PKS Upgrade failure at the step "Installing Enterprise PKS"

Products

• VMware Cloud PKS

Issue/Introduction

Symptoms:

• An Enterprise PKS upgrade fails at the step "Installing Enterprise PKS".
• One or more snapshots are present on the PKS VM.
• BOSH reports that the PKS VM is failing.
• The PKS API is inaccessible.
• In the BOSH task logs you see messages similar to the following:

"Unknown CPI error ''Unknown'' with message ''Invalid configuration for device ''0''.'' in ''detach_disk'' CPI method

 

Note: The preceding log excerpts are only examples. Date, time, and environmental variables may vary depending on your environment.

Environment

VMware PKS 1.x

Cause

BOSH will try to mount the PKS VM disk and would fail with the error ''Invalid configuration for device ''0''.'' in ''detach_disk'' CPI method. This occurs whenever there is any snapshot being taken on the PKS VM (or on any VM created by BOSH).

Resolution

Delete any snapshots taken of the PKS VM.

Additional Information

Snapshots should not be taken on any BOSH created VMs as these VMs have to be managed only by BOSH and any manual configuration of the VM will result in errors.
