Hi Stepan!<br>
<br>
Erasure coding is very much an in-development feature. There's some investigatory work going on by James Simmons at ORNL, and the main development effort is tracked here in JIRA:<br>
<br>
<a href="https://jira.whamcloud.com/browse/LU-10911">https://jira.whamcloud.com/browse/LU-10911</a><br>
<br>
The currently in-development code is here - this is the tip of a fairly long branch:<br>
<a href="https://review.whamcloud.com/c/fs/lustre-release/+/62757">https://review.whamcloud.com/c/fs/lustre-release/+/62757</a></div>
<div style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);" class="elementToProof">
<br>
You can look at the tests in that branch for examples, but note the code is very much in active development. There is a lot of churn and a number of known bugs.<br>
<br>
But if you'd like to follow along, that's where the work is being done. We'd also be happy to have feedback on the API if you're interested in taking a look. (In the code - the API has changed some from what's documented in JIRA)</div>

<div>Hi everyone ! <br>
<br>
</div>
Is there any topics or threads with information about current lustre erasure coding development status and usage examples? If they exist, send links in reply to this message. <br>

Thanks, <br>
