Subject: [lustre-discuss] Lustre QoS using TBF<br>
Message-ID:<br>

Dear community,<br>
<br>
We at the university of Groningen (the Netherlands) are looking into doing<br>
QoS on our Lustre file system to prevent users from suffocating our<br>
filesystems. Lustre QoS using TBF is mentioned in a couple of<br>
presentations/slides, but I failed to get/find some useful documentation on<br>
how to implement such a feature.<br>
<br>
My question: Does anybody of you have some experience with Luste QoS in<br>
production you want to share, does it work, and what are best practises?<br>
<br>
