Extending Existing Logical volume:

Steps:

1) Identify partitions

2) Identify Volume Group

3) Extend Volume Group

4) Extend Logical Volume


Identify partitions:

identify and format disk to LVM partition 8e once created create a PV as below

#pvcreate /dev/sdd (10G)


Identify Volume Group:

list volume groups  available on the machine using vgs

# vgs

  VG   #PV #LV #SN Attr   VSize   VFree

  vgname   1   5   0 wz--n- 299.04g    0


Extend Volume Group:

#vgextend vgname /dev/sdd

# vgs

  VG   #PV #LV #SN Attr   VSize   VFree

  vgname   1   5   0 wz--n- 309.04g    0


Extend Logical Volume:

#lvextend -l +100%FREE /dev/vgname/lvname (Adds maximum available free space to the Logical Voulme)

or

#lvextend -l +10G /dev/vgname/lvname ( Increase Logical Volume by 10G )


#resize2fs /dev/vgname/lvname

Terraform Basics

-
✅ Provider: A provider is a plugin for Terraform that defines and manages resources for a specific cloud or infrastructure platform. Examples of providers include AWS, Azure, Google Cloud, and many others. You configure providers in your Terraform code to interact with the desired infrastructure platform. ✅ Resource: A resource is a specific infrastructure component that you want to create and manage using Terraform. Resources can include virtual machines, databases, storage buckets, network components, and more. Each resource has a type and configuration parameters that you define in your Terraform code. ✅ Module: A module is a reusable and encapsulated unit of Terraform code. Modules allow you to package infrastructure configurations, making it easier to maintain, share, and reuse them across different parts of your infrastructure. Modules can be your own creations or come from the Terraform Registry, which hosts community-contributed modules. ✅ Configuration File: Terraform uses con...
