Hi, I was browsing dashboard today. Then suddently it stopped working and i got 502 errors. I checked via root login and see thet ceph health is down to WARN. I can access all rdb devices and CephFS. They work. All OSDs in server-1 is up. health: HEALTH_WARN 1 hosts fail cephadm check failed to probe daemons or devices I even restarted server-1. No luck. I'm on server-1. cephadm complains it cannot access to server-1. In basic term, server-1 cannot access server-1 (192.168.0.1) server-1: 192.168.0.1 server-2: 192.168.0.3 $ ssh -F =(ceph cephadm get-ssh-config) -i =(ceph config-key get mgr/cephadm/ssh_identity_key) root@server-1 > Success. cephadm says server-1 is not reachable. Why cephadm/ceph complain about this and what happend to my dashboard? I also redirected logs to file. I'm observing for any weird log input but unfortunately nothing helpful. Where should I look for? What am i missing? So, when I ran this command: $ ceph health detail Output was: HEALTH_WARN 1 hosts fail cephadm check; failed to probe daemons or devices [WRN] CEPHADM_HOST_CHECK_FAILED: 1 hosts fail cephadm check host server-1 failed check: Failed to connect to server-1 (server-1). Check that the host is reachable and accepts connections using the cephadm SSH key you may want to run: > ssh -F =(ceph cephadm get-ssh-config) -i =(ceph config-key get mgr/cephadm/ssh_identity_key) root@server-1 [WRN] CEPHADM_REFRESH_FAILED: failed to probe daemons or devices host server-1 scrape failed: Failed to connect to server-1 (server-1).
