<p>Hello,</p>
<p>since the early days of GPFS there was a limitation of using only
integer values in the LIMIT directive for placement policy rules.</p>
<p>Now it seems outdated and GPFS documentation says "You can
specify
<span class="ph synph"><span class="ph var">OccupancyPercentage</span></span>
as a floating point number , as in the following
example:</p>
<p>RULE 'r' RESTORE to pool 'x' limit(8.9e1)<br>
</p>
<p>However, 8.9e1 = 89, and I'm wondering if it is acceptable to
define limit 99.5% in file placement policy like this:<br>
</p>
<p>RULE 'DATA3' SET POOL 'data2' LIMIT(99.5)</p>
<p>mmchpolicy does not complain to such values. My doubt is if GPFS
really uses fractions of a percent in occupancy calculation.</p>
<p>Is anybody using such limits?<br>
</p>
<p>(0.5% in my case make a difference because it corresponds to
about 60TB)</p>
<p>Thanks,</p>
<p>Vladimir<br>
