The ranges allocated are: >>> 0xffffffff - 0xaaa972d0 1431735599 >>> 0xaaa972cf 2863231695 Though the ranges are in the ratio 1:2, they are allocated to wrong bricks. Large range is allocated to smaller brick. Need to fix it. http://review.gluster.org/15403 posted upstream for review. Upstream mainline : http://review.gluster.org/15403 Upstream 3.8 : http://review.gluster.org/15422 downstream patch : https://code.engineering.redhat.com/gerrit/#/c/84881/ Verified this BZ with glusterfs version: 3.8.4-3.el7rhgs.x86_64. Here are the steps that were performed, 1) Created a distribute volume using one brick of 100GB . 2) Mounted it on the client using FUSE and created directory and 1000 files. 3) added brick of 200GB from the another node and ran the rebalance from the same node. Rebalance is considering the brick sizes while setting the layout, where large range is allocated to a large brick and a smaller range to a small brick. Hence, moving this BZ to Verified.
