It might have been added when .lustre was created as a real inode in 2.4 or so?</p> <p>This causes a problem because backup and other filesystem scanning tools will want to go into .lustre and read all the files there, and may also want to restore them after a crash, which could cause problems.</p> <p>I think readdir needs to be fixed to not include the .lustre directory in readdir output.

not include the .lustre directory in readdir output

Shouldn't we wait for some sign that this is causing an issue for some real program before we go adding special cases?</p> <p>&gt;Is this really a problem? Shouldn't we wait for some sign that this is causing an issue for some real program before we go adding special cases?</p> <p>I suppose it means backup and recursive copy tools need to be configured to skip it, but other filesystems have similar "magic" directories that shouldn't be copied, so it's not that odd. I agree it would be simpler to leave it alone. </p> <p>See also <a href="http://review.whamcloud.com/#/c/11186/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/11186/</a>.</p> <p>I'd like to land the 11186 patch to b2_5 so that we can fix <a href="https://jira.whamcloud.com/browse/LU-5955" title="llapi_semantic_traverse() and lfs find skip any child directory named .lustre" class="issue-link" data-issue-key="LU-5955"><del>LU-5955</del></a> on the client.</p> <p>Patch landed to Master.</p> Related LU-5955 Development Rank 1|hzwm9j: Rank (Obsolete) 13937 Severity
