Hello, I'm planning migration of current two clusters based on CentOS 6.x with Cman/Rgmanager going to CentOS 7.x and Corosync/Pacemaker.
As the clusters and their services are on the same subnet, and there no particular security concerns differentiating them, I'm also evaluating the option to transform the two clusters into a unique 4-node one during the upgrade. Currently I'm testing a virtual 4-node CentOS 7.4 cluster inside oVirt 4.2 and things seem to behave well. Before going further in deep with tests and so on, I'd like to check with the community about how many CentOS 7.x clusters composed by more than two nodes are in place and what are the feedbacks on them in terms of incremented latency/communication, ecc scaling out. Also general feedback related to CentOS 6 and scalability of cluster nodes number is welcome. Thanks in advance, Gianluca _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
