Disallow removing the featureCompatibilityVersion document

    XMLWordPrintableJSON

Details

    • Fully Compatible

    Description

      Removing the featureCompatibilityVersion document, dropping the admin.system.version collection, or dropping the admin database should fail. This can either fail by fasserting or by aborting the transaction and returning an error. If we fail by fasserting, we should be able to recover using the startup parameter in SERVER-29452.

      Mongod 3.6 must always have the featureCompatibilityVersion document, as described in SERVER-29452.
