Logical Volume Management(LVM) is a powerful tool that greatly simplifies disk space management. WithLVM, the task of allocating additional space to a file system becomes effortless. Whenever a file system requires more space, it can easily draw from the available free space in its corresponding ...
How to Take ‘Snapshot of Logical Volume and Restore’ in LVM 概述 在Linux中扩展/缩减LVM 前面我们已经了解了怎样使用LVM创建弹性的磁盘存储。这里,我们将了解怎样来扩展卷组,扩展和缩减逻辑卷。在这里,我们可以缩减或者扩展逻辑卷管理(LVM)中的分区,LVM也可称之为弹性卷文件系统。 什么时候我们需要缩减卷?
Compression allows you to reduce the size of a file. By decreasing use of the inodes table, it means more files and folders can be stored, maximizing the spa...
Let’s start by defining abad sector/bad block, it is a section on a disk drive or flash memory that can no longer be read from or written to, which usually happens due topermanent physical damage on the disksurface or failing flash memory transistors. As more bad sectors build up, the...
You could install the many lighter Raspberry Pi distros (Raspberry Pi OS Lite, or Diet Pi for example). But what if we want to reduce our running installation? Linux uses package managers to install and remove software packages. Software is downloaded from official (or third party) repositories...
However, if you want to check disk usage for directories and files, you are going to use the “du” command. Check Disk Space on Linux using du The du command stands for “disk usage” and it is used in order to have disk usage information related to directories and files on your sys...
