File size as reported on the mount point and the bricks can vary because
of this code snippet in iatt_from_stat():
{
uint64_t maxblocks;
maxblocks = (iatt->ia_size + 511) / 512;
if (iatt->ia_blocks > maxblocks)
iatt->ia_blocks = maxblocks;
}
This snippet was brought in to improve accounting behaviour for quota
that would fail with disk file systems that perform speculative
pre-allocation.
If this aides only specific use cases, I think we should make the
behaviour configurable.
Thoughts?

Subject: FileSize changing in GlusterNodes

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