> Currently, the datanode can detect slow disks. See HDFS-11461.
> And after HDFS-16311, 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.
