How to Extend/Reduce LVM’s (Logical Volume Management) in Linux 小小工匠 2021/08/16 5150 LVM详解 其他 petmaster出品必是精品 一、概述 LVM全称为Logical Volume Manager,即逻辑卷管理器。LVM可以弹性的调整文件系统的容量,可以将多个物理分区整合在一起,并且根据需要划分空间或动态的修改文件系统空间。 LVM有...
Previously we have seen how to create a flexible disk storage using LVM. Here, we are going to see how to extend volume group, extend and reduce a logical volume. Here we can reduce or extend the partitions in Logical volume management (LVM) also called as flexible volume file-system. Ex...
Linux offers three native tools for disk partitioning:fdisk,gdisk, andparted. Thefdiskcreates only MBR partitions. Thegdiskmakes only GPT partitions. Thepartedcreates both partition types. We can use any one of these to create LVM partitions. We will use thefdiskandpartedto create LVM partitions ...
逻辑卷管理LVM是一个多才多艺的硬盘系统工具。无论在Linux或者其他类似的系统,都是非常的好用。传统分区使用固定大小分区,重新调整大小十分麻烦。但是,LVM可以创建和管理“逻辑”卷,而不是直接使用物理硬盘。可以让管理员弹性的管理逻辑卷的扩大缩小,操作简单,而不损坏已存储的数据。可以随意将新的硬盘添加到LVM,以...

Compression allows you to reduce the size of a file. By decreasing use of theinodestable, it means more files and folders can be stored, maximizing the space available on physical storage. In Linux, system administrators have used tools such as zip, tar, gzip, bzip2, and other open source...
this space is LVM caching, which significantly enhances performance by leveraging fasterstorage devices, like solid-state drives (SSDs), to cache data from slower ones. This strategy is particularly beneficial in scenarios involving frequent read operations, as it can substantially reduce access times...
, orLVM, is a storage device management technology that gives users the power to pool and abstract the physical layout of component storage devices for flexible administration. Using thedevice mapperLinux kernel framework, the current iteration, LVM2, can be used to gather existing storage dev...
