</code>

====== Troubleshoot ======


Seems that installation command:
<code bash>
ceph-deploy install --rgw ${THEHOSTNAME} --repo-url https://download.ceph.com/rpm-hammer/el7/
</code>
Does not install ''ceph-radosgw'' package...

====== Solution ======

<code bash>
 yum install ceph-radosgw
</code>

Then it works:
<code bash>
ceph@bvmld-osadm-101 ~/ceph-deploy :( $ ceph-deploy rgw create ${THEHOSTNAME}
