Extend root volume (AWS Dashboard)

  • Check the box for the instance you want to extend
  • Click on the storage tab below and find the volumes
  • Click on the volume hyperlink and select the checkbox
  • Select modify and add the additional storage desired

Steps to extend the Root Volume (AWS CONSOLE)

Ensure you have extended the volume within the AWS EBS dashboard to be larger than the default 32 GiB.

  • Check the allocation and available disk space
    • df -hT
  • Checks how much disk space is available, mount points, and type of storage device
    • lsblk
  • Check the size of the root volume group
    • sudo vgs
  • Grow the partition that is housing the volume group from the newly added storage
    • sudo growpart /dev/xvda 2 *To check that the storage has been increased
    • lsblk
    • Should look similar to this:
NAME                MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
xvda                202:0    0  100G  0 disk
├─xvda1             202:1    0    8G  0 part /
└─xvda2             202:2    0   28G  0 part
  ├─rootvg-tmp      253:0    0    5G  0 lvm  /var/tmp
  ├─rootvg-var      253:1    0    5G  0 lvm  /var
  ├─rootvg-varlog   253:2    0    5G  0 lvm  /var/log
  ├─rootvg-varaudit 253:3    0   10G  0 lvm  /var/log/audit
  └─rootvg-home     253:4    0    1G  0 lvm  /home
  • Resize the volume specific in the /dev directory
    • sudo pvresize /dev/sda2
  • Confirm a size increase for the root volume
    • sudo pvs
  • Allocates ALL the available free space to the root volume
    • IF you only want a certain amount allocated then use -L #GB /path
    • sudo lvextend -l +100%FREE /dev/rootvg/var
  • Extend the root volume with the allocated free space
    • sudo xfs_growfs /dev/rootvg/var
