linux lvm

Linux has been operating the company's FTP server for LVM for several years. Now there is a shortage of space, and it is decided to use LVM for resizing. Idea: first copy the data, purchase a large-capacity hard disk and add it to the server, and then convert the existing common partition into a physical volume, finally, you can use physical volumes to create log

The most common hard-to-decide problem that Linux users encounter when installing the Linux operating system is how to correctly evaluate the size of each partition to allocate suitable hard disk space. When a partition space is exhausted, the solution is usually to use a symbolic link or a tool to adjust the partition size (such as PatitionMagic), but this is only a temporary solution, the problem is not f

Linux LVM simple tutorial Logical volume management LVM is a versatile hard disk system tool. Both Linux and other similar systems are very easy to use. It is very troublesome to adjust the size of a traditional partition by using a fixed size partition. However, LVM can cre

Summary: One of the most common and difficult decisions that Linux users encounter when installing a Linux operating system is how to properly assess the size of each partition to allocate appropriate hard disk space. When a partition space is exhausted, the solution is usually to use symbolic links, or tools that resize the partition (such as Patition magic, etc.), but this is a temporary solution and does

through the most learning, I deepened the understanding of LVM, here, I write it blog, one is to facilitate their own memory, and the second is to let the Linux beginners learn together. First we introduce the concept of LVM, and expand the detailed description, mainly the recent study of the view, we first look at a figure650) this.width=650; "src=" http://s3.51

) on a volume group, and an LVM volume group consists of one or more physical volumes. Logical volumes (logical volume): LVM logical volumes are similar to hard disk partitions in non-LVM systems, and file systems (such as/home or/usr) can be created on top of logical volumes. PE (physical extent): each physical volume is divided into a basic unit called PE (

Remember!0x00: Preface.In the Linux use process, found a file is very large, such as 5G, but there are two physical disk one Left 4 G, one left 3G, disk space is not enough, so certainly can't put in. If the 5G file is divided, it can be put in, but if there are many f

First, the basic concept of LVM When you partition a disk to a size plan, sometimes can not determine the total size of the partition to use, and with Fdisk after the partition of the disk, each partition size has been fixed, if the partition set too large, wasted disk space, and the partition set too small, will lead to insufficient space to use the situation, The most common method at this point is to repartition the partition, or link the partitio

LVM BasicsBy using the logical Volume Manager of Linux (Logical Volume Manager, LVM), users can dynamically resize the file system while the system is running, relocate data from one hard drive to another, improve the performance of I/O operations, and provide redundant protection Its snapshot feature allows users to make real-time backups of logical volumes.For

The LVM is shorthand for Logical Volume Manager (Logical Volume management), a mechanism for managing disk partitions in a Linux environment that is implemented by Heinz Mauelshagen on the Linux 2.4 kernel. The latest version is: Stable version 1.0.5, development version 1.1.0-rc2, and LVM2 development version. A common and difficult problem that

Before configuring logical volume management and configuration, we think about a problem. we all know that Linux is a multi-user mode. when our preliminary plan causes insufficient hard disk space, in general, we add a new hard disk, partition and format the disk, copy the data of the disk that is not properly planned, and then re-mount the disk to take effect. If we Logical Volume management and configuration Before configuration, we want to have a p
