    Hi,

    MySQL NDB Cluster requires at lest two data nodes for high availability. For this reason ClusterControl does not support importing a single data node.

    Thanks,
    Krzysztof

    root@clustercontrol-mysql:/opt# s9s cluster --register --cluster-type=ndbcluster --nodes='ndb_mgmd://10.142.0.21;ndbd://10.142.0.22,mysql://10.142.0.23' --vendor=oracle --cluster-name='ndbcluster' --wait

    The 'cluster --register' is not a valid mode.

     

    Is this a valid command ?  Please suggest, if there is a command line way of forced import of ONE node SQL cluster & later install multiple nodes with the help of cluster control

    Hi Anand,

     

    It looks right to me:

    [root@testccnode html]# s9s cluster --register --cluster-type=ndbcluster --nodes='ndb_mgmd://10.142.0.21;ndbd://10.142.0.22,mysql://10.142.0.23' --vendor=oracle --cluster-name='ndbcluster' --wait

    Register NDB Cluster

    Hello,  I have the latest version....as per this tool update.

     

     

    testgtotest@clustercontrol-mysql:~$ sudo apt-get install s9s-tools

    Reading package lists... Done

    Building dependency tree

    s9s-tools is already the newest version (1.7.20181108-release1).

    The following package was automatically installed and is no longer required:

      grub-pc-bin

    Use 'sudo apt autoremove' to remove it.

    After updating the VM user (instead of root user), I am able to proceed.    The next issue I see here is:

     

    testgtotest@clustercontrol-mysql:~/.ssh$ s9s cluster --register --cluster-type=ndbcluster --nodes='ndb_mgmd://10.142.0.21;ndbd://10.142.0.22,mysql://10.142.0.23' --vendor=oracle --cluster-name='ndbcluster' --wait 

    No user name set.
