<p class="MsoNormal">Not using heartbeat (Lustre 1.8.4 manual
section
8.3?). As we've added OSS, we've never explicitly placed the
machine
names in any configuration. <br>
<br>
Furthermore, no IP changes will be made, just the DNS name, so
perhaps we are
safe after all?<br>

<p class="MsoNormal" style="margin-bottom: 12pt;">I think that
Andreas got
confused and thought that you want rename OST. <br>
<br>
Renaming OSS is easy and don't require any Lustre
reconfiguration if your
Lustre configuration is based on IP addresses and not
hostnames.<br>
<br>
If you have heartbeat, you need to change names in
configuration<br>
<br>
