Read-Only File System after Upgrade Kernel under CentOS 7

---

Hi all,
   I upgraded the kernel of CentOS 7 to 4.11.4, and reboot the VM. After that, I cannot change anything in the system. No matter what I do, it says Read-only file system.
   I want to work with the latest kernel, what's the correct way to upgrade kernel under CentOS 7 on Google Cloud Engine?

  Thank you very much!
