New API tested using the provided upstream unit test program: > [root@virt-248 ~]# rpm -q corosync > corosync-3.1.0-1.el8.x86_64 > [root@virt-248 ~]# cd bz1887400-testapp > [root@virt-248 bz1887400-testapp]# ./testquorummodel > quorate 1 > Waiting for quorum events, press ^C to finish > ------------------- > nodelist notification called > ring id = 1.2c > num members = 5 1 2 3 4 5 > num joined members = 0 > num left members = 0 > quorum notification called > quorate = 1 > ring id = 1.2c > num nodes = 5 1 2 3 4 5 Stop cluster on another node: > nodelist notification called > ring id = 1.30 > num members = 4 1 3 4 5 > num joined members = 0 > num left members = 1 2 > quorum notification called > quorate = 1 > ring id = 1.30 > num nodes = 4 1 3 4 5 Start the cluster on the node again: > nodelist notification called > ring id = 1.35 > num members = 5 1 2 3 4 5 > num joined members = 1 2 > num left members = 0 > quorum notification called > quorate = 1 > ring id = 1.35 > num nodes = 5 1 2 3 4 5 The list of current/joined/left nodes is passed via the new nodelist notification callback API.
