Resizing an Amazon EBS Volume

Adjusting Amazon EBS volume size

1. EBS Volume Size Adjustment

: In the AWS Console, modify the volume of the corresponding disk to the required size

2. Linux File System Expansion

• After increasing the EBS volume size, you need to expand the size of the Linux file system

• You can start adjusting the file system size when the volume status becomes optimizing in the AWS console

2-1. Connect to the Instance and Check the File System

[root@scouter ~]# df -alh 
Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme1n1     20G   20G  880M  96% /home/appuser/scouter
binfmt_misc        0     0     0    - /proc/sys/fs/binfmt_misc

• df -alh

  • df

    • disk free command

  • -alh

    • -a

      • all

    • -l

      • local

    • -h

      • human-readable

2-2. Use the xfs_growfs Command to Expand the File System on the Volume

[root@scouter ~]# xfs_growfs /dev/nvme1n1

• This is the command to expand the volume of the /dev/nvme1n1 partition

2-3. Check the File System Size Again

[root@scouter ~]# df -alh
Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme1n1     30G   20G   11G  64% /home/appuser/scouter
binfmt_misc        0     0     0    - /proc/sys/fs/binfmt_misc

• You can confirm that the expanded volume size is reflected in the file system at 30G

Done!
