Can you please paste the output of the following command? ceph orch host ls Zitat von "Roberto Maggi @ Debian" <debian108@gmail.com>:
Hi you all,
it is a couple of days I'm facing this problem.
Although I already destroyed the cluster a couple of times I continuously get these error
I instruct ceph to place 3 daemons
ceph orch apply mgr 3 --placement="cephstage01:10.20.20.81,cephstage02:10.20.20.82,cephstage03:10.20.20.83"
but
root@cephstage01:/# ceph -s cluster: id: 0827effc-302a-45a6-bb97-758d2a9e6835 health: HEALTH_ERR Failed to apply 6 service(s): alertmanager,grafana,mgr,mon,node-exporter,prometheus failed to probe daemons or devices 2 mgr modules have failed 1 mgr modules have recently crashed OSD count 0 < osd_pool_default_size 3

and when I check those hosts
root@cephstage01:/# ceph cephadm check-host cephstage03 cephstage03 (None) ok docker (/usr/bin/docker) is present systemctl is present lvcreate is present Unit chrony.service is enabled and running Hostname "cephstage03" matches what is expected. Host looks OK
they look fine.
every time I recreate the cluster it gives me the same errors: does anybody have any idea?
thanks in advance
