What Is LVM Linux?
LVM is also referred to as logical volume manager. It is available for Linux kernel. Its main purpose is to manage disk drives and other mass- storage devices. Though LVM stands for logical volume manager, it can also mean logical volume management. It holds true if it is used with the IBM AIX, HP-UX, or OS/2 operating systems.
Uses of LVM Linux;
- It is perfect for managing hard disks through adding disks or replacing disks. It can also work by means of copying and sharing the contents. This can happen without interrupting the service at all.
- It allows the creations of backups just in case things do not go the right way.
- LVM also makes it possible the resizing of disk partitions as easy as possible. This holds true for smaller systems such as desktops.
- LVM also allows dynamic volume resizing which can be applicable in certain cases. Again, this is only applicable in certain cases.
Capabilities of LVM Linux:
- It resizes volume groups through the absorption of new volumes or the eradication of the existing ones.
- Creates both read- only and read- write snapshots of logical volumes.
- Allows the movement of logical volumes between PV’s online.
- Divide or merge different volume groups.
As you start using it and doing all the above-mentioned processes, you will find out that it is a lot easier than you think it is. Well, this is the beauty in the use of LVM Linux. It allows you to do many things without actually placing that much effort. It will also let you do more as you find out its other capabilities. Though it can be difficult at first, as soon as you do the stuff, you will find it a lot easier. Again, only LVM Linux can make all these come to life.
