<!-- Source: https://docs.redpanda.com/streaming/25.3/reference/rpk/rpk-cluster/rpk-cluster-storage-unmount.md -->

Unmount a topic from the Redpanda cluster and secure it in [Tiered Storage](https://docs.redpanda.com/streaming/25.3/reference/glossary/#tiered-storage).

This command performs an operation that:

1.  Rejects all writes to the topic.

2.  Flushes data to Tiered Storage.

3.  Removes the topic from the cluster.


Key Points:

-   During unmounting, any attempted writes or reads will receive an `UNKNOWN_TOPIC_OR_PARTITION` error.

-   The unmount operation works independently of other topic configurations like `remote.delete=false`.

-   After unmounting, the topic can be remounted to this cluster or a different cluster if the log segments are moved to that cluster’s Tiered Storage.
