EBS Volumes Increase Of Running Instance

ebs_volumes.txt

Step:1  increase the volume size from Console.

Step:2  SSH your instance

Step:3 Verify filesystem using df -h command

Step:4 To check whether the volume has a partition that must be extended, use the lsblk command to display information about the block devices attached to your instance.


Step:5 For volumes that have a partition use the growpart /dev/xvda 1 command to extend the partition. Notice that there is a space between the device name and the partition number.     

Step:6 To verify that the partition reflects the increased volume size, use the lsblk command again.

Step:7 To verify the size of the file system for each volume, use the df -h command. In this example output, both file systems reflect the original volume size.

Step:8 To extend the file system on each volume, use the correct command for your file system, as follows:

        [XFS file system] To extend the file system on each volume, use the xfs_growfs -d / command 
        
If the XFS tools are not already installed, you can install them as follows.

                yum install xfsprogs

[ext4 file system] To extend the file system on each volume, use the resize2fs command.

                    resize2fs /dev/volumename
                   
Step:9 Again run df -h command to verify filesystem
