+```
+## Monitoring stack sync progress
+Both go-ethereum and lighthouse will engage in an initial chain sync phase that will last up to several hours depending on hardware performance and network capacity.
+Syncing can be monitored by looking for these log messages:
+```
+Jul 24 12:34:17.001 INFO Downloading historical blocks           est_time: 5 days 11 hrs, speed: 14.67 slots/sec, distance: 6932481 slots (137 weeks 3 days), service: slot_notifier

+```
+Once synced up these log messages will be observed:
+```
+INFO Synced                                  slot: 6952515, block: 0x5bcb…f6d9, epoch: 217266, finalized_epoch: 217264, finalized_root: 0x6342…2c5c, exec_hash: 0x8d8c…2443 (verified), peers: 31, service: slot_notifier

+```
+## Clean up
+
+Stop the stack:
+```
+$ laconic-so deployment --dir mainnet-eth-deployment stop
+```
+This leaves data volumes in place, allowing the stack to be subsequently re-started.
+To permanently *delete* the stack's data volumes run:
+```
+$ laconic-so deployment --dir mainnet-eth-deployment stop --delete-data-volumes
+```
+After deleting the volumes, any subsequent re-start will begin chain sync from cold.
+## Data volumes
+Container data volumes are bind-mounted to specified paths in the host filesystem.
+The default setup (generated by `laconic-so deploy init`) places the volumes in the `./data` subdirectory of the deployment directory:
+```
+$ cat mainnet-eth-spec.yml
+stack: mainnet-eth
+volumes:
+  mainnet_eth_config_data: ./data/mainnet_eth_config_data
+  mainnet_eth_geth_1_data: ./data/mainnet_eth_geth_1_data
+  mainnet_eth_lighthouse_1_data: ./data/mainnet_eth_lighthouse_1_data
+```
+A synced-up stack will consume around 900GB of data volume space:
+```
+$ sudo du -h mainnet-eth-deployment/data/
+150M    mainnet-eth-deployment/data/mainnet_eth_lighthouse_1_data/beacon/freezer_db
