Due to the secret sharing scheme, any t of the n nodes must be present before the cluster can mount the drives. Thus, 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. | 2008-11-20 |
