Vmware Cloud Foundation (VCF) does not support parallel upgrades of vCenter

Products

• VMware Cloud Foundation

Issue/Introduction

Symptoms:
VCF does not support parallel upgrades of vCenter server because the underlying vCenter does not provide this support.

Environment

VMware Cloud Foundation 4.x
VMware Cloud Foundation 3.x

Cause

vCenter patch failed while changing the  ownership of vpostgres component.  The command “chown -R vpostgres:vpgmongrp /storage/archive/vpostgres” failed to execute successfully.

This generally occurs when vCenters are upgraded in parallel. Refer About the Upgrade Process of the vCenter Server Appliance for more information.

Resolution

To resolve the issue, follow the workaround. Avoid upgrading vCenter in parallel.

Workaround:

To workaround the issue, please follow the below mentioned steps:

1. Revert to snapshot before stage directory cleanup (after vpostgres failure).

2. Login to vcenter using ssh and run the below command.
   chown -R vpostgres:vpgmongrp /storage/archive/vpostgres

3. Reset resume count on vCenter using below:
   sqlite3 /storage/db/patching.db
   update config set _value=0 where _config='resume-count';

4. Login to SDDC Manager in VCF and navigate to updates/patches section of the workload domain. Upgrade should be available in VCF.

5. Once the upgrade is available, Retry the upgrade.
