LVM (Logical Volume Manager)逻辑卷管理是在Linux2.4内核以上实现的磁盘管理技术。 它是 Linux环境下对磁盘分区进行管理的一种机制。 现在不仅仅是Linux系统上可以使用LVM这种磁盘管理机制，对于其它的类UNIX操作系统，以及windows操作系统都有类似与LVM这种磁盘管理软件。 物理卷，将实际的磁盘分区（partition）系统识别码（system ID）修改为8e后，在通过 pvcreate 指令转化为LVM最底层的 物理卷，作为后续空间管理的基础。 卷组，将数个PV进行整合，即 …

2021年12月12日 · LVM（Logical Volume Manager，逻辑卷管理器）是 Linux 系统中对磁盘分区进行管理的一种逻辑机制，它允许动态调整磁盘容量，提高磁盘分区管理的灵活性。LVM 提供了方便调整逻辑卷大小的能力，可以方便地对卷组、逻辑卷的大小进行调整，更进一步调整文件系统的 ...

2025年1月2日 · LVM stands for Logical Volume Manager. A mechanism that provides an alternative method of managing storage systems than the traditional partition-based one. In LVM, instead of creating partitions, you create logical volumes, and then you can just as easily mount those volumes in your filesystem as you'd a disk partition.

2024年12月9日 · LVM是Logical Volume Manager (逻辑卷管理)的简写，它是Linux环境下对磁盘分区进行管理的一种机制。 它由Heinz Mauelshagen在Linux 2.4 内核上实现，最新版本为：稳定版 1.0.5，开发版 1.1.0-rc2，以及LVM2开发版。 我们学习的Ceph底层就用到了LVM技术栈。 指系统的物理存储设备：磁盘(/dev/hda，/dev/sda)或者分区(/dev/sdb1，/dev/sdb2)等，是存储系统最底层的存储单元。 指磁盘分区或从逻辑上与磁盘分区具有同样功能的设备(如RAID)，是LVM的 …

2010年9月4日 · With LVM you can group the hardrives into one huge one. Also you can add more space to this group if you add more harddrives. With LVM you can simple work like you have only one single huge harddrive. Despite that LVM supports a lot expert features.

LVM is used for the following purposes: Creating single logical volumes of multiple physical volumes or entire hard disks (somewhat similar to RAID 0, but more similar to JBOD), allowing for dynamic volume resizing.

LVM is a tool for logical volume management which includes allocating disks, striping, mirroring and resizing logical volumes. With LVM, a hard drive or set of hard drives is allocated to one or more physical volumes. LVM physical volumes can be placed on other block devices which might span two or more disks. Physical volumes (PV)

Logical Volume Manager (LVM) is a device mapper framework that provides logical volume management for the Linux kernel. Logical Volume Management utilizes the kernel's device-mapper feature to provide a system of partitions independent of underlying disk layout.

2021年4月10日 · 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. In this guide, you’ll learn how LVM works on Linux systems .

2023年8月21日 · LVM revolutionizes how disk partitions and physical storage are managed, providing an abstract layer that simplifies storage administration and facilitates efficient utilization of available resources.
