We've recently run into this at work, and thought I'd point out the problem in case someone else stumbles across the issue. There is a race, as the initial task (setup to gather facts) goes to be executed on multiple hosts, if the directory ~/.fireball.keys does not exist, there will be multiple attempts to create it, depending on where the GIL is interrupted to hand over control around https://github.com/ansible/ansible/blob/62979efa140ce9659beac6442b51bd8efe35d4ba/lib/ansible/utils/encrypt.py#L98 When running multiple forks, each one can test that the directory does not exist, and attempt to create it. The first one that creates it will succeed without an issue, and the remainder will get an OSError that the file already exists. Since for the Travis CI runs you get a pristine environment each time, you'll see this occurring on a frequent basis. A simple fix is to ensure a single gather facts run is executed on only one of the target hosts using accelerate first, then follow this with the normal plays. A fix in the ansible code base would be to wrap the mkdir either with a threading lock or with something like the following: @contextlib.contextmanager def ignore_oserror_exists(): try: yield except OSError as ose: if ose.errno != errno.EEXIST: raise ose with ignore_oserror_exists(): os.makedirs(key_path, mode=0o700) Will file an issue with ansible shortly. -- Darragh -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
