Abstract
A method of encryption key management in a storage system having a plurality of nodes and more than one key manager, performed by the storage system, is provided. The method includes setting, in a first atomic operation to a distributed store of the plurality of nodes, a version identifier to a new value, and writing shards of a key encryption key, to node-specific memory of the plurality of nodes. The method includes committing the shards of the key encryption key by updating, in a second atomic operation, a set of version identifiers in the distributed store including a current version identifier, responsive to finding no change to the new value of the version identifier.
