<html><head></head><body>As long as you use hostnames for your bricks, just change the hostname to resolve to the address you want to use. That's why we always recommend using hostnames.<br>
<br>
If you use IPs, then you're stuck and have to hack files to change bricks.<br><br><div class="gmail_quote">On July 12, 2014 1:03:08 AM PDT, Attila Heidrich <attila.heidrich@gmail.com> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

</div></div>If you want clients to use the 1G links, and servers to talk via the 10G links,<br />
'ip route add <dest> src <1G address> dev <10G interface>' on all server might help.<br /></blockquote><div><br /></div></div><div>Will that not cause asymmetric flows? The traffic will leave via the 10GbE interface, but the destination IP is still the 1GbE interface, so it will arrive at the 1GbE interface on the other host.</div>
<div><br /></div><div>You can change the /etc/hosts entries, replacing the entries for the 1GbE IP with the 10GbE IP and then restarting the gluster processes.</div><div><br /></div><div>You could mess about with iptables and NAT, but I think at that point you might as well add/remove the hosts.</div>
<div><br /></div><div>I guess you can also update the configuration files under /var/lib/glusterfs and rename the brick files... You might want to test that first though :)</div><div><br /></div><div>Cheers</div><div><br /></div>
