the block sizes would more depend on the file system you're running,
not necessarily the underlying block device (lvm/raid/etc.)
it's possible fc and centos have different defaults for block sizes.
Also, depending on the file system, some will default to different
block sizes depending on the size of the file system, so if these
differ that could account for the difference in reporting.
I don't think it would be du or find that's behaving
differently. I'm using AFR across fc9 32 & fc9 64 bit. with
different device sizes on each end and different block sizes, so I
can't rely on du to be exact.
glad it's all working, in any case :) I was happy with glusters
performance through my recent disaster too.
if you've not already, make sure you list yourself in their "whose
using gluster" wiki, it'll help them get funding so they can continue
their great work.
