complete and my RDP session on VM is only broken temporarily when I’m forcing the cluster service stopped on a node (RDP does reconnect after about 10-20 seconds butwould like to not see RDP lose connection if possible and have been playing with (get-cluster).ResiliencyDefaultPeriod = 30 settings, any additional advise there is appreciated as well, not sure if this is related to my issue).

I will see the live migrate failover occur and look ok. I’ll wait and check for a job to be running by issuing ‘get-storagejob’ on both servers. When the disk is clean and healthy I’ll live migrate the VM to its original Node to set up next test, when I’m doing that I’m getting some errors I’m able to work around but unable to resolve right now.

Live migration failover seems to work despite the RDP session loss at this time. Today I’m seeing both nodes with its VM (that actually failed over successfully in test) in a ‘paused’ state in Hyper V manager although the same VM is actually running and online on the Node it failed over to. This ‘paused’ VM seems to be an issue when failing back to its owner. I’m able to reboot and restart services and finally get it to live migrate back. This isn’t practical for production use and probably not working as it should. I appreciate any assistance on this and look forward to hearing any replies.

For what it’s worth I think I have done ‘quick migration’ when ‘live migration’ failed. Not sure what the difference is or why it worked. If anyone can explain I do appreciate it. If you help me fix this I’ll take you airboating on Lake Okeechobee and catch an alligator or some bullfrogs.

Some messages logged are below, there are many. Please direct me to what you’d like to see.

Event ID: 21127 - 'Virtual Machine Configuration VM1' failed to unregister the virtual machine configuration during the initialization of the resource: The wait operation timed out. (0x00000102).

Event ID 21129 -'Virtual Machine VM1' failed to stop the virtual machine during the resource initialization: The wait operation timed out. (0x00000102).

Some fix I read suggests removing configuration in GUI but not saying why this happens or how to resolve it

I'm looking to understand what people consider "best practice" for configuring networking in a Hyper-V Failover Cluster. There does not seem to be a complete article from Microsoft based on Windows Server 2012 R2 that includes all the details. There is also loads of content on blogs etc that give conflicting advice. 

NIC Teaming (on what kinds of interfaces)

NIC Team (method and configuration)

NIC Bind Orders

Service Bindings on NIC Teams/Interfaces

Network Prioritization 

Anything else you may think it useful.

Server 2012 R2 keeps crashing and lossing a month of Existence

Hi all,

I have a  Windows Server 2012 R2 in a cluster which keeps crashing and upon starting up it is back to a point in time 15th May 2017. Even if I manually restart this will occur. Any data or apps installed after 15 May 2017 are gone. From my investigations windows update had been installed at this time 15th May. The server starts and first entries in the event viewer are for the 15th May. System time is ok after reboot. While starting up it displays windows is finishing updates every time. It is stuck in this loop. There is no snapshots/checkpoints. I have used DSIM to try and repair. I've ran disk clean up to clean-up windows updates. I removed windows updates installed on the 15th May. Anyone else ever seen this behaviour? Hope someone can help.

WSFC stopped to communicate outside primary subnet

Hi All,

I have really strange issue happened yesterday and was take me a few ours to troubleshoot this with the networking team. My WSFC along with SQL AGL stopped to communicate outside primary subnet (communication was OK between two nodes on the same site, WSFC, AGL and Windows server file share witness). My network team detected as the requests successfully reaching WSFC and  SQL AGL however was no responses back from it. We did failover between sites and AD resolving a new IP for both however was still no luck to reach it. The resolution was to remove Virtual IPs for each site and add them back in.

overview:

Site A

Node 1:

IP: 10.10.10.11

Mask: 255.255.255.0

DG: 10.10.10.1

Node 2:

IP: 10.10.10.12

Mask: 255.255.255.0

DG: 10.10.10.1

Site B

Node 3:

IP: 10.10.20.11

Mask: 255.255.255.0

DG: 10.10.20.1

Node 4:

IP: 10.10.20.12

Mask: 255.255.255.0

DG: 10.10.10.1

WSFC 10.10.10.22 or 10.10.20.22

SQL AGL 10.10.10.23 or 10.10.20.23

IIS Load balancing

My question may be off topic, but as i finish my course with these clustered database, i'll get my hand dirty, start writing some code, which i assume, after some time, it become a high traffic website, if it goes well. at begin i'll start with three server for my replication, but if the primary/master goes down, then my IIS will go down, and as the IIS is the only client of the replica set, so there is no point in having multiple server and replication. what i was thinking, is how to point user to available IIS with also maybe lowest traffic? 

so if user X, point at abc.com then it get redirect to the IIS of one of the servers that can response his/her requests. not just the server that may be down at that time? Do i need to also setup a DNS configuration, or the Domain's Panel will let me do that?

What should i know? where can i find the resources?

My OS environment is Win 2012 R2.  I have been running in circles and nothing seems to work, and no post that I can find has troubleshot this on Win2012R2 \ SQL Server 2016.   I am using Availability Groups, and it was working just fine, until I installed patches on one node and not the other, which messed up the cluster.  Can  someone please help?

Windows Server 2012.

On trying to enable CauCluster role i get the following error:

Add-CauClusterRole : Cluster-Aware Updating (CAU) has detected that Windows Firewall is enabled on node "ClusterServer".
However CAU is unable to enable the 'Remote Shutdown' firewall rule group. This will prevent CAU from restarting the
node as necessary after updates are installed. Check if Group Policy settings are used to configure Windows Firewall
and adjust the policy settings to enable the firewall rule group.

I have checked the firewall and the "Inbound Rule for remote Shutdown" Group:RemoteShutdown is already enabled on both my servers.

Any Advise?

Windows server 2016 failover cluster networking

January 26, 2018, 4:33 am

Hello good people,

I need to understand something.

I have two servers App01 and App02 in a WSFC,Node App01 has private IP say 10.2.0.12 and App02 has 10.2.0.13 while the cluster IP is 10.2.0.14. Everything works fine.

Now we have to NAT the cluster so the cluster can access another server/service outside our network.

What we want is to use the cluster IP for NATting, say 41.50.12.33 with 10.2.0.14 so anyone from outside can reach the cluster by the 41.50.12.33 and packets from our network to be sent by cluster IP.

Now this has been done and we can reach the cluster from outside, the only issue is that packets from our organization are sent outside with the active node IP and node the cluster IP. This lead to a problem because in our NAT configuration, only the cluster IP is recognized in the tunneling configuration. 

Is there any configuration to be done for packets to be sent with cluster IP and not node IP?

Thanks and regards.

Heartbeat in Windows Server 2016 Failover Clustering

June 8, 2018, 2:43 am

Hi,

Good day! :)

I'm trying to figure out the importance of private network in windows clustering. From what I've searched, private network is for heartbeat. Is it necessary to have dedicated link for heartbeat?

I have already set up windows clustering with 2 nodes. I have public and private network. I assume private network is for the heartbeat. In my testing I remove private and public network link connection of node 1 and as a result, service failover to node 2 without any problem. And then I reconnect only the public network connection of node 1. Then I remove the public network connection of node 2 and service failover to node 1 without any issues (private network still not connected).

I tried to get traces using windump and I noticed that public network also has heartbeat packets. Does that mean that WSFC is possible even without private network dedicated for heartbeat?

I hope you could help me with this.

Thank you.
