vRSLCM Easy Installer deployment fails while initializing postgres

vRLSCM 8.x deployment through Easy Installer or vCF might fail while initializing postgres database with below exception

Below snippet is taken from /var/log/bootstrap/firstboot/firstboot.log

2022-06-22 11:45:03.719 UTC [3053] DEBUG:  proc_exit(-1): 0 callbacks to make

You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    /opt/vmware/vpostgres/current/bin/pg_ctl -D /storage/db/pgdata -l logfile start

Warning: your password will expire in 5 days

When it works following output is expected

The cause of the problem is that vmware-studio invokes firstboot script twice.

This retriggers postgres configuration again while other one (original firstboot) was failed to configure fully.

Note: "In case of VCF environment, execute steps 1 to 7"

1. SSH to SDDC Manager appliance and switch to root user

2. Open /etc/vmware/vcf/domainmanager/application-prod.properties in a text editor.

3. Add this line vrslcm.firstboot.timeout.period.in.minutes=15

4. Save the file and close the editor.

5. Restart the Domain Manager with: systemctl restart domainmanager

6. Wait 2 minutes for the service to restart. You can check status using: systemctl status domainmanager

7. Run the "Deploy vRealize Suite Lifecycle Manager" operation from the SDDC Manager UI.

8. Delete the postgres directory and run postgres configuration script. Incase of a vcf environment, customer has to perform this within 5mins or quicker. Once vRSLCM appliance gets deployed, login to Web Console from vCenter Server and perform following steps:

1. rm -rf /storage/db/pgdata/
2. /etc/bootstrap/firstboot.d/02-configure-postgres.sh
3. /etc/bootstrap/firstboot.d/20-start-services

9. Reboot vRSLCM 

10. Check vpostgres status 
service vpostgres status

if in case admin@local password does not work , then use below command to reset it

/opt/vmware/share/vami/vami-vlcm-passwd-reset

Reboot Appliance and Login

Verification

• After this workaround, vRSLCM UI will be up and running

• Check systemctl status vpostgres is in running state.
