MononcQc posted:So yes in production you'll probably want something that restarts software, reboots servers, or allows you to add or remove them, because otherwise you'll slowly end up with not enough machines to keep going. But you won't fall in the case where, say, the connection between servers falls in a bad state and a 3 hours timeout resolves it later on and all of a sudden one end thinks the other was crashed but the other just thought things were slow. I think Paxos has the requirement that a machine that goes down can be brought back up in the same state it was in before it fell over. Faulty RAID controllers do not seem to be what it's designed to cope with.

Faulty RAID controllers do not seem to be what it's designed to cope with. Paxos has implicit mechanisms to deal with new nodes joining the quorum (you can use Paxos to configure Paxos), where it can play catch-up. This was covered in the Google paper about using it in Chubby: quote:5.1 Handling disk corruption The catch-up mechanism exists because nodes in multi-paxos may lag behind: quote:Each replica maintains a locally persistent log to record all Paxos actions. When a replica crashes and subsequently recovers, it replays the persistent log to reconstruct its state prior to crashing. Replicas also use this log when helping lagging replicas to catch up. The mechanisms for this are not in the google paper, but something as simple as submitting a no-op write for an existing entry (I no-op write entry 1, members of the quorum should answer back with the value that was accepted already) are implicit to the protocol. This is likely slow as you may need to replay the entire log history, but Paxos doesn't directly care about speed. Optimizations would likely have you handing off logs or a snapshot from another member on a side-channel, but I don't recall that stuff in either of the original papers (the most that is mentioned from memory is keeping a quick log of most recent transactions for network blips, not full on corruption).

This was covered in the Google paper about using it in Chubby: Well this is the sort of buttressing I was talking about. It seems you need some sort of reliable database underlying Paxos to make it work operationally.

Yeah, it assumes reliable storage is there, can deal with failures if it can detect them locally, but does not necessarily need persistent storage. It's not always necessary if you decide to go for the crash-stop model: once the node knows it crashed, it wipes its state clean and recovers from peers. That's what Scalaris does, although I couldn't say how well it fares in production given how few people use it.

scons seems like a nice build system if you're the kind of person who lives in a nightmare where you have to think about build systems. thats my programming story for the day

it's more of a ding on the maturity of scons. old mistakes are new mistakes are old mistakes. you fixed your issue by invoking 'do it like make, goddamn it' the best thing about scons is that you can write things in python. the worst thing about scons is that you have to write things in python.
