| To help you understand which case your node is in, the ``GET /health/diagnose`` | ||
| endpoint remains available and returns information about the current status of | ||
| ``etcd`` and its database, including logs (refer to the API documentation). |

Should we clarify that it might take a while for the transition into the Failed state to complete, e.g. due to internal retries and timeouts? But that this is necessary to recover from failures and to not enter the Failed mode too often.

| - *isolate* the node with the ``POST /cluster/force-new`` endpoint, which will | ||
| irreversibly forget all other cluster members and restart ``etcd`` with the | ||
| data present on disk. If the underlying failure was cluster-related, the node | ||
| will transition out of the _Failed_ state. |

Should we mention what state it ends up in? The answer might depend on whether you use unattended boot.
