Validator Maintenance
Common validator maintenance steps
Node operators are required to routinely update their validator's version of sx-node, maintain a high uptime (99%), and monitor the health of their instances. This section will evolve over time to include links and how-to guides essential to the duties of a node operator.
Updating to the latest version of sx-node
From within your validator
directory:
git pull && chmod +x update_validator.sh && ./update_validator.sh "$(curl http://checkip.amazonaws.com)"
Running your node in safety mode
At times you might be required by an SX Admin to run your node in safety mode. This mode ensures your validator can only sync up to trusted validators. If asked, please follow the steps below:
Stop the sx-node service:
sudo systemctl stop sx-node
Clear the data-dir within your
sx-node
directory:rm -rf data/blockchain/ data/trie/ data/consensus/snapshots data/consensus/metadata
Add the
bootnode_only_sync: true
field to theconfig.yml
and save that file.For example your
config.yml
file might look something like:chain_config: /home/heisenberg/validator/sx-node/genesis.json data_dir: /home/heisenberg/validator/sx-node/data block_gas_target: 0x3938700 grpc_addr: 0.0.0.0:10000 jsonrpc_addr: 0.0.0.0:10002 network: libp2p_addr: 0.0.0.0:10001 nat_addr: 127.0.0.1 bootnode_only_sync: true seal: true tx_pool: price_limit: 1000000000 log_level: DEBUG gasprice_block_utilization_threshold: 0.95 data_feed: verify_outcome_api_url: https://outcome-reporter.sx.technology/api/outcome
Restart the sx-node service:
sudo systemctl daemon-reload && sudo systemctl restart sx-node
