- 'rbd ls' on a pool which never held rbd images now exits with code
0. It outputs nothing in plain format, or an empty list in
non-plain format. This is consistent with the behavior for a pool
which used to hold images, but contains none. Scripts relying on
this behavior should be updated.
- The MDS requires a new OSD operation TMAP2OMAP, added in this release. When
upgrading, be sure to upgrade and restart the ceph-osd daemons before the
ceph-mds daemon. The MDS will refuse to start if any up OSDs do not support
the new feature.
