Ah, okay. Some of the things that can cause a variation in disk
usage:<br>
- Pending self-heals in gluster (check if `gluster volume heal
<volname> info` doesn't show any entries. Also if there is
anything under `.glusterfs/landfill` folder of the bricks).<br>
- XFS speculative preallocation <br>
- Possibly some bug in self-healing of sparse files by gluster
(although we fixed known bugs a long time back in this area).<br>
<br>

<div>Hi all, <br>
<br>
</div>
I have replica 3 with 1 arbiter. <br>
</div>
When checking the gluster volume bricks they are
reported as using different space, as per
attached. How come they use different space? One
would expect to use exactly the same space since
they are replica. <br>
<br>
</div>
</div>

The 3rd brick (arbiter ) only holds meta data, so it would
not consume as much space as the other 2 data bricks. So
what you are seeing is expected behaviour.<br>
