<div>There is a partially-completed wire protocol document in Git: <a href="https://git.whamcloud.com/?p=doc/protocol.git" class="">

</div>
<div>However, I seriously doubt that it would be sufficient to implement a different client/server than the existing one,</div>
<div>since it is unfortunately both incomplete and already somewhat out of date.</div>
<div><br class="">
</div>
<div>Since Lustre is open-source software, there is little motivation to spend the huge amount of time & effort to</div>
<div>reimplement the client or server. Also, the Lustre protocol changes over time in order to add new functionality,</div>
<div>so a full reimplementation would become obsolete over time without continuous effort equal to all of the other</div>
<div>Lustre developers combined.</div>
<div><br class="">
</div>
<div>It would be better to add/fix/port existing code as needed rather than implementing everything from scratch.</div>
<div>If I might ask, what is your interest in this area? We're always looking to grow the number of developers and</div>
<div>contributors in the Lustre community.</div>
