For example, reserved space for RAM_DISK storage can be configured using property
'dfs.datanode.du.reserved.ram_disk'. If specific storage type reservation is not configured
then dfs.datanode.du.reserved will be used.
+ Note: In case of using tune2fs to set reserved-blocks-percentage, or other filesystem tools,
+ then you can possibly run into out of disk errors because hadoop will not check those
+ external tool configurations.
