Are you sure that the bricks which you used for this volume was not having any previous data?
Find out the total number of files and directories on your mount point (recursively) and then see the number of entries on .glusterfs/

Hi,
We are currently experiencing a serious issue w.r.t volume space usage by glusterfs.
In the below outputs, we can see that the size of the real data in /c (glusterfs volume) is nearly 1GB but the “.glusterfs” directory inside the brick (i.e., “/opt/lvmdir/c2/brick”) is consuming around 3.4 GB
Can you tell us why the volume space is fully used by glusterfs even though the real data size is around 1GB itself ?
