centos7磁盘新增逻辑卷

磁盘为2T，需要新增一个500G的逻辑卷

查看vgname

vgdisplay
得到vgname  VolGroup01

创建逻辑卷

lvcreate -L 500G -n lvk8slog VolGroup01

格式化逻辑卷

mkfs.xfs /dev/VolGroup01/lvk8slog

挂载目录

mkdir /k8slog
mount /dev/VolGroup01/lvk8slog /k8slog

写入配置，永久生效

vi /etc/fstab
/dev/VolGroup01/lvk8slog /k8slog xfs defaults 0 0

验证

mount -a
lsblk
