I created a CentOS 7 VM instance through Compute Engine -> VM instances, and it came with xfs by default. I see from this page that Google Cloud supports ext4, but I don't see any option to specify it when creating a VM instance. Is it possible to do so?

  • @Asdfg - Your link does not provide information on how to create a boot disk with ext4. Google Compute Engine images are "block" images of preconfigured systems. That means you cannot change/specify/modify the file system of the boot image. – John Hanley Feb 23 '21 at 20:31

The doc you share is for COS, not for CentOS or any other OS. In particular you can set ext4 for additional disks you attach to your VM but not for the boot disk.

So the short answer is No.
