I had issues with my master data storage domain and the only way was to set the hosts in maintenence mode ,delete the datacenter so i can recreate it.... I managed to delete the datacenter and the storage domains , and created a new datacenter , but now the existing clusters are not part of a datacenter and trying to add them to the datacenter gives out this error below Error while executing action: Cannot edit Cluster. Changing management network in a non-empty cluster is not allowed. and by non empty i guess it means there is a host inside that cluster ? fair enough trying to change a node cluster comes with the Host Cluster Dropdown with this Datacenter:Undefined How can i fix the catch 22 scenario without deleting clusters or hosts.. surely there should be a smarter way ?
