[Gluster-users] Shard file size (gluster 3.7.5)

[Lindsay Mathieson]

I can reproduce this 100% reliably, just by coping files onto a gluster
volume. Reported File size  is always larger, sometimes radically so. If I
copy the file again, the reported file is different each time.

using cmp I found that the file contents match, up to the size of the
original file.

MD5SUMS probably differ because of the different file sizes.
