> Had a bad value in info:state field in meta and it made it so couldn't start up the cluster; loadMeta would not succeed. If a bad state, should note it, compensate, and move on.
> The bad entry was an own goal that happened while trying to fix other issues in a pre-hbck2 cluster.
> Here was the exception:
