How to Extend a LVM on Ubuntu

-

 ok so here is how to extend a LVM volume on a ubuntu server/desktop machine ( this was done on a virtual machine)

  1. open the guest in vmware and increase the volume size
  2. ssh into the guest
  3. type fdisk /dev/sda (if you have a diffrent disk you will need to use the appropriate disk name)
  4. press p (to display the partition table)
  5. create a new partiton the same type as the last partition (press n)
  6. keep pressing enter until you get to the partition type and set it the same as the last one
  7. leave the rest as default, keep pressing enter
  8. press w (to write to the partition table)
  9. restart the machine
  10. type vgdisplay (make note of the name of your volume group)
  11. type vgextend ubuntu-vg /dev/sda3 (replace ubuntu-vg with the name of the volume group and 3 with the new partition number u just created)
  12. extend the lvm by typing lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv /dev/sda4 (make sure the lvm name is correct and sda4 is the new partition
  13. extend the volume by typing resize2fs /dev/ubuntu-vg/ubuntu-lv
  14. type df -h and confirm the new volume size

Msg . alert ( gettext ( 'Error' ), response. htmlStatus ); }, success : function ( response, o...

 so i have found this app recently and thought i would share. XPipe is a new type of shell connection hub and remote file manager that allows you to access your entire server infrastructure from your local machine. It works on top of your installed command-line programs and does not require any setup on your remote systems. XPipe fully integrates with your tools such as your favourite text/code editors, terminals, shells, command-line tools and more. The platform is designed to be extensible, allowing anyone to add easily support for more tools or to implement custom functionality through a modular extension system. i have only had a quick look at it but seems like an awesome app so far. check it out here
