MongoDB jepsen test error -- /var/log/mongodb/mongod.stdout: No such file or directory

[sasoripathos]

Hi, I recently is running the provided jepsen tests for MongoDB. When I just ran within the provided Vagrant VM setup. The test for replica set did not start properly, the error was something like:

/var/log/mongodb/mongod.stdout: No such file or directory

With investigation, I believe the root cause is the code for installing MongoDB was commented out. The code is here:

mallory/tests/jepsen/mongodb/src/jepsen/mongodb/db.clj

Line 282 in c754d6b

;; (install! test)

The fix is just uncomment this line.
