While a copy is being made, any new information that needs to be added to the logical volume is written to the disk just like normal, but changes are tracked so that the original picture never gets destroyed. Linux Logical Volume Manager (LVM) is a common general-purpose storage manager in all popular Linux distributions.

When LVM takes a snapshot, a picture is taken of exactly how the logical volume looks and that picture can be used to make a copy on a different hard drive. One of the coolest things about LVM snapshots is your file system is never taken offline and you can have as many as you want without taking up extra hard drive space.

Backing up a Logical Volume LVM (Logical Volume Manager) for the Linux Kernel is a method of allocating hard drive space into logical volumes, this also allows for the easy creation. The presented work includes proposal of the mathematical modeling of file. remove hard drive from volume group with vgreduce This paper presents a performance evaluation of LVM (Logical Volume Manager) system under the Linux operating system.reduce logical volume (instead of + to extend you can also use – to reduce by size).resize file system (make sure to move files to a safe area of the hard drive before resizing). ![]() If you wanted to remove a hard drive from a volume group you would need to follow the above steps in reverse order and use lvreduce and vgreduce instead. ![]()
