[Gluster-users] Bricks has different disk usage

I currently have a gluster (glusterfs 3.7.15) volume (distributed-replicated) with 4 bricks (2 x 2 = 4) and the bricks themselves seem to have different usage. I had the impression that they should all be equal?

So all bricks has a 250GB disk. 1 set of bricks (2 bricks) has 91% usage, while the other set (2 bricks) has 16% usage.

So originally, the volume (250GB total) started out with just a set of 2 bricks.  Then 2 more bricks were added to expand the volume to 500GB.  A rebalance was done after adding the new bricks as well as fix-layout.

Really not sure what to make of this.

Details below:

Volume Name: glustervol0
Type: Distributed-Replicate
Volume ID: 243e0652-5b95-4f63-bcf6-f7c60a75ff83
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Brick1: dc1-x-smb-clust-01-1:/vol1/brick1
Brick2: dc1-x-smb-clust-01-2:/vol1/brick1
Brick3: dc1-x-smb-clust-01-1:/vol2/brick2
Brick4: dc1-x-smb-clust-01-2:/vol2/brick2

/dev/xvdb1                         250G  226G   25G  91% /vol1
/dev/xvdc1                         250G   40G  211G  16% /vol2
