无法将启动磁盘获取到200GB [英] Can't get the boot disk to 200GB

问题描述

我尝试先通过gcutil adddisk创建磁盘，然后在运行带有--disk标志的gcutil addinstance时将其分配给VM.但是，即使我在adddisk上将其设置为200GB，该方法仍会导致10GB分区.

I tried creating the disk first via gcutil adddisk and then assigning it to the VM when running gcutil addinstance with the --disk flag. However, this method still results in a 10GB partition even though I set it to 200GB on adddisk.

这是磁盘本身:

但是，如您所见，运行df -h会将其显示为9.9GB:

But, as you can see, running df -h displays it as 9.9GB:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       9.9G  4.3G  5.1G  46% /
tmpfs           7.3G     0  7.3G   0% /dev/shm

我也尝试按照以下说明进行操作: https://developers.google. com/compute/docs/disks#repartitionrootpd

I have also tried to follow these instructions here: https://developers.google.com/compute/docs/disks#repartitionrootpd

但是，重新启动后，虚拟机变得不可访问，因此我什至无法通过SSH重新登录到计算机.

However, on reboot, the VM becomes inaccessible so I can't even SSH back onto the machine.

为什么Google会在启动时强制执行10GB的映像?为什么未将其设置为我要求的尺寸?更重要的是，有没有办法使我们的构建脚本自动化此过程?

Why is Google enforcing a 10GB image on boot? Why is it not being set to the size I have requested? More importantly, is there a way I can automate this process for our build scripts?

推荐答案

一种选择是使用永久磁盘快照:

• 调整磁盘大小
• 创建磁盘快照
• 在构建脚本中，从快照而不是默认映像中创建新的PD

新磁盘将为200GB.快照仅保存已更改的块，因此快照本身应很小.

The new disks will be 200GB. Snapshots only save blocks which have changed, so the snapshot itself should be fairly small.
