• The version of open-vm-tools is still 9.4.6 after the operating system upgrade.

Cause

This issue occurs due to the Operating System update mechanism of CoreOS no longer updates the /usr/share/oem/ partition.

Resolution

To work around this issue deploy a new CoreOS installation and copy the open-vm-tools from this installation.

1. Stop the running vmtoolsd service with this command:
   
   sudo systemctl stop vmtoolsd
   
   
2. Backup the /usr/share/oem/cloud-config.yml file.
3. Deploy a new CoreOS virtual machine using the same build as the affected virtual machine.
4. Verify that the deployed virtual machine contains the correct version of open-vm-tools.
5. On the affected virtual machine, delete all files under /usr/share/oem/.
6. Copy the files in the /usr/share/oem/ directory from the freshly installed virtual machine to the affected virtual machine.
7. Open the cloud-config.yml that was backed up earlier and modify the version-id to the version from step 3.
8. Copy the cloud-config.yml file to /usr/share/oem/.
9. Reboot the virtual machine.
