PFL layout don't inherit correctly from default layout.

Bug Blocker Open Unresolved WC Triage Alexey Lyashkov Thu, 8 Aug 2019 11:34:56 +0000 Sat, 28 Dec 2019 08:11:19 +0000 Lustre 2.12.0 0 5 <p>It seems like this might be a duplicate of <a href="https://jira.whamcloud.com/browse/LU-11656" title="&quot;lfs getstripe&quot; on directory does not show default root layout" class="issue-link" data-issue-key="LU-11656"><del>LU-11656</del></a>? </p> <p>One problem is that "<tt>lfs getstripe /mnt/dir/testdir</tt>" does not print the layout from the root directory if <tt>testdir</tt> does not have an explicit copy of the default directory layout, even though files created in that directory will inherit the default layout from the root directory. </p> <p>The reason that 2.12/master <em>seems</em> broken is that <a href="https://jira.whamcloud.com/browse/LU-11739" title="Don&#39;t inherit default layout from root for new subdirectories" class="issue-link" data-issue-key="LU-11739"><del>LU-11739</del></a> stopped explicitly copying the default layout from the root directory for files created under root. That is an improvement, because if the root directory layout is changed, we don't have to go around and copy the new default layout to hundreds or thousands of existing directories that made an explicit copy. </p> <p>In your above examples, please try creating a file under <tt>testdir</tt> to see if the layout is properly inherited. Conversely, change the filesystem default layout on the root directory and create a second file. 2.12 should correctly use the new default, while 2.11 will incorrectly use the old default.</p> <p>The correct solution here is to fix <a href="https://jira.whamcloud.com/browse/LU-11656" title="&quot;lfs getstripe&quot; on directory does not show default root layout" class="issue-link" data-issue-key="LU-11656"><del>LU-11656</del></a>, so that "<tt>lfs getstripe -d /mnt/lustre/testdir</tt>" correctly gets the default layout from the root directory.</p> <p>Shadow, any update on this ticket? The <a href="https://jira.whamcloud.com/browse/LU-11656" title="&quot;lfs getstripe&quot; on directory does not show default root layout" class="issue-link" data-issue-key="LU-11656"><del>LU-11656</del></a> patch has landed, so master should show the proper default layout for subdirectories.</p> Related LU-11656 LU-11739 Development Rank 1|i00kw7: Rank (Obsolete) 9223372036854775807 Severity
