Integrating LVM with Hadoop and providing Elasticity to DataNode Storage

Displaying total disks available in the node. The LVM is performed on sdb and sdc.

Step -1

Creating Physical Volume (PV) for sdb and sdc

Step-2

Creating Volume Group (VG) from the PVs created earlier

Step-3

Creating Logic Volumes (LV) from the Volume Group

Step-4

The LV created should be formatted so that it can be used

Step-5

This is the Hadoop cluster report before mounting LV

Step-6

The LV can be used after it is mounted

Step-7

Now we can see an increase in storage, this is from LV

Step-8

The LV is extended without any interruption in the cluster

Step-9

We  can again see an increase in the storage size of the cluster
