Symptoms:

Environment

VMware vCenter Server Appliance 6.7.x

Cause

  • Checking the serverlog.stderr log we find the following:
Starting service process with pid: 17384.
LOG:  skipping missing configuration file "/storage/db/vpostgres/postgresql.conf.repl"
LOG:  skipping missing configuration file "/storage/db/vpostgres/postgresql.conf.repl"

2019-11-21 14:52:54.932 UTC 5dd6a4c6.43e8 0   HINT:  Either another server is starting, or the lock file is the remnant of a previous server startup crash.
2019-11-21 14:52:54.932 UTC 5dd6a4c6.43e8 0   LOG:  database system is shut down
 
  • The vPostgres Service is failing to start because the contents of ".s.PGSQL.5432.lock" database lock file are missing.

Resolution

Follow the below steps to solve this issue:

1. Take a Snapshot of the vCenter Server Appliance virtual machine.
2. Login to the Appliance shell via SSH.
3. Got to this location : /var/run/vpostgres
4. Locate the file named as .s.PGSQL.5432.lock
5. Open the file in editor : vi .s.PGSQL.5432.lock
6. Enter the following in the file:

21810
/storage/db/vpostgres
1574278293
5432
/var/run/vpostgres
.s.PGSQL.5432.lock (END)


7. Save the file and restart all the vCenter Services.
