AWS - EBS 볼륨 스케일업

EBS 탭에가서 스케일 업할 블럭의 사이즈를 올린다.

변경할 파일 시스템을 확인한다

나는 /dev/nvme1n1p1  루트에 마운트된 파일시스템을 스케일 업 할것이다.

$ df -h

추가된 사이즈를 확인하고

현재 나는 10G를 사용하고 있었고 20G로 스케일 업하였다.

$ lsblk

디바이스 파트를 그로우업 해주고

$ sudo growpart /dev/nvme1n1 1

CHANGED: partition=1 start=2048 old: size=20969439 end=20971487 new: size=41940959,end=41943007

해당 디바이스를 리사이즈 해준다.

$ sudo resize2fs /dev/nvme1n1p1

resize2fs 1.44.1 (24-Mar-2018)
Filesystem at /dev/nvme1n1p1 is mounted on /; on-line resizing required
old_desc_blocks = 2, new_desc_blocks = 3
The filesystem on /dev/nvme1n1p1 is now 5242619 (4k) blocks long.

 

완료!!!
