Description

This role configures a Systemd timer which generates Nimbus ERA files weekly.

The purpose of those is to save space by sharing the same historical data between nodes.

Read more about ERA files here.

Configuration

nimbus_era_files_timer_name: 'nimbus-era-files-update'
nimbus_era_files_timer_path: '/data/era'

nimbus_era_files_db_path: '/data/nimbus/data/db'
#nimbus_era_files_network: 'prater'

Management

The timer runs weekly with 12h random delay by default, but you can start it manually:
