Hi again,
One more update:
I connected to server-2 and ran ceph -s there. I got:
Error initializing cluster client: ObjectNotFound('RADOS object not found
(error calling conf_read_file)')
Today I created a RBD pool and created 2 RDB images in this pool. Could this be
reason for all dashboard issue and this?
Thanks,
Gencer.

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).

you may want to run:
