| Description |

If a replica set is running without journaling, the writeConcernMajorityJournalDefault option in the replica set config should be set to false. If this isn't done there will be multiple issues, including:
This update should also be backported to v3.4 and v3.2. https://github.com/mongodb/mongo/commit/918524be973eb056909f035df141b0dd5765ead1 |

For 3.6, I think the recommendation should be something along the lines of "don't do this and here's why." |

We have a documented recommendation that users not run replica sets on WT with journaling turned off, per https://jira.mongodb.org/browse/DOCS-10925. The --nojournal option is deprecated on 3.6 for replica sets with WT. We could modify that recommendation to something like "You really shouldn't do this, but if you absolutely must, then you should also set writeConcernMajorityJournalDefault to false." But it seems better to keep the recommendation to a simple "don't do it." I'm proposing to add the information about writeConcernMajorityJournalDefault to the 3.4 and 3.2 docs but leave it out of the 3.6 docs. |
