I think keyring is fine, as i can run other commands like: rbd ls --pool rbd --name client.admin archiveadmin and was able to create the image rbd info archiveadmin --pool rbd --name client.admin rbd image 'archiveadmin': size 4096 MB in 1024 objects order 22 (4096 KB objects) block_name_prefix: rb.0.2c68.2ae8944a format: 1 From: Karan
