Introduction to OceanStor 9000 V100R001C01 data balancing

OceanStor 9000 data balancing refers to the balancing of data capacity on storage nodes. After a disk or node is added, you can migrate it to make data evenly distributed on all storage nodes.
OceanStor 9000 provides two modes of data balancing:
- Manual balancing: After a data balancing task is manually started, the system checks whether data in each node pool is balanced in the system. If data is unbalanced, the system starts a data balancing task.
- Automatic balancing: After a disk or node is added, the system waits 30 minutes and then starts a data balancing task. If the waiting time is shorter than 30 minutes and more disks or nodes are added, the system waits another 30 minutes before starting a data balancing task.
