what is Disk Partitions? - Partitions in Windows?

Disk Partitions 

LVM stands for Logical Volume Manager. Logical Volume Manager allows for a level of abstraction between your operating system and the disks\/partitions it uses. It's a system of controlling your stresses logical volumes, or file systems. With LVM, partitions and disks can be abstracted to contain many disks and walls to one device. Hmmmm. Looks exciting. Now let me should I utilize LVMTell me some benefits of using LVM. Most surgeries can be performed on the fly, whilst the system is running. LVM can enlarge a partition while it's mounted, even if the file system used on in addition, it supports that.

LVM can move a partition while it's in use, and won't corrupt your data if it's interrupted. It allows to take snapshots at any moment, although the system is running. Well, you forced me to think. So how LVM differs from traditional disk management? Traditional Disk Management - OS looks for what disks are available. Then looks at what walls are available on these discs. LVM Disk Control - A physical disk is split into more than one physical volumes. Physical Volumes corresponds to physical disk walls. Logical volume groups are created by mixing Physical Volumes. A logical volume group is a group of physical volumes where a logical volume can be created. 


                                  

Logical volumes correspond to partitions plus they hold a file system. A reasonable volume lives in a volume group that's composed of more than one physical volumes. Ooppssss. That was too much specialized for me, but how I could manage LVM? You will find adequate commands to handle LVM. Every LVM control is preceded by one of these: Physical Volume = pv - Volume Team = vg - Realistic Volume = lv - For LVM info you could utilize - The command: Things are going over my mind. Show me some practical stuffs. Please do some LVM stuffs to get me.

And you've to do it for me. Add 3 New discs to my Linux machine. Create partitions on these 3 disks. So for this blog post. We can see the three added disks in the below screen shot: Partitioning 1st disk - We will create two primary partitions on the 1st disk \/dev\/sdb. T = Change partition type - 8e = Hexa decimal code to get Linux LVM - Creation 2nd Partition of remaining space on disk \/dev\/sdb. Partitioning 2nd disk - We will create only a single primary partition on the 2nd disk \/dev\/sdc. Partitioning is time intensive. I'm tired. Show me something.
