Powering on a virtual machine fails after a storage outage with the error: could not open/create change tracking file (2009244)

Symptoms

  • Virtual machine does not power on after a storage outage.
  • You see the error:

    could not open/create change tracking file vmdk_file_name

  • There are no CTK variables on the virtual machine configuration (.vmx). For more information, see vMotion fails at 78% with the error: Could not open change tracking file (2001004).
  • When the virtual machine is powered on, you see an error similar to:

    invalid signature change in tracking file

Cause

This issue occurs when the filename-ctk.vmdk file has been created but has not been cleared since.

Resolution

To resolve this issue, remove or rename the filename-ctk.vmdk file.

To remove or rename the filename-ctk.vmdk file:
  1. Remove the hard disk specified in the error message from the virtual machine.
  2. Open a Secure Shell session to the host. For more information, see Using Tech Support Mode in ESXi 4.1 and ESXi 5.0 (1017910).
  3. Navigate to the virtual machine's folder:

    (/vmfs/volumes/GUID/vm_name)

  4. Remove or rename the filename-ctk.vmdk file.
  5. Re-add the hard disk back to the virtual machine.
  6. Edit the descriptor file (.vmdk) and remove or comment out any references that specify use of a ctk file.
  7. Power on the virtual machine.
