VCPG-67-000004 - VMware Postgres must be configured to overwrite older logs when necessary.


Without proper configuration, log files for VMware Postgres can grow without bound, filling the partition and potentially affecting the availability of the VCSA. One part of this configuration is to ensure that the logging subsystem overwrites, rather than appending to, any previous logs that would share the same name. This is avoided in other configuration steps, but this best practice should also be followed.


At the command prompt, execute the following commands:

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c 'ALTER SYSTEM SET log_truncate_on_rotation TO 'on';'

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c 'SELECT pg_reload_conf();'
