<div class="">Hello all,<br class="">
<br class="">
I recently discovered some mismatches in our /etc/modprobe.d/ko2iblnd.conf files between our clients and servers.<br class="">
<br class="">
Is it now recommended to keep the defaults on this module and run without a config file or are there recommended numbers for lustre-2.15.X?<br class="">
<br class="">
The only thing I’ve seen that provides any guidance is the Lustre wiki and an HP/Cray doc:<br class="">

Anyone have any sage advice on what the ko2iblnd.conf (and possibly ko2iblnd-opa.conf and hfi1.conf as well) on modern systems?<br class="">

<div>It would be useful to know what specific settings are mismatched. Definitely some of them need to be consistent between peers, others depend on your system.</div>
