<div>I am looking at the patch to ROMIO to support the new Progressive File</div>
<div>Layout feature:</div>
<div><br>
</div>
<div><a href="https://jira.whamcloud.com/browse/LU-9657">https://jira.whamcloud.com/browse/LU-9657</a></div>
<div>and</div>
<div><a href="https://review.whamcloud.com/#/c/27869/10">https://review.whamcloud.com/#/c/27869/10</a></div>
<div><br>
</div>
<div>This change greatly reworks ROIMIO's support for determining striping count and stripe size. I'm all for using the 'llapi_layout' routines instead of bare ioctl() calls, but llapi_layout did not show up until 2.7 I think.</div>
<div><br>
</div>
<div>Is there any chance that some enviroment out there is still running a</div>
<div>lustre from 2014 or earlier?</div>
<div><br>
</div>
<div>Nothing before 2.10 shows up in the "community matrix"</div>

<div>but I do see some fairly old versions in the "intel releases"</div>
