Hi all, I am using corosync-1.1.2 on CentOS 5.3. I set token 200ms and hold 50ms in corosync.conf. Then token_retransmit_timeout is auto calculated as 47ms. Suppose very idle ring with two-node where there is no new message to send. Think about the following scenario.
1. The node A sends a token to next node will start the reetransmit timer(47ms). 2. The next node B receives a token and starts hold timer(50ms). 3. When hold timeout, node B will pass the token to node A. The 50ms is larger than 47ms, so at node A the retransmit timer will expire before receiving a token, as a result node A will resend the token until it receives it. Assuming no token lost, then there will be at least one token retransmission every token pass. Is my assessment correct? Or I am wrong? If I am correct, then should I reduce the hold timeout? Thanks hj
