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

disk performance about half in domU? + question about XenSource
Based on some tests we ran, it seems the biggest performance
hit you get from running within domU is from disk I/O. We
did some mysql read and write tests, and for both, our
performance is about half that compared to native. Has that
been others'' experience?
Is there any way to make this better? We are using physical
partitions. In contrast, cpu/memory tests appear to be near

[PATCH nbdkit] tests: xz: Use 16M block size when preparing disk for xz plugin test.
In a recent commit guestfish changed the default size for disk images
prepared using the -N parameter from 100M to 1G:
https://github.com/libguestfs/libguestfs/commit/adc23829e4b128562c2c29d984654528bd259644
For the xz plugin test we prepared a disk image using guestfish and
then xz-compressing the output, but we did not take our own advice and
use the --block-size parameter to limit the xz
