Created attachment 526639 [details] Proposed patch Description of problem: In a 10-node cluster where all nodes are booting up and starting corosync at the same time, sometimes during this process corosync detects a node as leaving and rejoining the cluster. Occasionally the downlist that gets picked contains the local node. When the local node sends leave events for the downlist (including itself), it sets its cpd state to CPD_STATE_UNJOINED and clears the cpd->group_name. This means it no longer sends CPG events to the CPG client. Version-Release number of selected component (if applicable): 1.4.1
