# Description
|
|
|
|
This role configures a Systemd timer that periodically purges the Nimbus node database to test the sync process. Optionally it can use the [trusted node sync](https://nimbus.guide/trusted-node-sync.html) functionality.
|
|
|
|
# Configuration
|
|
|
|
In order to purge database of `beacon-node-mainnet-stable` weekly and sync it from trusted node:
|
|
```yaml
|
|
nimbus_db_purge_node_service_name: 'beacon-node-mainnet-stable'
|
|
nimbus_db_purge_node_service_path: '/data/{{ nimbus_db_purge_node_service_name }}'
|
|
nimbus_db_purge_node_network_name: 'mainnet'
|
|
nimbus_db_purge_timer_frequency: 'weekly'
|
|
nimbus_db_purge_truster_node_api_url: 'http://localhost:9300'
|
|
nimbus_db_purge_trusted_node_sync_enabled: true
|
|
```
|
|
|
|
# Management
|
|
|
|
The Systemd timer can be managed with `systemctl`:
|
|
```
|
|
> sudo systemctl -o cat status purge-beacon-node-mainnet-stable
