pvcreate /dev/nvme0n1 --config global{metadata_read_only=0} 使用pvcreate转换

pvdisplay 查看已经存在的pv

vgcreate nvme0n1VG /dev/nvme0n1 --config global{metadata_read_only=0} 创建VG，可利用已经存在的VG名（myVG），同一VG名下的一组PV构成一个VG

vgdisplay 查看VG 创建完成VG之后，才能从VG中划分一个LV

lvcreate -l 100%FREE -n nvme0n1LV nvme0n1VG --config global{metadata_read_only=0} 创建LV，并把VG所有剩余空间分给LV

lvdisplay 显示LV的信息

mkfs.ext4 /dev/nvme0n1VG/nvme0n1LV 对LV进行格式化（使用mksf进行格式化操作），然后LV才能存储资料
