Proxmox VE（PVE）硬盘扩容，支持EMMC

Posted on by 博主

pve，esxi都是用lvm管理分区，可以使用lvm扩容分区

  • 启动emmc里的pve
  • 扩充的是local-lvm（local主要是VZDump备份文件, ISO镜像, 容器模板，local-lvm主要是 磁盘映像, 容器）
  • 使用putty、xshell一类的软件通过ssh进pve，端口22，用户名root，密码是安装pve时设置的密码

扩容前

检查可能出现的情况

fdisk -l

如果提示

GPT PMBR size mismatch (67108863 != 121634815) will be corrected by write.

执行

apt-get update
apt-get install parted
parted -l

Fix

扩容分区

安装需要的软件

apt-get update
apt-get install parted

执行

fdisk -l

查看系统内硬盘名称（这一步可省略）

lsblk

提示

如果是emmc，硬盘名称是mmcblk1，执行

parted /dev/mmcblk1

如果是非emmc，硬盘名称是sda，执行

parted /dev/sda

提示

扩容LVM，执行

resizepart 3 100%

quit

提示

(parted) resizepart 3 100%
(parted) quit
Information: You may need to update /etc/fstab.

更新物理卷的大小，LVM所在驱动器

如果是emmc，执行

pvresize /dev/mmcblk3

非emmc，执行

pvresize /dev/sda3

提示

Physical volume "/dev/sda3" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized

扩容逻辑卷，执行

cat /etc/pve/storage.cfg

提示

dir: local
        path /var/lib/vz
        content iso,vztmpl,backup

lvmthin: local-lvm
        thinpool data
