Other rados put will fail as follows $ touch /tmp/bar $ ./rados -p rbd put existing_3 /tmp/bar $ ./rados -p rbd put existing_3 /tmp/bar WARNING: could not create object: existing_3 error putting rbd/existing_3: (17) File exists it should be considered a bug in the rados command line but needs to be addressed separately. http://tracker.ceph.com/issues/9387 Fixes: #9387 Signed-off-by: Loic Dachary loic-201408@dachary.org
