Hi, Installing Ceph Octopus using cephadm. I managed to install ceph-common with cephadm and when trying to add new hosts with "ceph orch host add ceph2" I get error "Error EINVAL: Failed to connect to ceph2 (ceph2). Check that the host is reachable and accepts connection using the cephadm SSH key". I verified that I am able to ssh login to the ceph2 server with ceph private_key like it was described in the error message. But since adding new hosts to the ceph wasn't working, I tried generating the new private key and updating the public keys to the remote servers with: # ceph cephadm clear-key # ceph cephadm generate-key # ceph cephadm get-pub-key > ceph.pub # ceph config-key get mgr/cephadm/ssh_identity_key > ceph.priv # ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph1 # ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph2 # ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph3 And then testing that the private key really is working: # chmod 600 ceph.priv # ssh -i ceph.priv root@ceph2 At this point ssh works with passwordless login. But still the ceph orch host add ceph2 doesn't work (giving exactly the same error) I also tried restarting the manager with "ceph mgr fail" which was informed somewhere -> no effect. Also tried rebooting the machines -> no effect. Any tips I could still try ? Thank you very much! _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
