What are the biggest advantages of using LVM over traditional disk partitioning?
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.

Does LVM affect performance?
The tests seem to suggest the performance drop can be from 15% to 45% with LVM, compared to when not using it. They found an even bigger drop when two physical partitions are used within one LVM setup. They concluded that the biggest performance impacts were the use of LVM, as well as the complexity of it’s use.
What is LVM and when why would you use it?
You can think of LVM as “dynamic partitions”, meaning that you can create/resize/delete LVM “partitions” (they’re called “Logical Volumes” in LVM-speak) from the command line while your Linux system is running: no need to reboot the system to make the kernel aware of the newly-created or resized partitions.
How do I extend my logical volume?

Is it possible to increase the logical volume on fly?

Why does my 4TB hard drive only show 2TB?
Why does 4TB hard drive only shows 2TB? The answer is the partition table of the 4TB hard drive is MBR, which supports only up to 2 TB data density. The partitions were organized using a scheme called the Master Boot Record (MBR) which is the most widely used partition scheme in personal computers.
How increase LVM size in Linux?
Extend LVM manually
- Extend the physical drive partition: sudo fdisk /dev/vda – Enter the fdisk tool to modify /dev/vda.
- Modify (extend) the LVM: Tell LVM the physical partition size has changed: sudo pvresize /dev/vda1.
- Resize the file system: sudo resize2fs /dev/COMPbase-vg/root.
How do I mount a lv01 file system in Linux?
Create a directory ‘/media/$USER/lv01’. Mount the filesystem on this directory using the mount command. Now the /dev/vg01/lv01 filesystem can be accessed from the ‘/media/$USER/lv01’ directory, and data can be stored on this location.
What happens if a Disk Utility is unfamiliar with LVM?
Most importantly, a disk utility that’s unfamiliar with LVM could misbehave when it sees a “raw” PV instead of a partition table. This could have unknown consequences in the future. Show activity on this post.
