Hi, I deployed Openstack with Juju & Maas, the deploy task is success and I can login to openstack dashboard, create volume and attach to instance. The problem is I can't query ceph health or ceph -s on Ceph-osd unit. It show me error with "RADOS object not found (error connecting to the cluster)" when I type ceph command But I can query them on ceph-mon unit . Do I need to do more step to type command ceph on Ceph-osd and other nodes.

Thanks, Ritzttk

Every node you want to be able to query the ceph cluster from needs some kind of keyring (it can also be a read-only client if you just want to query the cluster status), the MON nodes usually have an admin keyring in /etc/ceph/. Compare the contents and copy the file to the OSD node (if really required). The ceph.conf file should already be present.

Thanks, It works . I didn't know about the keyring. This information is very helpful
