Yes, this correct (I think there was some discussion on the mailing list a little while back).<br>
<br>
The quota is the space used on disk, so if you run compression its the compressed size, tape hsm don't count until you recall them.<br>
<br>
I assume mcstore is the same, I.e. Only counts on recall, but I haven't tested this.<br>

<p class="MsoNormal">Hi again all,</p>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I have another question on a completely different topic and therefore I decided it was better to send two separate e-mails.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">For a number of years now we have had a GPFS filesystem where we use filesets and set fileset quotas. Data replication is set to one. I understand how that all works.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">We are creating another GPFS filesystem where we intend to also use filesets and fileset quotas, but set data replication to two. Based on my experience with data replication on a filesystem that doesn’t use filesets, I am expecting that
setting data replication to two means that I will need to double the quota for each fileset (i.e. if a group has bought 5 TB of space I’ll need to set their fileset quota to 10 TB) but haven’t found where that is explicitly documented. Is that correct?</p>
