I am new to SQL Server 2012 clustering.I added a new instance to one of the two nodes.when I try to move it to the other node it fails.Do I need to install it on both?If so, what options do you install on the second node?
View 7 RepliesI've a fresh installation of SQL Server 2014 Enterprise on Windows Server 2012R2. I've setup de Windows Server Failover Cluster and the validation test has been successfully passed. I use mountpoint so I've disk M: that is the host drive for mounted volume m:Isql2014A that is the base folder for mounted volume
On that folder I've 5 mountpoint:
1) m:isql2014a empdbdata
2) m:isql2014a empdblog
3) m:isql2014auserdata
4) m:isql2014auserlog
5) m:isql2014auserlog
into these 5 mountpoint I've placed the SQL Server files.
After the installation of the first FCI I've re-run the cluster validation wizard and again it has passed successfully. When I try to failover the instance from one node to the other I have 2 problem:
1) every time I do failover, some disks fail to come online for a while and then succeed :
Cluster resource 'CLD - IstA - TempDB Data' of type 'Physical Disk' in clustered role 'SQL Server (ISQL2014A)' failed. The error code was '0xaa' ('The requested resource is in use.').
2) sometimes the SQL Server service fails to start, in the error log I see that the master database is not accessible. The master database in into the m:isql2014abinbackup.
In QA we have a two-node cluster with four instances of sql. In trying to add a fifth, I was given an IP address already in use so the install hung.
I removed it from the cluster but it is still there in the registry etc on the node I was working on.
I read about using the maintenance tab of the sql server install to "remove a node" but the terminology is confusing. To me a node is a physical server and an instance is an instance of sql server -- not the same at all but they are often referred to as the same thing.
I definitely don't want to remove one of the servers from the cluster.
I´ve been reading that SQL Server 2012 Always On is dependent on having a Windows Failover Cluster setup. Is that correct ?

I ran the Advanced cluster preparation for a new sql instance on an existing cluster.
Slq Server 2012.
After is completed, it was successful, I realized I specified the wrong Instance Root directory.
Is it possible to remove what the preparation installed? Or is it possible to change the root directory?

View 9 Replies View RelatedI'm reading up on Always on and I am confused what is the difference between AlwaysOn Availability Groups and AlwaysOn Failover Cluster Instances.
View 3 Replies View RelatedI had a cluster running on 3 nodes (windows failover cluster) with server 2012 and SQL server 2012 running in the cluster. Well, I thought I'd just go ahead and rename all 3 of the hosts with new hostnames and it apparently broke the cluster pretty bad. Now when I open failover cluster manager I cannot see anything nor can I connect to the cluster object in AD. I re-named all of the hosts back to their original names but that didn't work.
View 5 Replies View RelatedWe are implementing a multi-site (Windows Server Failover Cluster) WSFC to enable Always On between our primary and DR site. We are not going to use SQL clustered instances. We are not planning to use shared disks. Each node is running a standalone instance of SQL 2012.
I have successfully configured a 3 node multi-site Windows failover cluster with no shared storage. For quorum, I have defined a File Share Witness (FSW). The FSW has voting rights and is in the DR site. The setup looks like this –
WSFC –
•Node A – Site #1 (voting right = 1)
•Node B – Site #1 (voting right = 1)
•Node C – Site #2 (voting right = 0)
•FSW – Site #2 (voting right = 1)
Again - There are no shared disks in our setup. We are not going to use SQL clustered instance. We are going to use Always On with these 3 nodes.
SQL Always On –
•Node A – Site #1 (Primary Replica)
•Node B – Site #1 (Readable Secondary)
•Node C – Site #2 (Readable Secondary)
All the setup including the “availability group” works properly under this setup. However, a failover to site #2 under DR situation is not working and I know why but don’t know what needs to be done to fix the problem.
The following works fine –
•Automatic failover between nodes A and B (same site – site #1)
•Forced failover to node C in site #2 provided at least one of the nodes in site #1 is up (non – DR situation) - this will ensure the cluster is up
The following is not working –
•Forced failover to node C in site #3 when both nodes in site #1 are lost (true DR situation) – This is because the cluster is not up at this point.
I know I have to bring the cluster up somehow and I have not been able to do so by restarting the cluster service.
I tried to run the command to start cluster service.
Question –
How can I FORCE the cluster to come up in Site #2 on node C when it has no voting rights?
I have always worked with even number of nodes and shared disks with traditional clustering. I am not sure what needs to be done in this scenario with 3 nodes and a FSW.
How can we find the cluster failover count in always on ?
As my AG is configured as synchronous mode , AG went offline and we manually restarted the AG service when we check the properties on AG role they r in default setting ?
Approach 1:
Prod - shared storage between server 1 and 2
Server1: clustered SQL instance with availability group as primary
Server2: Passive server for clustered instance of PROD
DR - shared storage between server 1 and 2
Server1: Clustered SQL instance with availability group as replica
Server2: Passive server for clustered instance of DR
Approach 2: Using replicated SAN
Prod -
Server 1: Standalone instance with availability group as Primary
Server 2:Standalone instance with availability group as replica
DR -
Server 1: Offline until Disk group 1 (Prod server 1) has been broken and brought online at DR
Server 2: Offline until Disk group 2 (Prod server 2) has been broken and brought online at DR
Both these approaches will work wont they? I have only built and played with normal availability groups across servers, not mixing it with clustered instance replicated SAN
I am trying to install SQL Server 2012 onto an already configured and validated windows failover cluster (server 2012) but the process is hanging after installing the setup files.
The last entry in the log is:
running discovery on remote machine
and I've left it hanging like this for 4 hours and nothing happens.
would like to know if it's possible to install SQL Server Failover cluster instance with shared storage along with standalone installation with Always on ( always on uses WSFC underneath).

We have an active/active two-node QA cluster with four instances of sql. I need to add a fifth. In the past I always moved existing instances to the other node while installing a new instance.
Other than impacts to users from install reboots, is that a hard requirement?
QA is reluctant to have me put the four existing instances on one node for most of a day, fearing big performance slowdowns. Each node has 250GB of memory and each instance is allowed 50GB. Netapp disk backend.
I am trying to install the MS SQL Server 2012 Failover Cluster on Windows Server 2012 . I successfully Installed the Failover cluster instance on my primary node.
But when I am running the installation process on passive node to add node in the failover cluster I am stuck with very unique kind of issue.
I am following the Standard process of Installation and I am getting the same windows for each next process, but after License Agreement window when I get the Cluster Node Configuration window, then in "SQL Server Instance Name" drop down box I am not getting the Name of Instance which is already installed on the primary node. But this Instance complete information is appearing in below given box.
Only issue is Instance name is not appearing in the drop down list, that's why I am not able to select and when I click on next it trough error and do not proceed.
We have 2 nodes window Server 2012 R2 and SQL Server 2012 Enterprise Version cluster setup. We can switch roles and Node to one node to another and revert back to previous node with out any issues. But we are facing when one Node is restarted. We could not restart that Node in cluster Service start in Failover cluster Manager. Error Details is displayed as below inside double code."Cluster node NODE1 could not to join the cluster because it failed to communicate over the network with any other node in the cluster. Verify the network connectivity and configuration of any network firewalls."
I checked windows firewall. windows firewall is all of in Node1, Node2, SAN and DC.I have disabled and enabled the Internal and private network of Node 1. I have validated the cluster. it is showing no error though.
Node1:

Private Network: Not configured.pinging to each other ip is successful from one node to another.
We have sql server 2005 installed locally on 2 servers and want to set up failover clustering. Do we need to uninstall what we have then install as failover cluster? Thanks.
I have a production failover cluster running SQL Server 2000 at SP3that I want to upgrade to SP4. I do not have a test failover clusterto test with so I need the install on the primary server to work thefirst time. Per the information I have I just install the patch on theprimary server and it will install both on the primary and on thesecondary.However, I remember when I did the initial install and it failed. Thefirst problem traced to the fact that the install uses temporary filesunder the profile of the installing administrator and the id had neverlogged into the second server so the install failed on creating thetemporary file. The was a second problem that related to an OS featurethat had to be off for the install to work.If anyone out there has done this upgrade and remembers encountering aproblem and its fix/workaround I would appreciate a head up warning.Thank you-- Mark D Powell --

Hi,
We have configured two SQL Server 2005 in a cluster (without Witness).
We have severals ASP (using ADO) that are connecting to SQL Server 2005 with SQL Native Client in a DSNLess connection String :
driver={SQL Native Client}; server=MAINMAIN; Failover Partner=BCKUPBCKUP; uid=log;pwd=pwd;database=MyBase
When using this connection string, the connection to MAIN is alrigth, but when we simulate a unavailability situation on "MyBase" or on the entire MAIN instance, the new connection are joining the MAIN and not the BCKUP SQL Server.
We tryed several Connection Strings including Failover_Partner, Initliag Catalog instead of database... but no one succed in joining the BCKUP SQL Server.
I precise that the DNS on the PC that connect to SQL server is configured and both MAIN and BCKUP are resolved in command line or in explorer.
Is there an other driver that must be used, or is there an other parameter to set in the connection string ?
Regards.

Hello All, I am trying the following script to upgrade SQL Server 2005 SP1 to SP2. I have an Active Passive cluster configuration. I have default instances of SQL Server. I am using the following script.
start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /allinstances /quiet.
The sql server install fails to run. When I used the above command with just
start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /quiet still the summary.txt file came with authentication success and that is all. I changed the above script and did
start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /instancename=instancename of the cluster
This worked, however the install patched the passive node (DB engine, all the cluster unaware components) but failed to patch the DB engine on the Active node. I had to run the SQL Server sp2 install manually but still it did not patch the DB engine on the primary node
1. Can someone please help me with this issue as I want the unattended install to work. so it installs both active and passive node. I will post the final output and also the ADS script to do this as a bonus if this works.
Here is the summary.txt file.

IF you need to change the IP Address of a SQL Server Failover Cluster instance, here is the steps:
1. Open up Failover Cluster manager.
2. Expand the MS Cluster Instance that your SQL Cluster instance resides on.
3. Expand Services and applications.
4. Select the SQL Server Service.
5. In the main window pane (Middle Screen), you should see your SQL Server Cluster name, expand the plus to the left of it.
6. Under your SQL Server Cluster name, you should now see an 'IP address' section, right click on it and go to properties.
7. In the properties pane, you can change your IP address by entering a static IP.....or assigning a DHCP enabled IP.
if it is supported to install Reporting Services on both the active and passive nodes in an SQL Server Failover Cluster and use the non-active node as a warm standby?We have relatively simple reporting requirements so the idea would be that if Node 1 went down, we could just repoint our users are Node 2 temporarily. Both reporting services instances would be configured to target the same SSRS database running on the SQL Cluster.
