Hi, what do you get when you run a 'ceph auth list' command for the user name (client.cinder) you created for cinder? Are the caps and the key for this user correct? No typo in the hostname in the cinder.conf file (host=) ? Did you copy the keyring to the cinder running cinder (can’t really say from your output and there is no ceph-s command to check the monitor names)?
It could just be a typo in the ceph auth get-or-create command that’s causing it.
