@ -245,35 +245,48 @@ This list of limitations only reflects the latest version of GitLab. If you are
- Object pools for forked project deduplication work only on the **primary** node, and are duplicated on the **secondary** node.
- [External merge request diffs](../../merge_request_diffs.md) will not be replicated if they are on-disk, and viewing merge requests will fail. However, external MR diffs in object storage **are** supported. The default configuration (in-database) does work.
### Limitations on replication
### Limitations on replication/verification
Only the following items are replicated to the **secondary** node:
The following table lists the GitLab features along with their replication
and verification status on a **secondary** node.
- All database content. For example, snippets, epics, issues, merge requests, groups, and project metadata.
- Project repositories.
- Project wiki repositories.
- User uploads. For example, attachments to issues, merge requests, epics, and avatars.
- CI job artifacts and traces.
You can keep track of the progress to include the missing items in:
- [ee-893](https://gitlab.com/groups/gitlab-org/-/epics/893).
- [ee-1430](https://gitlab.com/groups/gitlab-org/-/epics/1430).

1. The integrity can be verified manually using [Integrity Check Rake Task](../../raketasks/check.md) on both nodes and comparing the output between them.
DANGER: **DANGER**
Data not on this list is unavailable on the **secondary** node. Failing over without manually replicating data not on this list will cause the data to be **lost**.
### Examples of data not replicated
Take special note that these examples of GitLab features are both:
- Commonly used.
- **Not** replicated by Geo at present.
Examples include:
- [Elasticsearch integration](../../../integration/elasticsearch.md).
- [Container Registry](../../container_registry.md). [Object Storage](object_storage.md) can mitigate this.
- [GitLab Pages](../../pages/index.md).
- [Mattermost integration](https://docs.gitlab.com/omnibus/gitlab-mattermost/).
CAUTION: **Caution:**
If you wish to use them on a **secondary** node, or to execute a failover successfully, you will need to replicate their data using some other means.
Features not on this list, or with **No** in the **Replicated** column,
are not replicated on the **secondary** node. Failing over without manually
replicating data from those features will cause the data to be **lost**.
If you wish to use those features on a **secondary** node, or to execute a failover
successfully, you must replicate their data using some other means.
