Symptoms



L'aggiornamento di NMC riscontra un problema con la migrazione di Postgres dalla versione 9.2 alla versione 11 al seguente punto dei registri.

Da "pg_upgrade_server.log". 
command: "/opt/lgtonmc/postgres/9.2/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/nsr/nmc/nmcdb/pgdata" -o "-p 5432 -c autovacuum=off -c autovacuum_freeze_max_age=2000000000  -c listen_addresses='' -c unix_socket_permissions=0700" start >> "pg_upgrade_server.log" 2>&1
        pg_ctl: another server might be running; trying to start server anyway
        waiting for server to start....FATAL:  could not open lock file "/tmp/.s.PGSQL.5432.lock": Permission denied
         stopped waiting
        pg_ctl: could not start server
        Examine the log output.

From "install.log".

        186994:gstdbinit: pg_upgrade --check failed 
        Upgrade to Postgres 11 Failed. Failover to 9.2 binaries so that db can start

Cause

Si tratta di un raro caso limite in cui un processo ha un blocco sul file "/tmp/.s.PGSQL.5432.lock".

Resolution

Per risolvere questo problema, è necessario arrestare i servizi NMC ed eseguire nuovamente lo script "nmc_config" per eseguire manualmente la migrazione di Postgres: /opt/lgtonmc/bin/nmc_config

Di seguito è riportato l'output pertinente dello script dopo l'esecuzione corretta. (potrebbe essere necessario riavviare il sistema prima di eseguire nuovamente questo script se si verifica lo stesso problema).
  
Postgres 9.2 database detected. It will be migrated to Postgres 11
It may take a while to upgrade.....
Migration to Postgres 11 Successful.
The installation completed successfully.
