In these reindex scenarios, the secondary cluster will perform a complete 24WAL replay, which can take a long time and is a partially blocking operation. 25 26This is fixed in [Vault 271.1.3](https://github.com/hashicorp/vault/blob/master/CHANGELOG.md#113-june-5th-2019), 28and we recommend upgrading to Vault 1.1.3+ rather than any prior 1.1.x version. 29We also strongly recommend upgrading your Vault cluster to 1.1.3 if you are 30running Vault Enterprise 1.1.0, 1.1.1 or 1.1.2. 31
