<p>I forgot to mention some subtle details:<br>
- This is a ZFS-backed Lustre filesystem.<br>
- There is nothing present in the <font
face="Courier New, Courier, monospace"><i>.lustre</i></font>
directory.<br>
<br>
We have DoM enabled, and it seems the discrepancy comes from the
MDTs:<br>
<br>
<font face="Courier New, Courier, monospace"><i>lfs quota -v -uh
username /mnt/lustre/<br>
<br>
Disk quotas for usr username (uid 101559):<br>
Filesystem used quota limit grace
files quota limit grace<br>
/mnt/lustre/ 970.1M 0k 0k -
22 0 0 -<br>
lustreFS-MDT0000_UUID 282.7M - 0k
- 6 - 0 -<br>
lustreFS-MDT0001_UUID 188.1M - 0k
- 4 - 0 -<br>
lustreFS-MDT0002_UUID 499.4M - 0k -
10 - 0 -<br>
lustreFS-MDT0003_UUID 1k - 0k
- 2 - 0 -<br>
lustreFS-OST0000_UUID 0k - 0k
- - - - -<br>
lustreFS-OST0001_UUID 0k - 0k
- - - - -<br>
...</i></font><br>
<br>
Before bringing down the filesystem and taking a look at what ZFS
quota reports, it would be good to know<br>
whether Lustre performs any manipulation or if it more or less
directly reports what ZFS quota accounting returns.<br>
<br>

<p>Hi all,<br>
<br>
We are seeing a discrepancy between what <font
face="Times New Roman, Times, serif"><i>lfs quota</i></font>
reports and what we can locate using <font
face="Times New Roman, Times, serif"><i>lfs find</i></font> or
the standard <font face="Times New Roman, Times, serif">find</font>
command.<br>
For example:<br>
<br>
<font face="Times New Roman, Times, serif"><i>lfs quota -uh
username /mnt/lustre/<br>
<br>
Disk quotas for usr username (uid 101559):<br>
Filesystem used quota limit grace files
quota limit grace<br>
/mnt/lustre/ 970.1M 0k 0k -
22 0 0 -<br>
<br>
uid 101559 is using the default block quota setting <br>
uid 101559 is using the default file quota setting</i></font><br>
<br>
<br>
However, neither <i><font face="Times New Roman, Times, serif">lfs
find -user username</font></i> nor the standard <i><font
face="Times New Roman, Times, serif">find</font></i> command
can locate these 22 files.<br>
Running <i><font face="Times New Roman, Times, serif">lfsck</font></i>
has no effect and produces the same result.<br>
<br>
We have observed this behavior on Lustre 2.15.6 and continue to
see it on 2.15.7 and 2.15.8.<br>
The example user’s access was revoked before any file search was
performed.<br>
<br>
Does anyone have an idea how to locate or clean up these ghosted
files, or how to fix the quota reporting discrepancy?<br>
<br>
<br>
Best,<br>
Rasool<br>
