Subject [jira] Commented: (HDFS-1564) Make dfs.datanode.du.reserved configurable per volume
Date Tue, 04 Jan 2011 21:50:48 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12977473#action_12977473
] 

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?

> In clusters with DNs which have heterogeneous data dir volumes, it would be nice if dfs.datanode.du.reserved
could be configured per-volume.
