    Install Cluster without GUI

    Hi,

    the way to install a cluster is by installing "ha-cluster-bootstrap".
    (Even Clusterlabs points to that at http://clusterlabs.org/quickstart-suse.html)
    This installs a ton of packages, including gtk.

    I would like to install the cluster without installing a graphical environment on the server.
    The config is supposed to be deployed with ansible later anyway.
    To manage the server crmsh is enough.

    Is there any documentation what to install and configure for this?

    (The official SUSE docs are very poor. It is only how to click )

    I think I will install crmsh, pacemaker and corosync for start.

    Any advice?

    Hi MoserHans,

    > I think I will install crmsh, pacemaker and corosync for start.

    my guess is that this will get you started nicely, via the dependencies. If not automatically installed as well, add stonith and the supporting packages for pacemaker and stonith to your list.

    Pro Tip: do not run the server in any language except "c".
    (crmsh cluster init will not find your interfaces if language is German )

    I can ping the nodes from each other.
    Password less ssh is working.

    # LANG=c crm -d cluster init node1
    ends with "ERROR: cluster.init: No JSON object could be decoded"

    Code:
