[Resolved] Amazon EC2 Redhat 7 using 6GB for the root space

I create new server with 10GB of HDD, but when i check on the command line, the root space only show 6GB. I'm using t2.micto and Redhat 7.0, disk type: XFS.

- xvda1: boot partition

- xvda2: root partition

Fix Step:

We have instance A with the volume VA.

1) Stop the current instace A

2) Snapshot the current volume VA of the instance A

3) Start the instance A

4) Create new volume with 25GB by using the snapshot of volume VA then we have new volume VB

5) Attach the new volume VB to the instance A as default (/dev/sdf)

6) From the ssh console, i use the lsblk command to list the disk.

# lsblk

7) Using the xfs_repair to repair the /dev/xvdf2
( yum install xfsprogs)

# xfs_repair /dev/xvdf2

8) Continue as the image below

9) Remove the /dev/xvdf2, remember the start of this disk then we will create the new one with the same.

10) Using XFS command to repair the /dev/xvdf2 again.
# xfs_repair /dev/xvdf2
11) Use the lsblk command to test the disk space again.

12) Stop the instance A again

13) Deattach the volume VA from the instace A

14) Attach the volume VB to the instance A (/dev/sda1)

15) Start the instance then using the command to check the root space.

# df -lTh

# lsblk
