There is a Slack channel, which is linked from <a href="http://wiki.lustre.org" target="_blank">wiki.lustre.org</a> "lists" page that you can use for simple discussions. Email is probably better for complex questions.

I'm currently looking into LU-7880. Will follow up if I have an implementation plan or run into any questions (quite likely).<br>
<br>
By the way, should I reach out to the lustre-devel for questions like this, or is there a more specific channel?<br>

<div>Thanks!</div>

<div>Hi George,
<div>thanks for your interest. There are definitely a number of open tickets in the "easy" (and "medium") categories that you could work on, though there have been a number of interns and new hires working on those tickets recently and fewer are now available.</div>
<div><br>
</div>
<div>LU-1643 happens to be the oldest "easy" ticket, but don't let that guide your selection. I would suggest you take a look through the whole list and pick something that is of interest to you and/or matches your experience level.</div>
<div><br>
</div>
<div>- <a href="https://jira.whamcloud.com/browse/LU-16738" id="m_-4661364368212878897m_1429994837881312626key-val" rel="75582" target="_blank">LU-16738</a> - <a href="https://jira.whamcloud.com/browse/LU-16738" target="_blank">Improve mount.lustre with many MGS NIDs</a>: this is
partly a userspace (mount.lustre) change and partly in the kernel (though not incredibly complex). This is actually in the "useful" category that provides improved functionality for something that is seen regularly.</div>
<div><br>
</div>
<div><br>
</div>
<div>If you are feeling more adventurous, you might look at one of the "medium" tickets, which may not be too difficult:</div>
<div>- <a href="https://jira.whamcloud.com/browse/LU-7880" target="_blank">LU-7880</a> - <a href="https://jira.whamcloud.com/browse/LU-7880" target="_blank">add OST/MDT performance statistics to obd_statfs</a>: this is a very useful feature that would allow
clients/user applications to probe the IO load on OSTs, and self-optimize checkpoint IO to times when the OSTs are less busy</div>
<div>- <a href="https://jira.whamcloud.com/browse/LU-13123" target="_blank">LU-13123</a> - <a href="https://jira.whamcloud.com/browse/LU-13123" target="_blank">Add list of client NIDs to job_stats output</a>: this would associate all of the clients that are
contributing to the job_stats for a specific JobID, and would be useful for debugging and monitoring/<br id="m_-4661364368212878897m_1429994837881312626lineBreakAtBeginningOfMessage">

<div>I'm a storage engineer and a Lustre beginner who just figured out how to deploy it. Did read a lot about it though.</div>
<div>My goal is using Lustre to support HPC/ML workload. And I believe doing some tasks would help me proceed better.</div>
<div><br>
</div>
<div>As wiki suggested, I found an "easy" ticket LU-1643: “Request to remove display of reserved space from statfs (df) total space.”</div>
<div>Is it still unclaimed? </div>
<div>If it's already in progress, or there's a higher priority issue that could use help, please point me in the right direction.</div>
<div><br>
</div>
<div>Thanks in advance for any advice.<br>
<br>
Best regards,</div>
