    Possibly.  I don&#39;t think changing shard size on the fly is
    supported, especially when there are files on the volume that are
    sharded with a different size.<br>

              - Pending self-heals in gluster (check if `gluster volume

              if there is anything under `.glusterfs/landfill` folder of

              - 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

                          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>
