Hi all, after upgrading from 12.2.7 to 12.2.8 the standby mgr instances in my cluster stopped sending beacons. The service starts and everything seems to work just fine, but after a period of time the mgr disappears. All of my three mgr daemons are running. [root@ceph01 ~]# ceph mgr dump { "epoch": 69, "active_gid": 1734502, "active_name": "ceph01", "active_addr": "192.0.2.1:6832/35134", "available": true, "standbys": [ { "gid": 1734790, "name": "ceph02", "available_modules": [ "balancer", "dashboard", "influx", "localpool", "prometheus", "restful", "selftest", "status", "zabbix" ] } ], } Some time later I get this: [root@ceph01 ~]# ceph mgr dump { "epoch": 69, "active_gid": 1734502, "active_name": "ceph01", "active_addr": "192.0.2.1:6832/35134", "available": true, "standbys": [], ... } Here is the log. Before the upgrade the mgr posts a standby beacon every 2 seconds. After the upgrade the message is shown only on startup. 2018-09-13 10:10:19.191188 7f674b736700 1 mgr send_beacon standby 2018-09-13 10:10:21.191565 7f674b736700 1 mgr send_beacon standby 2018-09-13 10:10:23.191952 7f674b736700 1 mgr send_beacon standby 2018-09-13 10:10:25.192320 7f674b736700 1 mgr send_beacon standby 2018-09-13 10:10:27.192695 7f674b736700 1 mgr send_beacon standby 2018-09-13 10:10:29.193071 7f674b736700 1 mgr send_beacon standby 2018-09-13 10:10:29.434679 7f674af35700 -1 received signal: Terminated from PID: 1 task name: /usr/lib/systemd/systemd --system --deserialize 22 UID: 0 2018-09-13 10:10:29.434692 7f674af35700 -1 mgr handle_signal *** Got signal Terminated *** 2018-09-13 10:13:12.390340 7f7c56fcb7c0 0 set uid:gid to 167:167 (ceph:ceph) 2018-09-13 10:13:12.390377 7f7c56fcb7c0 0 ceph version 12.2.8 (ae699615bac534ea496ee965ac6192cb7e0e07c0) luminous (stable), process ceph-mgr, pid 2368 2018-09-13 10:13:12.396043 7f7c56fcb7c0 0 pidfile_write: ignore empty --pid-file 2018-09-13 10:13:12.448859 7f7c56fcb7c0 1 mgr send_beacon standby 2018-09-13 10:13:12.466768 7f7c4e11e700 1 mgr init Loading python module 'balancer' 2018-09-13 10:13:12.506115 7f7c4e11e700 1 mgr init Loading python module 'dashboard' 2018-09-13 10:13:12.701486 7f7c4e11e700 1 mgr init Loading python module 'prometheus' 2018-09-13 10:13:12.772187 7f7c4e11e700 1 mgr init Loading python module 'restful' 2018-09-13 10:13:13.282123 7f7c4e11e700 1 mgr init Loading python module 'status' 2018-09-13 10:13:13.390284 7f7c4e11e700 1 mgr load Constructed class from module: dashboard Let me know I have to provide more information on this.
