也可以缩减容量

  1. 查看当前容量


> lvdisplay /dev/pve/root

  LV Name                root

  1. 缩小逻辑卷的大小。假设你想减少10G：

lvreduce -L -10G /dev/pve/root

  1. 检查逻辑卷的缩减前后大小，确保没有错误：

e2fsck -f /dev/pve/root

  1. 调整文件系统大小：

对于ext4文件系统：

resize2fs /dev/pve/root

写入UUID 到 fstab

> echo "848a2e0a-7066-4f3e-8afb-3c6c73ce1717 /mnt/2TData ext4 defaults 0 0" >> /etc/fstab

重新挂载

> mount -a
