Rocky Linux 9 : LVM 구현

 

실습 목표

1. 디스크 파티셔닝

fdisk /dev/sda

n -> 디폴트 1 -> 디폴트 2048 -> 디폴트 사이즈 -> 타입 t -> linux LVM 8e -> 확인 p -> 저장 w

 

2. PV -> VG -> LV -> File System 

pvcreate /dev/sda1

pvscan

vgcreate jyjang /dev/sda1

vgdisplay

lvcreate -L 1G -n jyjang1 jyjang
mkfs.xfs /dev/jyjang/jyjang1

lvcreate -L 2G -n jyjang2 jyjang
mkfs.ext4 /dev/jyjang/jyjang2

lvcreate -l (vgdisplay에서 확인한 남는 용량) -n jyjang3 jyjang
mkfs.ext3 /dev/jyjang/jyjang3

lvscan

 

 

3. Mount , 확인

mkdir /lv{1,2,3}

mount /dev/jyjang/jyjang1 /lv1
mount /dev/jyjang/jyjang2 /lv2
mount /dev/jyjang/jyjang3 /lv3

lsblk
df -Th

 

 

 

4. sdc 디스크를 이용해서 모든 LV의 용량을 1G씩 업그레이드

 

fdisk /dev/sdc

n -> 디폴트 -> t -> 8e -> p -> w

 

pvcreate /dev/sdc1

vgextend jyjang /dev/sdc1

lvextend -L +1G /dev/jyjang/jyjang1
lvextend -L +1G /dev/jyjang/jyjang2
lvextend -l  +1G /dev/jyjang/jyjang3

 

 

xfs_growfs  /dev/jyjang/jyjang1

resize2fs /dev/jyjang/jyjang2

resize2fs /dev/jyjang/jyjang3

df -Th
lsblk

 

 

5. 초기화

umount /lv1 /lv2 /lv3

wipefs -a -f /dev/jyjang/jyjang{1,2,3}

lvremove /dev/jyjang/jyjang{1,2,3}

vgremove jyjang

pvremove /dev/sdc1 /dev/sda1

fdisk /dev/sda
