hello Daniel here Previously i was testing openstack-helm but it doesn't work so i switch to kolla-ansible with all-in-one mode i was following the official guide and put the keyring file i generate to the config folder: (venv) root:~# nano /etc/kolla/config/nova/ ceph.client.nova.keyring ceph.conf localhost/ nova-compute.conf But when i try to deploy it show the error below TASK [nova-cell : Check nova keyring file] ***************************************************************************************************************** fatal: [localhost]: FAILED! => {"msg": "No file was found when using first_found."} Just in case i also put the keyring file in /config/localhost/nova Still shows the same error But when i put the cinder keyring file in nova folder like this: (venv) root@:~# nano /etc/kolla/config/nova/ ceph.client.cinder.keyring ceph.client.nova.keyring ceph.conf localhost/ nova-compute.conf It can find the cinder keyring file but this time the nova-compute container show error below: unable to find a keyring on /etc/ceph/ceph.client.nova.keyring,/etc/ceph/ceph.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin: (2) No such file or directory Did i do anything wrong or something makes it not able to detect the nova.keyring file P.S. Cinder and Glance works fine and Ceph can be used normally
