<p>Hi all.</p>
<p>I have a GFS2 cluster of three machines using an iSCSI disk.<br>Everything went fine on the initial tests and the cluster seems to work just<br>great.<br>A couple of days ago I submitted this cluster to a number of file creation<br>
operations and whilst this was providing enough load to see some performance<br>data it was also inadvertently deleting some of the files being created for<br>the purpose of the test whilst these files were still being written to.</p>
<p>I though this shouldn't be a problem and that a simple fsck would be able to<br>recover the space lost on those inodes.<br>But that doesn't seem the case and I'll show why.</p>

<p> </p>
<div>As you can see by du's output there's only 101G being used and df's<br>reporting the FS to be 100% used.<br>I've run fsck.gf2 several times on one box on all the boxes but it just<br>doesn't seem to be fixing this right.<br>
It reminds me of a post I saw<br><a href="https://bugzilla.redhat.com/show_bug.cgi?id=325151">https://bugzilla.redhat.com/show_bug.cgi?id=325151</a> .</div>
<div><br>When I ran the first fsck I did saw a lot of issues being fixed and I could<br>almost swear that the first time I mounted the cluster FS after repairing it<br>was reporting the right size again.<br>The next time I mounted it it all reverted back to what I show above.</div>
<p>I'm using</p>
<p>[root@vmcluster1 gfs]# gfs2_tool version<br>gfs2_tool 0.1.44 (built Jul 6 2008 10:57:30)<br>Copyright (C) Red Hat, Inc. 2004-2006 All rights reserved.</p>
<p>Anyone with a similar issue ?!</p>
<p>Cheers,</p>
