Hello, Frank, Frank Schilder wrote: : Might be a problem I had as well. Try setting : : mon_sync_max_payload_size 4096 : : If you search this list for that you will find the background. Thanks. I did ceph tell mon.* config set mon_sync_max_payload_size 4096 ceph config set mon mon_sync_max_payload_size 4096 and added "mon_sync_max_payload_size = 4096" into the [global] section of the mon host to be (re-)added, and ran systemctl restart ceph-mon@mon1.service on that host. But it did not help - mon1 did not join the cluster. I also added "debug_mon = 20" to the ceph.conf of mon1 host. Now the log is more verbose, and the last page of the log file says the following: 2022-09-08T22:30:05.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 timecheck_finish 2022-09-08T22:30:05.409+0200 7f68c6ef9700 15 mon.mon1@-1(probing) e0 health_tick_stop 2022-09-08T22:30:05.409+0200 7f68c6ef9700 15 mon.mon1@-1(probing) e0 health_interval_stop 2022-09-08T22:30:05.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 scrub_event_cancel 2022-09-08T22:30:05.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 scrub_reset 2022-09-08T22:30:05.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 cancel_probe_timeout (none scheduled) 2022-09-08T22:30:05.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 reset_probe_timeout 0x560bd3bd9f40 after 2 seconds 2022-09-08T22:30:05.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 probing other monitors 2022-09-08T22:30:06.352+0200 7f68c8efd700 10 mon.mon1@-1(probing) e0 handle_auth_request con 0x560bd4951800 (start) method 2 payload 22 2022-09-08T22:30:06.352+0200 7f68c8efd700 10 mon.mon1@-1(probing) e0 handle_auth_request haven't formed initial quorum, EBUSY 2022-09-08T22:30:06.352+0200 7f68c46f4700 10 mon.mon1@-1(probing) e0 ms_handle_reset 0x560bd4951800 - 2022-09-08T22:30:07.409+0200 7f68c6ef9700 4 mon.mon1@-1(probing) e0 probe_timeout 0x560bd3bd9f40 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 bootstrap 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 sync_reset_requester 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 unregister_cluster_logger - not registered 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 cancel_probe_timeout (none scheduled) 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 reverting to legacy ranks for seed monmap (epoch 0) 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 monmap e0: 2 mons at {mon2=[v2:X.Y.1.2:3300/0,v1:X.Y.1.2:6789/0],mon3=[v2:X.Y.1.3:3300/0,v1:X.Y.1.3:6789/0]} 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 _reset 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing).auth v0 _set_mon_num_rank num 0 rank 0 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 cancel_probe_timeout (none scheduled) 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 timecheck_finish 2022-09-08T22:30:07.409+0200 7f68c6ef9700 15 mon.mon1@-1(probing) e0 health_tick_stop 2022-09-08T22:30:07.409+0200 7f68c6ef9700 15 mon.mon1@-1(probing) e0 health_interval_stop 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 scrub_event_cancel 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 scrub_reset 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 cancel_probe_timeout (none scheduled) 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 reset_probe_timeout 0x560bd3b3a3a0 after 2 seconds 2022-09-08T22:30:07.409+0200 7f68c6ef9700 10 mon.mon1@-1(probing) e0 probing other monitors 2022-09-08T22:30:08.400+0200 7f68c6ef9700 11 mon.mon1@-1(probing) e0 tick 2022-09-08T22:30:08.400+0200 7f68c6ef9700 20 mon.mon1@-1(probing) e0 sync_trim_providers 2022-09-08T22:30:08.822+0200 7f68c36f2700 10 mon.mon1@-1(probing) e0 get_authorizer for mon 2022-09-08T22:30:08.873+0200 7f68c8efd700 10 mon.mon1@-1(probing) e0 handle_auth_request con 0x560bd49be800 (start) method 2 payload 22 2022-09-08T22:30:08.873+0200 7f68c8efd700 10 mon.mon1@-1(probing) e0 handle_auth_request haven't formed initial quorum, EBUSY 2022-09-08T22:30:08.873+0200 7f68c46f4700 10 mon.mon1@-1(probing) e0 ms_handle_reset 0x560bd49be800 - 2022-09-08T22:30:08.894+0200 7f68c86fc700 10 mon.mon1@-1(probing) e0 get_authorizer for mon -Yenya -- | Jan "Yenya" Kasprzak <kas at {fi.muni.cz - work | yenya.net - private}> | | http://www.fi.muni.cz/~kas/ GPG: 4096R/A45477D5 | We all agree on the necessity of compromise.
