Konstantin Shvachko commented on HDFS-1564: ------------------------------------------- dfs.datanode.du.reserved is per volume. Here is the description from hdfs-default.xml: {code} <property> <name>dfs.datanode.du.reserved</name> <value>0</value> <description>Reserved space in bytes per volume. Always leave this much space free for non dfs use. </description> </property> {code} Also if you look in the code the property is used in FSVolume, which corresponds to one volume. Or do I miss what this is about? > Make dfs.datanode.du.reserved configurable per volume > ----------------------------------------------------- > > Key: HDFS-1564 > URL: https://issues.apache.org/jira/browse/HDFS-1564 > Project: Hadoop HDFS > Issue Type: New Feature > Components: data-node > Reporter: Aaron T.
