Extending the Size of Static Partition and Automating LVM with Python Script

Image
So what is Partitioning of Hard Disk? Partitioning is the concept in which the disk is divided into different segments of secondary storage as a result of easy management of segments separately. Partition is also be performed to reduce the chance of data loss as if 1 segment also of the partition fails then the entire partition data is getting lost. So we create more partition to reduce the loss of the data. In this article 1: Static Partitioning →First, we will make a static partition using →further, we will extend that created static partition without loosing data 2: Dynamic Partitioning: →Then we will automate LVM concepts with the help of Python Scripts

Adding Elasticity in Hadoop Datanode Using LVM

  So what is Hadoop? Apache Hadoop is an open-source software used for maintaining the environment of distributed storage and computing cluster, as in real life we need storage in real used we need storage which is not possible to provide by a single storage device, so here Hadoop comes into play which combines all its slave node storage and creates an illusion so that client feels a lot of storage in a single device. Hadoop is mainly used for achieving greater computational at a reduced cost. So what is LVM? LVM is a tool for logical volume management that allows us to create dynamic storage units that can be resized as per our needs without worrying about the issues of data leakage. Everything is done by a single command. In this article, Firstly we would be creating a physical volume. Next, we would create the volume groups. Next, we will use the volume group as a storage device we will create a logical volume from it and format it as we do always with the partition. We would th...

Automation Using Python Menu-Driven Program

Image
  Automation is the key to the future, as in industry we don't want any delay in providing service to the client and the implementation of automation technologies, techniques and processes improve the efficiency, reliability of many tasks that were previously performed by humans manually. Today almost all the organization are using automation in their system and keeps on increasing on daily basis both in the software/hardware and machine layer. In this article, we will see how automation reduces human effort and how the menu-driven program functions.
