ceph.conf includes:

[client.2]
    rgw region = bar
    rgw zone = bar-secondary
    rgw region root pool = bar.rgw.root
    rgw zone root pool = bar-secondary.rgw.root

If the pool names are changed to be prefixed by a '.', the command succeeds.
radosgw-admin should not crash, but tell the user the requirements of a pool name.
This needs documentation as well. Nothing else depends on particular pool name contents.
