Volume Management in Linux with LVM
In this module, we are going to step you through the process of managing LVM, the Logical Volume Management system universally available in Linux. We will be using Ubuntu, CentOS and Arch Linux to ensure that you will be able to follow the exercises on your own system. LVM is a core component of any Linux distribution and makes up certification objectives from the LPI LPIC-1 and LPIC-2 exams as well as the LFCS and RHCE exams. Being such a vital component to Linux LVM2 is also a very important topic to know regardless of any certification. With this in mind, we will cover LVM2 from the very basics through to more advanced topics. Ensuring that you have all the knowledge that you need to be able to work with LVM2 as a true professional.
Should you be working through the labs by yourself having a Ubuntu 16.04, CentOS 7 or Arch 2017 system will be useful. To be honest, other than the installation the commands are consistent across distributions. To complete the exercises we create and use raw files as disk. This means that you can complete the exercises without the need of additional disks being added to your system.
The course is targeted at those wishing to learn more about the Linux Logical Volume Management System, and who have a knowledge and interest in Linux System Administration. The module is focused around the Linux command line so those wishing to complete the course should be con dent in working at the Linux CLI.
By the end of this module you will be able to:
- Configure basic and advance LVM2 disk arrays
- Configure Logical Volume Management volumes from disks, partitions and raw files
- Set metadata options for Logical Volume Management volumes
- Relocate data across Physical Volumes
- Mirror data with Logical Volume Management system
- Create data snapshots with LVM2
- Use LVM2 thin-provisioning
- List and restore previous configurations
