This snippet was brought in to improve accounting behaviour for quota that would fail with disk file systems that perform speculative pre-allocation.<br>

If this aides only specific use cases, I think we should make the behaviour configurable.<br>

Thoughts?<br>

Subject: [Gluster-users] FileSize changing in GlusterNodes<br>

Hi,<br>
<br>
When I upload files into the gluster volume, it replicates all the files<br>
to both gluster nodes. But the file size slightly varies by (4-10KB),<br>
which changes the md5sum of the file.<br>
<br>
Command to check file size : du –k *. I’m using glusterFS 3.3.1 with<br>
Centos 6.4<br>
<br>
This is creating inconsistency between the files on both the bricks. ?<br>
What is the reason for this changed file size and how can it be avoided. ?<br>
<br>
Thanks & Regards,<br>
<br></div></div>
