Increasing the HDFS Disk size in HDP 2.3 3 node cluster

[#1]

In the 3 node cluster installation for POC, My 3rd note is datanode, it has a disk space of about 200 GB.

As per the widget, my current HDFS Usage is as follows:

DFS Used: 512.8 MB (1.02%); non DFS used 8.1 GB (16.52%); remaining 40.4GB (82.46 %)

When I do df -h to check the disk size i can see a lot of space is taken by tmpfs as shown in the following screenshot:

How can I increase my HDFS disk size?
