扩展已有磁盘的容量

以扩展磁盘 /dev/sda 为例，

sudo dd iflag=direct if=/dev/sda of=/dev/null count=1
echo "1" | sudo tee /sys/class/block/sda/device/rescan
echo "y" | sudo /usr/libexec/oci-growfs

挂载新加磁盘

已挂载 /dev/sdb 为例，

sudo lsblk

sudo parted -s -a optimal /dev/sdb \\mklabel gpt \\mkpart primary 0% 100% \\set 1 lvm on

sudo parted /dev/sdb print

sudo pvcreate /dev/sdb1

sudo vgcreate vg01 /dev/sdb1

sudo lvcreate -l 100%FREE -n lv_data vg01

sudo mkdir /mnt/sdb
sudo chown opc:opc /mnt/sdb/

lsblk -o +UUID

sudo vi /etc/fstab--- add
UUID=<lv_data's UUID> /mnt/sdb xfs defaults,_netdev,nofail 0 2
---

sudo mount -a

df -h

完结！
