# Part 5 — Watch the sync

Lighthouse (beacon) syncs in minutes via checkpoint sync. Geth (execution) takes hours to a day-plus and fills most of the disk. Monitor progress:

```bash
# Disk filling is the simplest progress bar (climbs toward ~1.1 TB):
df -h /blockchain

# Detailed execution sync state:
docker exec execution geth attach --exec "eth.syncing" \
  /blockchain/execution/geth/geth.ipc

# Follow logs (Ctrl+C stops watching, not the container):
docker logs -f --tail=50 execution
docker logs -f --tail=50 beacon
```

{% hint style="info" %}
**How you know it's fully synced:** `eth.syncing` returns `false`, and the beacon log shows `exec_hash: ... (verified)` with no "Head is optimistic" warnings. At that point the RPC is fully trustworthy.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://dozza.gitbook.io/pulsechain_node_guide/part-5-watch-the-sync.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
