Hi, I am in the process of creating disaster recovery documentation and I have two topics where I am not sure how to do it or even if it is possible. Is it possible to recover from a 100% mon data loss? Like all mons fail and the actual mon data is not recoverable. In my head I would thing that I can just create new mons with the same cluster ID and then start everything. The OSDs still have their PGs and data and after some period of time everything will be ok again. But then I thought that we use dmcrypt in ceph and I would need to somehow backup all the keys to some offsite location. So here are my questions: - How do I backup the lockbox secrets? - Do I need to backup the whole mon data, and if so how can I do it?
