<p>Hi everyone,</p>
<p>In <a href="https://jira.hpdd.intel.com/browse/LU-8940">LU-8940</a>
I describe an issue I am having with <font size="+1"><tt>df</tt></font>
in Lustre's tests. In short, <font size="+1"><tt>df</tt></font>/<font
size="+1"><tt>statfs</tt></font> can report outdated information
about a Lustre filesystem; given enough time, its output gets
correct. From what I understand, <font size="+1"><tt>statfs</tt></font>
cannot report an "always up-to-date" view of the filesystem as
this would cost too much time and resources.</p>
<p> I would like to know what you guys think of having Lustre's <font
size="+1"><tt>statfs</tt></font> operation report a view of the
filesystem <i>at least as new as when the last sync operation
completed</i>?</p>
<p>My point being that users (and tests) would be able to run <font
size="+1"><tt>df --sync</tt></font> to get up-to-date
information (at the cost of a sync operation, and maybe some
accounting for statfs).</p>
<p>Regards,<br>
Quentin<br>
