How to increase volume without downtime

1. Take a snapshot of your volume - wait 5 min
2. open the main volume, click modify and increase the size from e.g. 30 GB to e.g. 40 GB
3. Exted OS filesystem

• SSH into you instance.
• Type df -h to check volume size; You will still have 30GB of volume size.
• Type lsblk Your increased volume will be shown just above your current volume, e.g. xvda1 is your current volume with 30GB size and xvda with 40GB size.
• Extend the partition by typing sudo growpart /dev/xvda 1 ; Note that dev/xvda is the partition name and 1 is the partition number.
• Extend the volume by typing sudo xfs_growfs /dev/xvda1 or sudo resize2fs /dev/xvda1 If you see error try the other one.
