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.

Configuration

nimbus_era_files_timer_name: 'nimbus-era-files-update'
nimbus_era_files_timer_path: '/data/era'
nimbus_era_files_nclidb_path: '/data/nimbus/repo/build/bin/ncli_db'
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:

 > systemctl -o cat status nimbus-era-files-update
