I was wondering whether to try that, but that the fix had not<br>
already been applied to 2.16 got me to think that there were<br>
some subtle changes between 2.15 and 2.16 that made it a<br>
difficult operation. But I will try.<br>

There are only so many hours in a day, and we don't port every patch back to b2_15.</div>

<div>BTW I can easily switch to 2.16 except that I cannot yet easily<br>
switch away from EL8, and allegedly 2.16 is not available for<br>
EL8, at least in pre-compiled form:<br>
<br>
https://downloads.whamcloud.com/public/lustre/lustre-2.16.1/<br>
<br>
I can easily rebuild from sources, but I wonder whether there is<br>
some specific incompatibility between 2.16 and the EL8 kernel<br>
and libraries...<br>

<div>The 2.16 code was tested with el8 on a regular basis, but the primary distro that</div>
<div>it is intended to work with is el9.x.</div>
