Description

Currently, We can reserve space on a volume using hdds.datanode.dir.du.reserved, which is key-value pair where we specify the volume and the space that should be reserved in that volume (i.e data1:5000MB). If there are multiple volumes we have put a key-value pair of volume:reserved for each volume. This JIRA aims to create a configuration that sets the percentage of volume reserved for all the volumes in the Datanode.
