rpk cluster storage unmount

Unmount a topic from the Redpanda cluster and secure it in 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.
