This code does not belong in ctdb/tools.  You can move it to an appropriate
directory in ctdb/utils.

Please include the test code also as part of the commit.  Someone with
ceph-rados setup should be able to run this test.
I would appreciate if you can add few comments in the test script
describing the requirements and how to run the test.
