When standard filesystems like ext4 and xfs hit enough io errors,they unmount the filesystem. I find that this happens pretty reliably in AWS at least and I can't imagine the filesystem possibly continuing to do very much when 100% of the underlying data has disappeared.

That said, from further reading of the GCP docs, it does sound like if they detect a disk failure they will reboot the VM as part of the not-so-live migration.
