setting quota limits for a file system, replication within the file system should be considered. GPFS quota management takes replication into account when reporting on and determining if quota limits have been exceeded for both block and file usage. In a file
system that has either type of replication set to a value of two, the values reported on by both the mmlsquota command and the mmrepquota command are double the value reported by the ls command."</span></div>

<br>
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>
