xfs 로 디스크 생성하기

대세에 따라. xfs 를 사용하기로 함. 안녕 ext4 ㅠㅠ (xfs 를 제외한 나머지는 기존내용 복붙)

 

 

디스크 추가 

 

## insert disk

 

 

 

fdisk /dev/vdb

n

p

1

[enter]

[enter]

w

mkfs.xfs /dev/vdb1

mkdir /data

mount /dev/vdb1 /data

echo "/dev/vdb1               /data                   xfs    defaults,nofail        0    0">>/etc/fstab

 

## insert disk (AWS 에서 NVME disk 를 사용하는듯. 그에 맞게 변형.

 

 

 

fdisk /dev/nvme1n1

n

p

1

[enter]

[enter]

w

mkfs.xfs /dev/nvme1n1p1

mkdir /data

mount /dev/nvme1n1p1 /data

echo "/dev/nvme1n1p1            /data                   xfs    defaults,nofail        0    0">>/etc/fstab

 

 

 

##확인

 

lsblk

 

NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT

xvda    202:0    0    8G  0 disk

└─xvda1 202:1    0    8G  0 part /

xvdf    202:80   0  500G  0 disk

 

└─xvdf1 202:81   0  500G  0 part /data

 

 

확장 방법은 동일하다. 여기서 xfs_growfs -d 옵션을 쓰는 이유는 디스크 할당양 최대용량을 할당하라는 의미.

xfs_growfs -d /home

##ROOT DISK

growpart /dev/nvme0n1 4
