SDDC Manager 5.2.1 UI fails to start after reboot

Products

• VMware SDDC Manager

Issue/Introduction

When accessing the SDDC UI via browser the image below is presented:

Environment

VMware Cloud Foundation 5.2.1

Cause

A known RACE condition with nginx and the sddc-manager-ui service when an OS level reboot is performed. 

Resolution

Workaround:

1. SSH into the SDDC Manager Appliance with the vcf user and then elevate to root with su.

2. Take a backup of the sddc-manager-ui-app.service conf file. 

cp -p /etc/systemd/system/sddc-manager-ui-app.service /home/vcf/

IMPORTANT: Do not put the backup file within the /etc/systemd/system/ directory. This will cause stability issues in future updates.


3. Edit this file using the vi editor:

vi /etc/systemd/system/sddc-manager-ui-app.service

4. In the [Unit] section of the file, find the entry starting with 'After=' and add nginx.service

For example,

[Unit]
After=sddc-manager-ui-db.service nginx.service

5. Reload the system configuration

systemctl daemon-reload

6. Reboot the SDDC Manager Appliance and verify all services start as expected. 

reboot -f
