Logical Volume Manager (LVM) is used on Linux to manage hard drives and other storage devices. As the name implies, it can sort raw storage into logical volumes, making it easy to configure and use.

Change Docker root directory /var/lib/docker to another location
By default, Docker stores most of its data inside the /var/lib/docker directory on Linux systems. There may come a time when you want to move this storage space to a new location. For example, the most obvious reason might be that you’re running out of disk space.
Convert ext3 to ext4 in Linux
The ext4 filesystem includes multiple improvements in terms of performance, over its predecessor ext3. Ext4 is not only faster than ext3, but can also handle much larger filesystems and files, and lots of other improvements under the hood. If you haven’t yet upgraded to ext4 on Linux, it’s definitely time to do so.
How to check HDD firmware version in Linux
The command line terminal on Linux systems can give us a lot of insight into the hardware of a computer. Among many other things, we can retrieve the HDD firmware directly by using the Linux command line.
Hard drive hdparm speed test
The purpose of this tutorial is to describe some simple hard drive speed tests that you can perform using your Linux system and the command line tool hdparm.
Linux HDD sleep – how to enable and disable with hdparm
The purpose of this guide is to learn about enable or disable Linux HDD sleep. cover the steps necessary to change a hard drive’s sleep/standby mode timer on Linux. You can either enable standby mode on a storage device, disable standy completely, or adjust the current time it takes for a hard drive to enter standby.
How linux write cache works
Let’s start by explaining what write-back caching is and how it works to better understand the Linux write cache. Write caching is a feature available on most hard drives that allows them to collect all data into the drive’s cache memory, before being permanently written to disk. Once a certain amount of data is collected in the hard drive’s cache memory, the whole data chunk is transferred and stored with a single writing event.
How to check hard drive power on hours in Linux
In this how to check hard drive power on hours in Linux you will see how you might prevent disaster, by knowing details about system’s storage device in terms of “power on” hours (runtime), number of read and writes, or bad blocks, to determine the overall hard drive’s health and ageing.
VirtualBox increase disk size on Linux
In this tutorial you will learn how to increase disk size on VirtualBox. One of the great things about installing an operating system into a virtual machine is that we can easily change the machine’s CPU utilization limit, its memory usage, and the amount of hard drive space it has. With VirtualBox, all of these hardware specifications can even be changed long after the virtual machine is created.
Megatools Linux install and Basic Introduction

wipefs Linux command tutorial with examples
The wipefs Linux command utility can be used to erase various types of signatures from a device (partition tables, filesystem signatures, etc…). It is available in the repository of all the most used Linux distributions, and it is usually installed by default as part of of the util-linux package, which contains also other essentials utilities aimed at system maintenance, so we should never have to install it explicitly. In this tutorial we will see how to use wipefs to gather information about the existing signatures and how to erase them.
