This PR https://github.com/ceph/ceph/pull/8975 removes the 'rados cppool' command. The main problem is that the command does not make a faithful copy of all data because it doesn't preserve the snapshots (and snapshot related metadata). That means if you copy an RBD pool it will render the images somewhat broken (snaps won't be present and won't work properly). It also doesn't preserve the user_version field that some librados users may rely on. Since it's obscure and of limited use, this PR just removes it. Alternatively, we could add safeguards so that it refuses to make a copy if there are any selfmanaged_snaps, and/or generate some warnings. Any objections? sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
