This is <a href="https://jira.whamcloud.com/browse/LU-8417">https://jira.whamcloud.com/browse/LU-8417</a> "<span style="background-color: rgba(255, 255, 255, 0);">setstripe -o does not work on directories", which has not been implemented yet. </span>
<div><br>
</div>
<div>That said, setting the default striping to specific OSTs on a directory is usually not the right thing to do. That will result in OST imbalance. <br>
<div><br>
</div>
<div>Equivalent mechanisms include OST pools (which also allow a subset of OSTs to be used, unlike -o currently does), and has the benefit of labeling files with the pool to find them easier in the future (eg. for migrating out of the pool).</div>

</div>
<div>What is the end goal that you are trying to achieve?<br>

<span>Do you get the same error if you try to run this on a file instead of a directory? Also, don’t you typically need to add the “-d” option when setting stripe parameters for a directory?</span><br>
