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. You can change the /etc/hosts entries, replacing the entries for the 1GbE IP with the 10GbE IP and then restarting the gluster processes. You could mess about with iptables and NAT, but I think at that point you might as well add/remove the hosts. 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 :) Cheers > /Anders > > -- > Anders Blomdell Email: [email protected] > Department of Automatic Control > Lund University Phone: +46 46 222 4625 > P.O.
