Ceph » rbd

Ceph Version: 0.48

Created a local directory t_dir.
when tried to import directory t_dir to rbd/rbd_image, it reported error but still created a rbd image, which is not an expected behaviour.

Pasting below the CLI screenshot,

ubuntu@burnupi64:~$ rbd import t_dir rbd/rbd_image
error reading file: (21) Is a directory
Importing image: 0% complete...failed.

ubuntu@burnupi64:~$ rados ls -p rbd
