Hi guys. I have a problem when reading the codes of the ceph. In the osd.cc, the tick method will check if the mon is timeout by compare "now - g_conf->osd_mon_ack_timeout" with last_pg_stats_ack, if it's timeout, then monc->reopen_session() will be called to try to re-connect to the mon. The question is that, if the network has splited so that the osd will never be able to connect to any mon, how do the PGs on the osd know that? I think the PGs may still believe they are heathly with the current OSDMap even the mons have already mark their osd down & out (but couldn't tell them for the network problem), Then they continue to sevice clients who have the same OSDMap with them. So two primary PG may exist in the cluster at the same time which is terrible. I want to knwon any code work with this issue or is there some wrong with my opinion?
