> Currently, the datanode can detect slow disks. See
> [HDFS-11461|https://issues.apache.org/jira/browse/HDFS-11461].
> And after
> [HDFS-16311|https://issues.apache.org/jira/browse/HDFS-16311[],|http://example.com]%2C/]
> the slow disk information we collected is more accurate.
> So we can exclude these slow disks according to some rules when choosing
> volume. This will prevents some slow disks from affecting the throughput of
> the whole datanode.
