I would prefer not to enforce a node minimum. |

|
Note that for development purposes it is common to just run with a single config server. (Just calling it out just in case.) |

Should we add a minimum number of nodes? |

I'm planning to tackle this ticket in the near future. schwerin, spencer, renctan have you decided what all we would like to forbid? |

|
We should also consider forbidding slaveDelay, and perhaps buildIndexes:false, schwerin, what do you think? |
| Comment by Eric Milkie [ 01/Jul/15 ] |
|
Yes, the answer is that in particular for CSRS, we want to make it very hard to have a situation where a primary is up but no writes are replicated to a majority of nodes. |

I believe it has to do with how read committed and arbiters interact, schwerin had a more concrete understanding why. |

This ticket needs a definitive list of validation points in the description. |
