Hello,
i get:
[WRN] CEPHADM_HOST_CHECK_FAILED: 6 hosts fail cephadm check
host ceph01 failed check: Failed to connect to ceph01 (ceph01).
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@ceph01
host ceph02 failed check: Failed to connect to ceph02 (10.10.1.2).
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@ceph02
host ceph03 failed check: Failed to connect to ceph03 (10.10.1.3).
Check that the host is reachable and accepts connections using the
cephadm SSH key
you may want to run:

host ceph04 failed check: Failed to connect to ceph04 (10.10.1.4).
Check that the host is reachable and accepts connections using the
cephadm SSH key
you may want to run:

host ceph05 failed check: Failed to connect to ceph05 (10.10.1.5).
Check that the host is reachable and accepts connections using the
cephadm SSH key
you may want to run:

host ceph06 failed check: Failed to connect to ceph06 (10.10.1.6).
Check that the host is reachable and accepts connections using the
cephadm SSH key
on ceph01 i run:
ceph cephadm get-ssh-config > /tmp/ceph.conf
ceph config-key get mgr/cephadm/ssh_identity_key > /tmp/ceph.key
chmod 600 /tmp/ceph.key
ssh -F /tmp/ceph.conf -i /tmp/ceph.key root@ceph01 (which works)
So i can not understand the errors above.
