SIMPLE QUESTION: HOW TO MIGRATE FROM WINDOWS 2008 R2 + SQL 2012 FAILOVER CLUSTER to WINDOWS SERVER 2012 CLUSTER WITH ALWAYS ON AVAILABILITY GROUP

September 5, 2013, 10:04 am

Hello,

We have 2-node Windows 2008 R2 Enterprise Edition failover cluster with Fibre shared storage (SAN) running SQL Server 2012 SP1. Below is current configuration - very simple and classic, I would say everything by the book:

This is what I think we want to achieve:

Objectives:

1. Upgrade Windows Operating System from Windows Server 2008 R2 to Windows Server 2012

2. Migrate to SQL Server 2012 Always On Availability Group (AAG) for High Availability and Disaster Recovery

My question is how to achieve both goals?

If possible I would like to upgrade OS first. Ideally I would like to upgrade on the same hardware (because it should be minimal impact - no need to migrate data). If this is not possible, we have new hardware I can use also. But I guess it will be more impact and actual data migration will be required.

For AAG what I'm honestly missing is what would be the name of the second SQL server? Lets say my servers called DB1 and DB2, and SQL server called DB. If I create AAG, and fail-over to replica server, would SQL server name be DB as well?

I know there is lots of documentation on AAG and I went through it but I cannot find any specific information about names.

Another question I have - would 3rd server (DB3) be part of the same MSCS cluster? Or it will be separate server? How fail-over exactly works - do I use Fail-over cluster Manager to initiate failover?

Sorry for lots of questions, but any information would be appreciated very much.

Thanks!

Windows 2012 Hyper-v Cluster Live Migration Failure

January 22, 2013, 12:07 pm

This is a fairly new deployment.  When I first started having this issue, I foundhttp://support.microsoft.com/kb/2779204, which suggests that gpupdate /force will temporarily resolve the issue.  That worked for me for several weeks, but no longer.  It was always temporary and I had to do it at least once a day, but even that doesn’t work anymore and my Hyper-V guests are stuck.  I also suspect if I have a Hyper-V host failure, the guests on the failed system will not come back up on the operational host.

kb2779204 suggest adding NT Virtual Machine\Virtual Machines in the entries for Log on as a Service.  I have created a dedicated OU for the virtual hosts (as suggested by the kb article) and moved them to the new OU. I then addedNT Virtual Machine\Virtual Machines in the entries for Log on as a Service, then gpupdate /force and then wait minutes, then hours. It still doesn’t work.  I get 2 slightly different depending on which server I initiate the live migration.

If from the server that currently is running the guest (HV1):

Live migration of 'Virtual Machine vg1' failed.

Virtual machine migration operation for 'dc4' failed at migration source 'HV1'. (Virtual machine ID 140C8893-44EC-481B-B8D5-52FCB8D422DC)

The Virtual Machine Management Service failed to establish a connection for a Virtual Machine migration with host 'HV2': General access denied error (0x80070005).

The Virtual Machine Management Service failed to establish a connection for a Virtual Machine migration because the destination host rejected the request: General access denied error (0x80070005).

If from the server attempting to move the guest to (HV2):

Live migration of 'Virtual Machine vg1' failed.

Virtual machine migration operation for 'vg1' failed at migration destination 'HV1'. (Virtual machine ID 140C8893-44EC-481B-B8D5-52FCB8D422DC)

Having 2 file share witness for a 2 node windows cluster

September 13, 2013, 1:32 pm

Hello,

I have a two node windows 2012 cluster on which I have configured SQL Server 2012 High Availability Groups.

These two SQL server nodes are in different data centers.

These are used by ASP.NET application which is also running in 2 node NLB Cluster with each node being in a data center.

The following diagram depicts my setup


Now I when configuring the cluster, I am configuring it with "Node and File Share Majority"

I do not use any SAN at all. no Shared Storage.

I don't have any other data center. So no 3rd data center. Only 2 data centers.

Currently I have created a fileshare on web server 1 and configured the cluster. The problem is that if I loose the data center 1. then my cluster will go down. desptite the fact that my Web Server 2 and SQL Server (Mirror) are alive.

My intention is that even when an entire data center is down. my application contiues to work because I have all the components of my application (web server and database server) in the second data center.

Currently the file share is a single point of failure and since I don't have shared storage across data centers if the machine on which the file share resides goes down, then the cluster goes down... even though it has healthy machines in other data centers.

How do I resolve this? Can I provide 2 file shares? one on web server 1 and second on web server 2 as witness?

val it: unit=()

Win2012 R2 - Shared SAS - cluster validation failes: two disk cannot be distinguished from one another

November 7, 2013, 6:29 am

Hi

I am trying to validating a new cluster (SOFS) for Windows 2012 R2. There are 2 server nodes and 2 JBOD (SAS).
The server nodes have 2 LSI SAS controllers and the JBOD have dual controller. 
All hardware is listed on the Windows Server Catalog.

When I run the cluster validation with both LSI controller enabled. It reports an error:
Two disks have been found on node SOFS1-N2.itaas.local that cannot be distinguished from one another.

The cluster validation sees each SAS harddisk twice! When running get-physicaldisk powershell command the disk are listed only once!

Followed the pre-request for installing SOFS, MPIO is installed.

When I disable one LSI SAS controller in each server node. The cluster validation works fine. Each harddisk is detected once.

Any ideas?

Windows 2012 File Server cluster - issue with adding file share

October 14, 2013, 7:15 pm

Greetings All,

I have physical 2-node (nodes A and B) Windows 2012 Standard cluster with File Server role installed (standard SMB, no CSV/CAFS). Both nodes are alike, hardware and software-wise with the same patching level. LUNs presented for clustering are served by iscsi (EMC VNX).

The issue that I'm running into is when I try to create new shares. While running 'Add File Share -> Quick' wizard from Failover Cluster Manager on node B with file server being active on node A, I don't see my (online) volume available for selection in the 'Share location'->'Select by volume'. It is grayed out. The same when I try to run the wizard locally on the active node. Only when I run the wizard from node A with File Server being active on node B I'm able to see the volume in the wizard. Running the wizard locally on active node yields the same problem.

I'm using Domain Admin account for all above.

As a separate note, I get the following warning message on the first screen when running add file share wizard:

"Unable to retrieve all data needed to run the wizard. Error details: Cannot retrieve information from server (A or B, depending on which node I run it from). Error occurred during enumeration of SMB shares. The WinRM client sent a request to HTTP server and got a response saying the requested HTTP URL was not available. This is usually returned by a HTTP server that does not support WS-Management protocol"

Obviously I don't have additional roles/features installed to provide support for HTTP based requests but I don't think this is mandatory. Besides, I get the same error even in the only scenario mentioned above that allows me to create shares. 

Also, when trying to create new shares from 'Server Manager-> File and Storage Services ->Shares' hangs indefinitely with "loading data...'

Any help with getting new share creation/making volume appear when running the wizard across both nodes consistently working would be greatly appreciated and rewarded.

Thanks,

Peter

Analysis Services doesn't fail over - event ids 1069, 1042

Cluster Resource 'Analysis Services' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
Generic Service 'Analysis Services' failed with error '0'. Please examine the application event log.

I have set up a 2 node active-passive cluster on Windows 2008 R2 enterprise & SQL Server 2008 R2 (SP2) 10.50.4000.0 (X64).

Everything is working as far as failover and failback, except when node1 (preferred) goes down, and node 2 comes online, everything works except SSAS.

I get the two errors listed at the top of this post. I have looked everywhere on Google and checked the Microsoft KB's.  Nothing seems to reference the problem I'm having or a solution to it. The application event logs and SQL logs don't give any other clues.  There are no other errors. 

What can this possibly be?  Where can I look? are there any more detailed logs?  Any information would be greatly appreciated.

CSV redirect access

Hi,

I have a simple configuration, two windows 2008 R2 cluster with iSCSI shared backend. The CSV is online when I created, however, after I migrate the CSV to the other node, the status is rediect access. There is a error in eventlog complains it can not find the physical disk (event id 1034). The node is the owner before migrate and the disk is right there and I can read the signature. So what is the problem?

BTW, I passed the validation test without errors.

Thanks,

how to delete a failed file share witness

May 25, 2011, 9:57 am
$

I have a 2 node 2008SP2 (Geographically separated) cluster. I use file and node majority for quorum. There is a file share at third site and both nodes can ping/open the share and the nodes have full controll of the share. Also, there are other cluster/nodes using the same share for quorum. This has worked for several years. After the last round of MS patches the file share witness resource would not come back online for 1 cluster. I tried forcing it online several times but I cancelled after 10 minutes or so. I found that I can add another folder in the original location and reran the qurom wizard, and it came online. I am guessing that maybe the multiple clusters using the same single folder is not good, not sure why it worked for so long though. Anyway, the delete function is gone from the failed file share witness, how can I get rid of the old failed resource? 

 

Thanks

Hello Guys,

I have created a cluster to configure Hyper-V for 2 Nods, everything was greate and works perfectly, next day the storage hang and the cluster didn't work any more, I have destroyed the cluster the removed the cluster feature from both nods, deleted the cluster-computer from AD and the deleted the storage. after we fixed the storage, I have reconnect the storage, installed the cluster service on both nods, then I have validate the configuration and I had everything green 100%.

while creating the cluster, I faced an issue Unable "to successfully cleanup" I kept trying and removed the anti-virus, restarted the servers manytime, then I ended up to have another error, direclty when I add the server name on the creat cluster wizard, its telling me that the computer I'm adding is joined to cluster.

I think I need to do some cleaning to the previous cluster, can I have some help here ?

Regards..

Disk Space in Windows Drive

Hello

We have two Windows 2008 R2 Enterprise Servers, configured as nodes for a failover cluster, hosting virtual machines. Both are connected to a SAS disks Storage system.

Although it work fine there is something I am a bit worried. Windows disk space is 130 GB in both servers, and in both of them there are only 30 GB free, I have been looking for the files or folders that take so much space, but I couldn't find it.

Is this normal? Does it has to do with the cluster configuration. I looked even in hidden files or folders but I didn't find the reason.

I could not understand how such a Windows installation take as much space.

Thank you very much.

Kind Regards.

File Share Witness is not a valid File share path

November 25, 2013, 2:34 pm
$

I have two Windows 2008 R2 VMs (ESXi) running Double-Take.

We currently have a Health-check running on our Netscaler to force a failover from the primary VM to the secondary VM if the Netscaler cannot access the an SMB share on the Primary VM.

This hasn't proven to be a good method of providing Fault Tolerance, so I am trying to cluster these two VMs using a File Share Witness.

(I should add that my client engineers this solution, I only implement according to their requirements).

The Witness share has been created on an EMC VNX. My domain account and the domain Cluster Computer Name account both have Full Control permissions on the Share.

I have installed the File Services Role as well as the Failover Clustering Feature on both VMs.

To configure the Quorum, I am selecting Node and File Share Majority (For Clusters with special configuration).

I am providing the IP address and share name in the form of \\<ipaddress>\<sharename>.

The wizard returns \\<ipaddress>\<sharename> is not a valid share path.

Reading the documentation from Microsoft, there is a statement saying that the witness share should have nothing else stored or using that share.  Within the shared folder is an .etc folder with Everyone, Unix UID=0x0, and Unix GID=0x0.  All three accounts have 'special' permissions, Traverse, List, Read. I am unable to delete this folder (haven't tried to take ownership) because I don't know what the impact could be. 

Is it possible that this folder is preventing the share from becoming a Witness Share?

Any other thoughts, ideas?

The client did test this in their lab, but used a file share on another Windows server rather than a NAS.

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

Hi

I want to create multiple NLB clusters on a single network adapter on windows 2012 server to support load balancing for multiple different web sites , each with different DNS Name.(Two Hosts)

In the NLB Manager I create first Cluster  and determine my hosts (multicast mode).

Then I add another ip address to Nic of my hosts , when I want to create second cluster and determine my host , there is no interface .and i get error "The RPC server is unreachabale on the specified server". while I can ping both of ip address of my hosts. also the firewall is off.

How Can I configure multiple NLB clusters on a single network adapter?

Thank you for your help!
