What is the use of LVM in Linux disk management?

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.

What is LVM and when why would you use it?

LVM, or the Logical Volume Manager, is a Linux volume partitioning solution that has been around for some time and provides a number of advanced features. LVM provides more flexibility when compared with traditional partitions, which can be extremely useful in many cases.

What is LVM explain?

Logical volume management (LVM) is a form of storage virtualization that offers system administrators a more flexible approach to managing disk storage space than traditional partitioning. This type of virtualization tool is located within the device-driver stack on the operating system.

How would you create a logical volume LVM and mount the file system?

How to create a LVM in Linux, these are the below steps to be followed.

1. Select or Identify the correct disks to be used for LVM.
2. Create a Physical Volumes(PV) on the disk.
3. Create the Volume Group(VG) on the Physical Volumes.
4. Create Logical Volumes(LV) on the Volume Group.
5. Create a filesystem for the logical volumes.

What is the main advantage of using Logical Volume Management LVM on a Linux system?

The main advantages of LVM are increased abstraction, flexibility, and control. Logical volumes can have meaningful names like “databases” or “root-backup”. Volumes can be resized dynamically as space requirements change and migrated between physical devices within the pool on a running system or exported easily.

What is the logical order for creation of an LVM logical volume?

In order to create LVM logical volumes, here is a basic four step procedure: Create partitions to be used and initialize them as physical volumes. Create a volume group. Create a logical volume.

How do you mount a logical volume?

The procedure to mount LVM partition in Linux as follows:

1. Run vgscan command scans all supported LVM block devices in the system for VGs.
2. Execute vgchange command to activate volume.
3. Type lvs command to get information about logical volumes.
4. Create a mount point using the mkdir command.
