Instance not selectable when trying to remove node from a cluster

  • Hi All, I have installed SQL on one of the nodes of a 2 node cluster but it failed, this was due to the service account not being a local admin, thought it was a member of the AD group that was a local admin. Anyway, I granted permission to that group, but still couldn't add the second node, because of the error after I installed. I can get the instance it is running, but there is no SQL agent present. I Tried a repair but that didn't work, so I decided to remove the node through the setup, but the instance does not appear, there is nothing in the dropdown list. Never seen that before. I have located this article

    http://msdn.microsoft.com/en-us/library/ms180973(SQL.90).aspx

    Not sure about this, but it is an option.

    This is probably not applipacable to a cluster.

    Any advice appreciated

    Any advise would be appreciated.

  • which version of SQL Server are you attempting to cluster?

  • It's all 2008R2 OS and SQL

  • when you get the error

    are you creating a failover cluster instance or adding a node to a failover cluster instance

  • I got it sorted, I decided to proceed with my cluster build and it seems that installing another instance resolved the issue, I got it uninstalled successfully. My recommendation. DON'T install SQL 08 on WIN 08 in a 2000 domain, wasn't my choice. The customer is always right.

  • We have two SQL servers configured as a failover cluster. One of them is a physical and the other is a VM.

    Occasionally we are having problems with this, as the node tries to failover eventhough the cluster operations are disabled.

    Our goal is virtualize the physical SQL server and remove the failover cluster functionality.

    The problem is while trying to uninstall the cluster, the instance does not appear in the drop down.

    How can we uninstall the cluster and proceed with virtualizing the physical server?

    Thanks,

    Perfectly reasonable I don't see any issue here.

    What exactly do you mean here, please explain what you have done\disabled?

    What do you intend to do with the databases, etc that currently reside on the clustered instance?

  • We just want to move all the databases to one virtualized machine and not have any more clusters.

    So currently the failover is disabled and we are trying to unistall the cluster. However the drop down does not show anything.

    Is there any set of recommended steps before virtualizing this kind of a setup?

    Thanks.

    How have you disabled failover?

    You're running the remove node option from the sql server 2008 installer?

    -----------------------------------------------------------------------------------------------------------

  • Sorry for the mistake, unfortunately there was another installation of SQL2008 on the same server, so we were trying the wrong instance.

    The instance is visible now after choosing the correct installation.

    Once the cluster is removed, we need to virtualize the physical SQL server.

    Are there any other recommended steps to follow

    after this and continue to virtualize this node?

    Thanks

  • Rather than virtualise the existing server, just deploy and configure a new VM, retrieve your existing backups from the old server. You'll also need to script out any objects such as jobs, logins, etc.
