    28 Node HA Cluster (can't join nodes into cluster)

    It seems like it did the trick. So all it took was for me to register here for help and have a second look at my own stats - which i already double checked. Thanks for your help though, really appreciated. #dontbestressedwhilesettinguplotsofstuff
