Hi IoTDBers:

  When I using iotdb-cluster[3 nodes，default_replica_num=1] to manage 300 devices in 20 storagegroups, I hope the data will be evenly distributed.But it's, not.

node1: 2.1T 【7 storage groups】

node2: 3.9T【9 storage groups】

node3: 773G【4 storage groups】

PS：If I use iotdb-single to manage the same data, the data size only 3.0T,but now the cluster used almost 7T.

Please check this.

Thanks.

B.R.
