<p>My apologies I meant 2.5.34 not 2.6.34. We'd like to get up to
2.10.4 which is what our clients are running. Recently we
upgraded our cluster to CentOS7 which necessitated the client
upgrade. Our storage servers though stayed behind on 2.5.34.</p>

<div>2.6.34 is a kernel version. What version of Lustre are you
at now? Some updates are easier than others.</div>

experience with doing this and if they could share them.
How do you handle upgrades like this? How much time does it
take? What are the pitfalls? How do you manage it with
minimal customer interruption? Should we just write off
upgrading and stand up new servers that are on the correct
version (in which case we need to transfer the several PB's
worth of data over to the new system)?<br>

Thanks for your wisdom.<br>
