| Steps To Reproduce: | A slightly more detailed repro script and logs are attached, but the gist of it is the following:
The new secondary has FCV=3.6, but local collections do not have UUIDs. Regular (non-local) collections do have the correct UUID however. Per suggestions, the fix may just be not to skip shard servers here: https://github.com/mongodb/mongo/blob/r3.6.0/src/mongo/db/repl/initial_syncer.cpp#L1098-L1119 |

| Description |
|
When a secondary is added to a shard replset with FCV=3.6, it does not generate UUIDs on the local database. |
