在Google云端平台上创建实例时，如何增加默认的10GB启动驱动器？我已经阅读了关于此的不同答案，没有什么超级明确的。我是平台的初学者，如果有人能用简单的话告诉我如何做到这一点，我真的很感激。

使用以下步骤通过Google Cloud Platform上的CentOS增加启动大小。
ssh into vm instance
[user@user-srv ~]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.9G 898M 8.5G 10% /
tmpfs 296M 0 296M 0% /dev/shm
[user@user-srv ~]$ sudo fdisk /dev/sda
The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

不重新启动或重新启动会增加GCP云VM或Google云引擎中的启动大小
如果危险超过80％，请检查第一个磁盘使用率是否超过/dev/sda1的{{1}}的80％。
无需重新启动即可即时更新VM的磁盘大小
sudo growpart /dev/sda 1 sudo resize2fs /dev/sda1 df -h 答案 3 :(得分：0)
比直接编辑分区更安全的方法并且不需要维护自己的图像，是dracut的growroot模块＆amp;云初始化
我在CentOS 6＆amp; 7 Google Compute，AWS＆amp;天青。
## you'll need to be root or use sudo
yum -y install epel-release
yum -y install cloud-init cloud-initramfs-tools dracut-modules-growroot cloud-utils-growpart
rpm -qa kernel | sed -e 's/^kernel-//' | xargs -I {} dracut -f /boot/initramfs-{}.img {}
# reboot for the resize to take affect
分区将在下次启动时自动调整大小。
注意：
