Master LVM in Linux – Storage Management Like a Pro

By Manish saini

 



• Storage Type 

 1. Floppy disk 

 2. CD/DVD

 3. Pendrive/Memory card

 4. Harddisk--> IDE,SATA,SSD,Nvme


 Disk Partitioning

→ Disk partitioning allows system administrators a hard drive into multiple logical stroge units, referred to as a partitions. 

 → The process to dividing a disk into logical areas that can be worked with separately id called partitioning. 


❖ Types of Partition Scheme 

 1. MBR

 2. GPT


LVM:- Logical Volume Manager 

LVM (Logical Volume Manager) is a Linux feature that allows flexible disk management. It lets you combine multiple disks into a storage pool, create logical partitions, and resize them dynamically without downtime  


• PV:- Physical Volume

In LVM (Logical Volume Manager), a Physical Volume (PV) is simply a storage device (like a hard disk, SSD, or a partition) that is prepared for use in LVM.

• Before using a disk in LVM, you must convert it into a PV using the pvcreate command. 

 • PVs are then combined together to form a Volume Group (VG).


• VG:- Volume Group 

In LVM (Logical Volume Manager), a Volume Group (VG) is a storage pool created by combining one or more Physical Volumes (PVs).

• Think of it like a container of storage. 

 • From this container, you can create Logical Volumes (LVs).

  VPC:-   A VPC (Virtual Private Cloud) in AWS is a private, isolated network you create in the AWS cloud to launch and manage your resources like EC2 instances, databases, etc.  Think of it as your own private data center inside AWS, where you have full control over:   • IP address ranges (CIDR blocks)  • Subnets (public & private)   • Routing (via route tables)  • Internet access (via Internet Gateway or NAT Gateway)   • Security (via security groups & network ACLs) Example    • Suppose you rent a building (AWS Cloud).   • Inside it, you design your own office layout (VPC).   • You decide rooms (subnets), doors (gateways), and locks (security groups). Key Features of VPC    1. Isolated Environment – Your VPC is separated from other AWS users’ networks.  2. Customizable IP Range – You choose IPv4/IPv6 address range.  3. Multiple Subnets – Create public and private subnets. ...
