Minor - P4 Not sure which component this is but doing mongod --help you get
Storage options:
--storageEngine arg what storage engine to use - defaults
to wiredTiger if no data files present
--dbpath arg directory for datafiles - defaults to
/data/db
--directoryperdb each database will be stored in a
separate directory
--noprealloc disable data file preallocation - will
often hurt performance
--nssize arg (=16) .ns file size (in MB) for new databases
--quota limits each database to a certain
number of files (8 default)
--quotaFiles arg number of files allowed per db, implies
--quota
--smallfiles use a smaller default file size
--syncdelay arg (=60) seconds between disk syncs (0=never,
but not recommended)
--upgrade upgrade db if needed
--repair run repair on all dbs
--repairpath arg root directory for repair files -
defaults to dbpath
--journal enable journaling
--nojournal disable journaling (journaling is on by
default for 64 bit)
--journalOptions arg journal diagnostic options
--journalCommitInterval arg how often to group/batch commit (ms)
Of these a bunch are only MMAPV1 applicable. Using one of those options with 3.3.9 gets you just this in the logs:

Of course, wired tiger being default, this option is apparently just being ignored.
