Very strange. I tried it on new files and even went to the extent of
deleting the datastore and bricks, then recreating.

One oddity on my system - I have two prefs that I cannot reset
- cluster.server-quorum-ratio
- performance.readdir-ahead

Though I would'nt have thought they made a difference. I might try cleaning
gluster and all its config files off the systems and *really* starting from
scratch.

Sure. So far I've just been able to figure that GlusterFS counts blocks in
multiples of 512B while XFS seems to count them in multiples of 4.0KB.
Let me again try creating sparse files on xfs, sharded and non-sharded gluster
volumes and compare the results. I'll let you know what I find.
