File size as reported on the mount point and the bricks can vary

uint64_t maxblocks;

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?

This is very unlikely the problem. st_blocks field values do not
influence md5sum behavior in any way. The file size (st_size) would, but
both du -k and the above code snipped only deal with st_blocks.
I was referring to du -k as seen on the bricks and the mount point. I
was certainly not referring to the md5sum difference.

Bobby, it would help if you can identify the mismatching file and
inspect and see what is the difference between the two files?

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*
