<p class="MsoNormal"><span lang="EN-US">I agree that there are still sites running Lustre 1.8.x in production, but I don’t think that it is a reasonable assumption that 2.7 or newer isn’t safe yet – I think that most vendors (including your employer
</span><span lang="EN-US" style="font-family:"Apple Color Emoji"">😉</span><span lang="EN-US"> ) are shipping something based on 2.7 or newer. My gut feeling is that if the usage survey was conducted today rather than six months ago that 2.10.x would come out
as the clear leader (rather than being tied with 2.5.x). It’s also still possible to get support for older releases, but the matrix was “cleaned up” recently because the volume of information there made it hard for people to find the most current info, which
is what most visitors were looking for. I’m fine to alter it again if there is demand to do so.<o:p></o:p></span></p>
