Unsealing a single Vault server in a cluster unseals all Vault servers in that cluster.
Unsealing a single Vault server in a cluster unseals all Vault servers in that cluster.
In a HashiCorp Vault cluster, each Vault server (node) must be unsealed individually. The unsealing process involves the decryption of certain critical information necessary to start the Vault server. This process ensures an additional layer of security and resilience by requiring that each node is independently unlocked, rather than relying on a single node to unseal all others.
B HashiCorp Vault uses the "unsealing" process to unlock and access encrypted data in persistent storage. When Vault is configured as a cluster with multiple servers (nodes), it is generally required to perform the unsealing process on each of the nodes. The main reason for this is to provide an additional layer of security and resilience. In a clustered environment, Vault divides and distributes the unsealing keys among the nodes. Therefore, each node in the cluster must be independently unsealed in order for the system as a whole to access the encrypted data. In summary, in a HashiCorp Vault cluster, unsealing must generally be performed on all nodes to ensure proper access to encrypted secrets. This helps ensure availability and redundancy in case of failures on some nodes in the cluster
Each server needs to be individually unsealed.
