We are using a Distributed-Replicate volume with replica 2 on Gluster 4.1.7 on CentOS 7. One of our nodes died recently and we will add new nodes and bricks to replace it soon. In preparation for the maintenance I wanted to rebalance the volume to make the disk thrashing less intense when we add/remove bricks, but after eight hours of scanning I see millions of "failures" in the rebalance status. The volume rebalance log shows many errors like:

The bricks on the healthy nodes all have 1.5TB of free space so I'm not sure what this error means. Could it be because one of the replicas is unavailable? I saw a similar bug report¹ about that. I've started a simple fix-layout without data migration and it is working fine.
Thank you,
