<p>Hello All,</p>
<p>I setup two fresh and clean Swift clusters on AWS EC2. I follow
the <br>
guide (<a
href="http://docs.openstack.org/developer/swift/overview_container_sync.html">http://<wbr>docs.openstack.<wbr>org/developer/<wbr>swift/overview_<wbr>container_<wbr>sync.html</a>)<br>
to synchronize two containers in these two clusters.<br>
The two containers itself could be synchronized perfectly<br>
(the containers are correctly created at both clusters), <br>
but the data in the two containers are not synchronized <br>
(if I populate some data in a container at one cluster, <br>
the container at the other cluster is always empty)</p>
<p>I also created two Swift clusters in our local data center and
follow<br>
the same procedure to synchronize two clusters. This time, <br>
both containers and data could be synchronized correctly.</p>
<p>So, is there any special setting in EC2 (e.g. security group,<br>
firewall) that will block the data synchronization between <br>
the two clusters?</p>
<p>Thanks,</p>
<p>Ning<br>
</p>
