=====Using LVM=====

LVM is Linux's Volume Management. It is a default during installation

====Creating a new LVM====

This is done in 3 main steps
  
  - Create a new partition on a disk and marking as type 8e then run 
  pvcreate /dev/sdX#
  
  - Create a new Volume group set run **vgcreate **


====Extend a LVM====

To extend a lvm you need to extend the volume group this is done by adding a new partition to it.
Once you have the partition created run

  lvextend -l +100%FREE -r  /dev/volume-group-name/logical-volume-name
  
found another interesting way to extend a disk.

If you have added a whole new partition that you want to use to extend a partition you can just vdo

  lvextend -r /dev/volume-group-name/logical-volume-name /dev/sdX
  
The **-r** option is to run a resize2fs on the exntension.If you do not use it you need to run

  resize2fs /dev/volume-group-name/logical-volume-name
