Repair the damaged disk and make it online again. > 2. Add disks to some Datanodes. > 3. Some disks are damaged, resulting in slow data writing. > 4. Use some custom volume choosing policies. > In the case of unbalanced disk usage, a sudden increase in datanode write > traffic may result in busy disk I/O with low volume usage, resulting in > decreased throughput across datanodes. > We need to find these nodes in time to do diskBalance, or other processing. > Based on the volume usage of each datanode, we can calculate the standard > deviation of the volume usage.
