The rebalance status show 0 Bytes.
Maybe you should try with the 'gluster volume rebalance <VOLNAME> start force' ?

All,RHEL 7.5Gluster 3.8.152 Nodes: serverA & serverBI am not deeply knowledgeable about Gluster and it's administration but we have a 2 node cluster that's been running for about a year and a half. All has worked fine to date. Our main volume has consisted of two 60TB bricks on each of the cluster nodes. As we reached capacity on the volume we needed to expand. So, we've added four new 60TB bricks to each of the cluster nodes. The bricks are now seen, and the total size of the volume is as expected:# gluster vol status tank

localhost:/tank 355T 116T 239T 33% /mnt/tankWe were thinking that the used space would be distributed across the now 6 bricks after rebalance. Is that not what a rebalance does? Is this expected behavior?Can anyone provide some guidance as to what the behavior here and if there is anything that we need to do at this point?Thanks in advance,HB
