安装lvm2

yum install lvm2

PV、VG创建

方式一：PV建在分区上

lsblk
parted /dev/sdb mklabel msdos
parted /dev/sdc mklabel msdos
parted /dev/sdd mklabel msdos
parted /dev/sde mklabel msdos

parted /dev/sdb mkpart primary 0% 100%
parted /dev/sdc mkpart primary 0% 100%
parted /dev/sdd mkpart primary 0% 100%
parted /dev/sde mkpart primary 0% 100%

pvcreate /dev/sd[bcde]1

vgcreate ofs /dev/sdb1
vgcreate ddup /dev/sdc1
vgcreate self /dev/sdd1
vgcreate meta /dev/sde1

方式二：PV建在硬盘（LUN）上

lsblk
pvcreate /dev/sd[bcde]

vgcreate ofs /dev/sdb
vgcreate ddup /dev/sdc
vgcreate self /dev/sdd
vgcreate meta /dev/sde

创建LV，并格式化

lvcreate -l 100%FREE -n ofs ofs
lvcreate -l 100%FREE -n ddup ddup
lvcreate -l 100%FREE -n self self
lvcreate -l 100%FREE -n meta meta

mkfs.xfs /dev/mapper/ofs-ofs
mkfs.xfs /dev/mapper/ddup-ddup
mkfs.xfs /dev/mapper/self-self
mkfs.xfs /dev/mapper/meta-meta

创建对应目录，并挂载卷

创建挂载点目录

mkdir -p /abvol/{ofs,ddup,self,meta}

在/etc/fstab中添加如下内容：

/dev/mapper/ofs-ofs      /abvol/ofs      xfs    defaults    0 0
/dev/mapper/ddup-ddup    /abvol/ddup     xfs    defaults    0 0
/dev/mapper/self-self    /abvol/self     xfs    defaults    0 0
/dev/mapper/meta-meta    /abvol/meta     xfs    defaults    0 0

挂载并查看卷

mount -a
cat /etc/fstab
df -Th
pvs
vgs
lvs
