Hi Angus: I found that corosync sends downlist(alias leftlist in CPG) and joinlist separately to CPG client after a new ring established. When a node lefts from or joins into a ring, only downlist or joinlist contain content, this behavior seems not strange. But suppose there are two ring: Ring(A,B), Ring(C,D,E,F) that are forming into a new ring, and these nodes: B,E,F dropped in the GATHER state, then only these nodes: A,C,D will form the new Ring(A,C,D). And corosync will send downlist(B) and joinlist(C,D) as two confchg events to the CPG client of node A. This will make CPG client confused. The correct way is that send _Only_ one confchg event containing both downlist and joinlist to the CPG client. In this case, 1) The CPG client of A should receive only one confchg as following: memb:A,C,D left:B join:C,D 2) The CPG client of C,D should receive only one confchg as following: memb:A,C,D left:E,F join:A Angus, what is your opinion? If you agree with me, I would summit patch to fix it. -- Yunkai Zhang Work at Taobao _______________________________________________ discuss mailing list discuss@xxxxxxxxxxxx http://lists.corosync.org/mailman/listinfo/discuss
