Aaron T. Myers commented on HDFS-1564:
--------------------------------------

My understanding is that the requester would like the ability to configure this *independently* per volume. e.g. configure 10GB reserved space for volume /fs1 and 20GB reserved space for volume /fs2.

> Make dfs.datanode.du.reserved configurable per volume

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