Server 2012 R2 Running Failover cluster role on Domain Controler

I absolutely need to have Domain controller running failover Cluster node,
we have been doing it in 2008r2 and there are documents from Microsoft stating it is possible but not recommended
but the document is for 2012, I am running 2012r2
I can install failover clusting role on a 2012r2 server and from a Member node install the cluster but when I need to add the nodes that are Domain controller they thry to add but then they timeout after 5 minutes, then they delete the node that was try
to add and clean up
I have tried the CNO record and try to install DC befor and after Cluster role,
HELP
thx

Not supported, see this KB:
http://support.microsoft.com/kb/281662
Run the DC in a virtual machine, and then put it on top of the cluster.
Thanks!

Good device to put Instance root directory on a SQL Server 2012 Always On Failover Cluster ?

Hello, I'm currently testing SQL Server 2012 AlwaysOn Failover Cluster.
I wonder if I installed it correctly : I installed the software on both server with the instance root directory set to a directory on a cluster shared module.
The reason why I'm not sure is because, when I wanted to upgrade from SP1 to SP2, I wanted to do it first on the passive node, but it failed for most of the components it had to upgrade. So I first upgraded the active node then failover and upgraded the
newly active node.
I installed SQL Server this way because our system admins don't like us to install in on C:\ for their own reasons (maybe backup, or something ...)
I'm pretty sure there is something wrong. What's your point ?
Thanks in advance.

>I wonder if I installed it correctly : I installed the software on both server with the instance root directory set to a directory on a cluster shared module.
Nope.
SQL Server 2012 and earlier don't support data files on CSV volumes (SQL 2014 does).
And for any version of SQL Server the SQL Server instance directory should not be on a clustered disk. The Installation is local to each node, so should be on a non-clustered disk. It may be supported to put the instances in different locations
on the same clustered disk, but I wouldn't recommend it.
Installing the SQL Binaries on C:\ is fine. If you have another local volume you can also install them there.

Server 2008 Hyper-V Failover Cluster Error on Domain Controller Reboot

I am pretty new to Hyper-V virtual but I have 2 Hyper-V Clusters, each with 2 Nodes and a SAN, 1 Physical Domain Controller for failover cluster management and 1 virtual domain controller as backup. All is running well, no issues. I installed
windows updates on the physical DC and upon reboot, got an error 5120 on cluster 2 that says "Cluster Shared Volume 'Volume1' ('Cluster Disk 1') is no longer available on this node because of 'STATUS_CONNECTION_DISCONNECTED(c000020c)'. All I/O will
temporarily be queued until a path to the volume is reestablished. It pointed to the 2nd node in that cluster as being the issue but when I look at it, it is online and all healthy so I don't understand why the error was triggered and if the DC would
go down for a failure, would that node not be able to access the CSV permanently.
Appreciate any help anyone can provide.

Hi mtnbikediver,
In theory, if you has the correct configuration of cluster the DC restart will not cause the CSV down, does your shared storage installed on your DC? Did you run
the cluster validation before you install the cluster? We strongly recommend you run the cluster validation before you build the cluster, same time please install the recommend update of 2008 cluster first.

http://support.microsoft.com/kb/957311
I found a similar scenario issue the DC restart will effect the cluster network name resource offline, but it is for 2008R2.
Cluster network name resource cannot be brought online when one of the domain controllers is partly down in Windows Server 2008 R2

Requirements for similar hardware in a 2012 Hyper-V failover cluster?

Simple question:
How similar does the hardware have to be on the host servers in a Windows Server 2012 Hyper-V failover cluster?
We have 6 dell servers that we are hoping to use for building a Windows 2012 Hyper-V cluster.
As I recall from our existing 2-host Hyper-V cluster, which is running on 2008 R2, there are fairly harsh demands in the cluster validation wizard with regard to similarity of hardware. So I am wondering if it will work?
The servers in question are 3 x R620, 2 x T410 and 1 x T610 Dell servers. So 3 x 12th generation servers and 3 x 11th generation servers
The servers all use Intel CPUs:
R620: Xeon E5-2670/2680
T410/610: Xeon X5650
and broadcom NICs:
T610: Broadcom 5709c
2 x T410: Broadcom 5716c
3 x R620: Broadcom 5720
Windows 2012 is supported by Dell on all the servers.
Shared storage will be on an SMB3 file share.

Shared storage will be on an SMB3 file share.
You'll be fine with a listed config no need to have identical machines. The only thing I'd try to change is use the same NICs all-around if possible.
P.S. Make sure you understand SMB share is a single point of failure unless SoFS or "old skool" NAS failover is configured. But it adds latency so using shared storage
directly w/o a file transport is FASTER and CHEAPER.

Server 2012 R2 Hyper-V Cluster, VM blue screens after migration between nodes.

I currently have a two node Server 2012 R2 Hyper-v Cluster (fully patched) with a Windows Server 2012 R2 Iscsi target.
The VMs run fine all day long, but when I try to do a live/quick migration the VM blue screens after about 20 minutes. The blue reports back about a “Critical_Structure_Corruption”.
I’m being to think it might be down to CPU, as one system has an E-2640v2 and the other one has an E5-2670v3. Should I be able to migrate between these two systems with these type of CPU?
Tim

Sorry Tim, is that all 50 blue screen if live migrated?
Are they all on the latest integration services? Does a cluster validation complete successfully? Are the hosts patched to the same level?
The fact that if you power them off then migrate them and they boot fine, does point to a processor incompatibility and the memory BIN file is not accepted on the new host.
Bit of a long shot but the only other thing I can think of off the top of my head if the compatibility option is checked, is checking the location of the BIN file when the VM is running to make sure its in the same place as the VHD\VHDX in the
CSV storage where the VM is located and not on the local host somewhere like C:\program data\.... that is stopping it being migrated to the new host when the VM is live migrated.

Hyper-V Server 2012, CAU, Unable to drain roles

Hi,
I have a 2 node failover cluster running Hyper-V Server 2012. Draining one of the nodes for CAU fails without any obvious errors logged. All of the VMs live migrate successfully, after three re-tries node drain fails, the node leaves maintenance
mode, and VMs live migrate back to their original locations. I've reviewed all the event logs on each server and I'm stumped.
All of the networks and disks are in an UP status. CSVs are not redirected and they are all owned by the host having difficulty draining roles.
It seems the best thing to do is to run the cluster validation tests, specifically the storage tests. I won't have a maintenance window to bring
everything down for quite a while however and some of the storage tests are known to be disruptive.
Does anyone have a suggestion?
Thank you

SQL 2012 installation for Failover Cluster failed

While installation of SQL 2012 on FOC validation fails on "Database Engine configuration" page with following error:
The volume that contains SQL Server data directory g:\MSSQL11.MSSQLSERVER\MSSQL\DATA does not belong to the cluster group.
Want to know how does SQL installation wizard queries volumes configured with Failover Cluster. does it:
- Enumerate "Physical Disk" resources in FOC
- does it enumerate all Storage Class resources in FOC for getting the volume list
- or it depends on WMI (Win32_Volume) to get volumes ?
The wizard correctly discovers volume g:\ in its FOC group on "Cluster Resource Group" and "Cluster Disk Selection" page. but gives the error on Database configuration page.
Any help in this would be appreciated.
Thanks in advance

Hi I have a 4 node Windows server 2012 Hyper-V cluster. When I try to run a cluster validation report, everything else is fine but it fails at validate the Operating System Installation Option step. I did some research but couldn't really find any solution.
Anyone knows how to pass this test? Thanks.
Here's the error I get when run the test:
An error occurred while executing the test.
The operation has failed. An error occurred while getting the operating system installation option for node "server1"

Server 2012 R2 Hyper-V Cluster - Losing connectivity to vLANs

Hi Everybody,
I am experiencing a strange issue with a Server 2012 R2 Hypervisor. There are two physical NICs teamed (one from on-board and one from expansion board), this team is assigned to a hyper-v virtual switch, there are four virtual network adapters
assigned to the switch (Backend, Heartbeat, Management & CSV/Live Migration).
The server has been running without issue for months but, all of a sudden has started to lose connectivity to the Backend and Heartbeat. The loss of connection only occurs once VMs are hosted on the server and it doesn't happen immediately, it can take
anywhere from 12 hours to several days.
There are no errors on the NICs or vNICs themselves and the configuration is intact. Once connectivity is lost to the Backend and Heartbeat, it remains that way and it seems the only solution so far is to reboot the server. Hardware diagnostics have been
run and revealed no issues. There are no useful events in event viewer, the alerts relate to the loss of connection to the cluster as a result of connectivity being lost on the Backend and Heartbeat.
I have 6 other hypervisors with the same network configuration that are performing without issue so, I don't believe the problem is the configuration. The only difference is the hypervisor that has the problems is a Dell Poweredge R620 and the other 6 are
Dell PowerEdge R610s.
Can anyone advise what might be the cause of these issues or, any event logging to enable that might help isolate where the issue lies.

Sorry Tim, is that all 50 blue screen if live migrated?

Add IPv6 to a running failover cluster

Hi
I have a sql failover cluster running win2k8 R2 and SQL 2008 it was built around IPv4 the instance listens on IPv4 cluster IP address ( virtual IP)
I rescently got a request that there will be servers running in pure IPv6 networks and the need to be able to talk directly to the database using IPv6 that where I need to add a cluster IPv6.
The database is the backend for our backup server and it cannot be taken offline or allow a downtime of more than 30 minutes so rebuilding the cluster is out of questions
So my question how do I go by and add the IPv6 cluster address alongside the IPv4, I am not reffering to an IPv6 Resource.
Any suggestions will be very appreciated
Regards

Hello,
Please try to configure the NIC on the nodes for IPv6 and make sure the Host Record (A) has been created for IPv6 on the DNS server. I think that’s all you need.
I am sorry for the late response, I did not notice the thread on the forum.
Hope this helps.

Hi,
Check if SQL Server service is running fine. I doubt you may have changed the user account password used for SQL Server service. After restarting the machine, you also need to update the user account of SQL Server service in Configuration
Manager. Re-type the user account name and password under Log on tab and see how it helps.

Microsoft // Winlogon 4005 (The Windows logon process has unexpectedly terminated) on one Windows Server 2012 VM with working RDS roles installed

Hello experts,
I have deployed all essential RDS roles and features on one Windows Server 2012 Virtual Machine
a few months ago and I recently ran into issues with users not being able to access it through RDP all of a sudden after entering credentials successfully.
Every time that happens I get an event ID Winlogon 4005 (The Windows logon process has unexpectedly
terminated). I am also receiving but not all the time event ID 6000 and 6003 referring to being unable to handle critical or normal events from AUinstallAgent.
Any help on this problem would be greatly appreciated.
Thank you in advance for your support.

SQL Server 2012 stops running after setup files are copied.

SQL Server 2012 setup stops running after setup files are copied.
I've experiencing the same issue on two different machines. Both are 64 bit running Server 2008.
On both of them I tried installing using the files from the ISO. I initially used winzip to extract the files. The setup was running fine, but the SQL Server engine had an error when it installed. Then using the Add/Remove programs i uninstalled all of the
SQL Server 2012 applications, including the setup files.
Now when i try to install using the "New SQL Server stand-alone..." wizard it will copy the setup files and then the wizard never comes back. I've tried mounting the ISO, extracting with winrar, Burning the ISO to a dvd and downloading the 3 files. I also
tried mounting ISO of the version that was just recently released. I run into the same issue with all of them.
Thanks for the help.

can you try
setup.exe
/Action=install /x86 /UpdateEnabled=false
If this doesn't work please use below FAQ to locate and upload SQL Server setup logss.

Server 2012 R2 DHCP Failover - Hot Standby clients not renewing with standby server

In my test network I have a pair of Server 2012 R2 DHCP servers setup for Hot Standby and they will successfully service a client request for a new request.
What I am seeing is that when I test failover the clients will not renew with the Standby server. I have to release first and then renew.
When both DHCP servers are up the state is normal and replication of configuration from the Active to Standby is working. As far as I can tell it is configured correctly.
MaxClientLeadTime is 10 minutes.
StateSwitchInterval is 10 minutes.
AutoStateTransition is set to True.
Adding that manual renews fail with a message stating that it was unable to contact the dhcp server. However if I wait for the lease to expire/auto-renew the dhcp server does indeed change to the standby. Once the primary server comes back up and the state
returns to normal I am able to manually renew.
thanks in advance

Hi,
For test, we let the active DHCP down and the standby DHCP server will take place. But when we renew an IP, client send unicast to the former DHCP
server. That’s why the first request failed.
At 7/8 of the scope lease time, the client moves into a REBINDING state and broadcasts a lease renewal request.
For more information please refer to:

Windows 8 and Server 2012. Not detecting network is a domain.

Hi Guys,
I hope I have posted this to the correct forum.
I have 2 x Windows 8 PCs that do not detect that they are connected to a domain (network location awareness not working). I can join them to the domain but they still don't recognise the network as a domain. Instead they identify it as "private".
Other PCs on the network (Win XP and Win 7) work prefectly, just the windows 8 machines don't work.
Also, when I do join them to domain I also receive this message.
"changing the Primary Domain DNS name of this computer to "" failed. The name will remain xxxx.local. The error was: the specified domain either does not exist or could not be contacted. "
I have tried the following
- DHCP and DNS has being tried both as static and dynamic (can ping DNS server which is the domain controller Windows Server 2012) .
- Updated PC NIC drivers.
- No AV is installed on either server or PC.
- Updated PC to windows 8.1.
- Disabled both server and PC firewalls.
- Check NLA service and all dependent services are running.
- Disabled all adapters on server except for one.
I am really hoping someone can help with this as I would really appreciate it.
Thanks.

I managed to find a solution to the problem. I noticed that the DNS server zones did not look quite right. The _msdcs zone was missing the subfolders (dc, domains, gc, pdc).
To fix this issue: on the NIC adapter I had to tick the box "register this connection's addresses in DNS" (found under TCP/IP v4 > advanced > DNS tab).
I then had to remove the DNS role, reboot then re-add the role. Problem solved. Hopefully this saves someone else pulling their hair out for an entire day.
