Hello everybody, I'm encountering strange behavior on an infrastructure (it's pre-production but it's very ugly). After a "drain" on monitor (and a manager). MGRs all crash on startup: Mar 07 17:06:47 pprod-mon1 ceph-mgr[564045]: mgr ms_dispatch2 standby mgrmap(e 1310) v1 Mar 07 17:06:47 pprod-mon1 ceph-mgr[564045]: mgr handle_mgr_map received map epoch 1310 Mar 07 17:06:47 pprod-mon1 ceph-mgr[564045]: mgr handle_mgr_map active in map: 1 active is 99148504 Mar 07 17:06:47 pprod-mon1 ceph-mgr[564045]: mgr handle_mgr_map Activating!

I have the impression that the MGRs are ejected by the monitors, however after debugging monitor, I don't see anything abnormal on the monitor side (if I haven't missed something). All we can see is that we get an exception on the "_add_conn" method ( https://github.com/ceph/ceph/blob/v17.2.6/src/mon/MonClient.cc #L775) Version : 17.2.6-170.el9cp (RHCS6) _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
