Hi, Sage, Sam I got a issue about the parameter 'paxos_propose_interval' with the default value 1.0. I think this parameter aim to reduce the Monitor pressure to call the propose_pending(). But, this introduces another problem, when a osd is started, it will send 3 kinds of requests to Monitor (e.g. MOSDBoot, MOSDPGTemp, MOSDAlive). Without other changes, It will take 3 seconds at least. which will increase the time that blocks the whole cluster. If the parameter 'paxos_propose_interval' is set to 0.05 or smaller, it loses the propse it designed. I think we can introduce some special process, for some kinds of messages (e.g. MOSDPGTemp, MOSDAlive), to process them immediately.
