Why does the 'ceph osd map' command continue to show removed objects from the cluster?

Issue

• When removing an rbd image from a pool the ceph osd map tool continues to show the test-image object as existing in the cluster. Why is this?

 # rbd create test-image --size 1024 --pool testpool
 # rbd -p testpool ls
 # ceph osd map testpool test-image
 osdmap e141 pool 'testpool' (1) object 'test-image' -> pg 1.fb49053a (1.13a) -> up ([3,4,1], p3) acting ([3,4,1], p3)
 # rbd rm -p testpool test-image
 Removing image: 100% complete...done.
 # ceph osd map testpool test-image
 osdmap e141 pool 'testpool' (1) object 'test-image' -> pg 1.fb49053a (1.13a) -> up ([3,4,1], p3) acting ([3,4,1], p3)

• What does the ceph osd map command actually do?
