Hi All,
<div class=""><br class="">
</div>
<div class="">So I’m _still_ reading about and testing various policies for file placement and migration on our test cluster (which is now running GPFS 5).</div>
<div class=""><br class="">
</div>
<div class="">On page 392 of the GPFS 5.0.0 Administration Guide it says:</div>
<div class=""><br class="">
</div>
<div class="">
<div class="page" title="Page 424">
<div class="layoutArea">
<div class="column">
<p class=""><span style="font-size: 10.000000pt; font-family: 'Palatino'" class="">To add a callback, run this command. The following command is on one line:
</span></p>
<pre class=""><span style="font-size: 9.000000pt; font-family: 'BookMaster'" class="">mmaddcallback MIGRATION --command /usr/lpp/mmfs/bin/mmstartpolicy --event lowDiskSpace
--parms "%eventName %fsName --single-instance
</span></pre>
<p class=""><span style="font-size: 10.000000pt; font-family: 'Palatino'" class="">The
</span><span style="font-size: 10.000000pt; font-family: 'Palatino'; font-weight: 700" class="">--single-instance
</span><span style="font-size: 10.000000pt; font-family: 'Palatino'" class="">flag is required to avoid running multiple migrations on the file system at the same time. </span></p>
<div class="">However, trying to issue that command gives:</div>
<div class=""><br class="">
</div>
<div class="">mmaddcallback: Incorrect option: --single-instance</div>
<div class=""><br class="">
</div>
<div class="">And the man page for mmaddcallback doesn’t mention it or anything similar to it. Now my test cluster is running GPFS 5.0.1.1, so is this something that was added in GPFS 5.0.0 and then subsequently removed?</div>
<div class=""><br class="">
</div>
<div class="">I can’t find the GPFS 5.0.1 Administration Guide with a Google search.</div>

<div class="">Thanks…</div>
