Description

This occurred on a mixed firefly+next cluster with thrashing going on in the background.

It was detected by an rbd test that checks the number of data objects are in an image.

Relevant log excerpt:

2015-01-13T03:56:13.691 INFO:tasks.workunit.client.0.burnupi28.stderr:+ objects=1
2015-01-13T03:56:13.691 INFO:tasks.workunit.client.0.burnupi28.stderr:1
2015-01-13T03:56:13.691 INFO:tasks.workunit.client.0.burnupi28.stderr:+ echo 1 1
2015-01-13T03:56:13.692 INFO:tasks.workunit.client.0.burnupi28.stderr:+ [ 0 -eq 1 -o 1 1 = 1 ]

The '1 1' indicates that there were two objects with the same name (see https://github.com/ceph/ceph/blob/master/qa/workunits/rbd/import_export.sh#L12)

It's unclear if this is meant to be possible, but it could be fixed on the client side easily in librados.
