Problem definition

Current CentOS versions, which are being installed and configured during re-image procedure, have quite strict limits for log rotation. Normally only last day is recorded. This may be a problem when working with long test runs or doing post-mortem analysis.

To fix this we need to increase limits.

Configuration

  • Edit /etc/systemd/journald.conf. Make sure that following is defined: 
    Storage=persistent
SystemMaxUse=20G
  • Restart systemd-journald. 
    systemctl restart systemd-journald
