</span>What do you mean by this? AFAIK just "adding a network" should not do anything<br>
in itself. If you refer to the section "Storage Network" from that post, then<br>
it describes how to add the existing, pre-configured storage network, to the<br>
engine management, not how to "create" it.<br>

<br>
</span>I'd say the right way is probably to plan beforehand and create your<br>
storage network ahead. Choose nics for that, connect them to a separate vlan,<br>
give them IP addresses, give these addresses names (different from the names<br>
given to addresses of other nics), and use these names when configuring<br>
the gluster storage.<br>

</span>If you provided IP addresses of the wrong nics and now want to change that,<br>
then I have no idea - no personal experience with gluster. Adding Sahina<br>

I suggest, in such cases, to always use names, never IP addresses. It's<br>
a bit more maintenance work (of the dns and/or /etc/hosts), but provides<br>
much more flexibility - if you used names, you can (in principle, didn't<br>
try that myself) take everything down, change the names to point at the<br>
IP addresses of the correct nics, then start all up.<br>
<br>
