<p class="MsoNormal">Hi,<br>
<br>
For a fileset with a quota on it, we have mmlsquota reporting 39TB utilization (out of 50TB quota), with 0 in_doubt.<br>
<br>
Running a 'du' on the same directory (where the fileset is junctioned) shows 21TB usage.<br>
<br>
I looked for sparse files (files that report different size via ls vs du). I looked at 'du --apparent-size ...'<br>
<br>
<a href="https://en.wikipedia.org/wiki/Sparse_file">https://en.wikipedia.org/wiki/Sparse_file</a><br>
<br>
What else could it be?<br>
<br>
Is there some attribute I can scan for inside GPFS?<br>
Maybe where FILE_SIZE does not equal KB_ALLOCATED?<br>
