If a dist-rep or dist-disperse volume is created on 2 nodes by dividing the bricks equally across the nodes, one process might determine it has no local_subvols. When trying to update the commit hash, the function attempts to lock all local subvols. On the node with no local_subvols the dht inode lock operation fails, in turn causing the rebalance to fail. In a dist-rep volume with 2 nodes, if brick 0 of each replica set is on node1 and brick 1 is on node2, node2 will find that it has no local subvols.
