[ceph-users] shutdown primary monitor, status of the osds on it will not change, and command like 'rbd create xxx' would block

Hi sage, I'm testing ceph feature,and now have a probem make me confused. Network construction is as shown in the figure below: serverB is primary monitor , it has 5 osds serverC is secondary monitor, it has 5 osds serverD is tertiary monitor,it has 5 osds client A use a rbd block via 'rbd

[ceph-users] when one osd is out of cluster network, how does the mon can make sure this osd is down?

hi， 3osd（B\C\D）in cluster network，3 replication, monitor (A) [cid:image003.png@01D0E27F.A7634850] if osdB is out of cluster network(still can communicate with mon(A))，then osdC and osdD will report to A that B is down,then MON(A) will mark B down,at this time,does the ceph-osd process on B

Hi, I'm testing reliability of ceph recently, and I have met the flapping problem. I have 2 replications, and cut off the cluster network ,now flapping can not stop,I have wait more than 30min, but status of osds are still not stable; I want to know about when monitor recv reports from osds
