以下操作都在下面的虚机目录下进行： /var/lib/libvirt/images/vm-gitlab6/ubuntu-kvm/ 安装必备 $ sudo apt-get install libguestfs-tools 备份文件 $ sudo virsh shutdown vm-gitlab6 $ sudo cp /var/lib/libvirt/images/vm-gitlab6/ubuntu-kvm/vm-gitlab6-img1.qcow2 /var/lib/libvirt/images/vm-gitlab6/ubuntu-kvm/vm-gitlab6-img1-back.qcow2 查看虚机分区大小 $ sudo virt-df -h vm-gitlab6-img1.qcow2 W: kvm binary is deprecated, please use qemu-system-x86_64 instead Filesystem Size Used Available Use% vm-gitlab6-img1.qcow2:/dev/sda1 18G 1.1G 16G 6% 创建新的镜像文件 vm-gitlab6-img1-big.qcow2，给40G大小（瞬间结束，让人以为错误） $ sudo qemu-img create -f qcow2 vm-gitlab6-img1-big.qcow2 40G 下面就是关键的虚拟机扩容 $ sudo virt-resize --expand /dev/sda1 vm-gitlab6-img1.qcow2 vm-gitlab6-img1-big.qcow2 转载请保留固定链接： https://linuxeye.com/Linux/2678.html |
