Haven't checked device logs just yet. These are RHEL7 systems with XFS
filesystems.
I've internally chalked this up to a "race condition", where multiple
Ansible process forks are trying to update the same file at nearly the same
time. As an experiment, I added the "serial" directive to the play and set
it to "1":
Example:
- name: Ensure all machines have /etc/hosts entries
become: true
hosts: [machines]
serial: 1
tasks:
- <blah>
I see the difference in Ansible's console output, where it is doing the
lineinfile call to one host at a time vice all at once. I've only run it a
few times after this change but have yet to see the empty file problem.
I'll continue running tests to ensure this is a good fix.
