Hi , I am upgrading from corosync 2.x/pacemaker 1.x to corosync 3.x/pacemaker 2.1.x
In our use case we are using a 2 node corosync/pacemaker cluster. In corosync 2.x version I was using udpu as transport method. In the corosync 3.x , as per man pages, the default transport mode is knet . And in knet it uses udp as knet method. I have the below doubts on the transport method. 1. Does knet require any special configuration on network level(like multicast enabling). 2. In corosync 2.x udp was used for multicast, in knet transport does udp mean multicast. 3. Will udpu be deprecated in future. Kindly help me with these doubts. With Regards Somanath Thilak J
