about the Lustre code robust on Arm64, we’d planned to implement the Lustre patch landing CI. The idea is to run the Arm64 RPM build and the whole test suite when the patch in gerrit is +2 and cherry pick to the master branch.</span></div>

<span style="font-size: 14px;" class="">One problem with waiting until a patch is +2 is that this will make it more difficult for developers to notice that there is a problem with aarch46 testing. This also adds significant overhead to the development process,
since any aarch64-specific bug found in the patch that needs to be fixed will invalidate all of the previous review and testing efforts.</span></div>
<div><span style="font-size: 14px;" class=""><br class="">
</span></div>
<div><span style="font-size: 14px;" class="">My preference would be to "opportunistically" run tests against patches when they are pushed, as test nodes become available, and then post results on the patch in case of test failure, maybe also in case of success
if there are only a few lines. This is what we do with "optional" test sessions in autotest when we add new/experimental test configurations (new distro or architecture). The "optional" sessions do not mark a patch with Verified: -1, and do not need to be
re-run if they fail, but at least allow tracking pass/fail results in Maloo, and allow eventually enforcing those sessions when they are passing consistently. </span></div>
<div><span style="font-size: 14px;" class=""><br class="">
</span></div>
<div><span style="font-size: 14px;" class="">While "optional" sessions may not run on every patch, they at least run as many tests as possible (keeping test nodes busy) and with good patch monitoring it is possible to prioritize running sessions on new patches
(that have never had a previous test run), and new versions of patches that previously failed testing. A lower priority would be patches that have already run aarch64 testing and passed.</span></div>
<div><span style="font-size: 14px;" class=""><br class="">
</span></div>
<div><span style="font-size: 14px;" class="">The contrib/scripts/gerrit_checkpatch.py script can be used as an example of monitoring Gerrit for new patches/versions, and tracking which patches have already been processed. </span></div>
