Hello, could you please answer to this question?

A slave node in your cluster has 4 TB hard drives installed (4 x 2TB). The DataNode is configured
to store HDFS blocks on all disks. You set the value of the dfs.datanode.du.reserved parameter to
100 GB. How does this alter HDFS block storage?

Thank in you in advance :slight_smile:

Hi aramil90,

dfs.datanode.du.reserved parameter is set per volume. On every slave node 100 GB space will be reserved for non-dfs use.
