If you are going to use Swift for cloud-wide secondary storage, you must add the Swift storage to CloudStack before you add the local zone secondary storage servers. See <a class="xref" href="zone-add.html">Section 7.2, “Adding a Zone”</a>.

Now that the secondary storage server for per-zone storage is prepared, add it to CloudStack. Secondary storage is added as part of the procedure for adding a new zone. See <a class="xref" href="zone-add.html">Section 7.2, “Adding a Zone”</a>.
