Abstract
A storage cluster of symmetric nodes includes a data privacy scheme that implements key management through secret sharing. The protection scheme preferably is implemented at install time. At install, an encryption key is generated, split, and the constituent pieces written to respective archive nodes. The key is not written to a drive to ensure that it cannot be stolen. Due to the secret sharing, any t of the n nodes must be present before the cluster can mount the drives. To un-share the secret, a process runs before the cluster comes up. It contacts as many nodes as possible to attempt to reach a sufficient t value. Once it does, the process un-shares the secret and mounts the drives locally. Given bidirectional communication, this mount occurs more or less at the same time on all t nodes. Once the drives are mounted, the cluster can continue to boot as normal.
