Fixes: #11305 Fixes: #3260 Related: #11456 So, here's what happens in the described scenario in #11305. A unit goes down, and that triggeres stop jobs for the other two units as they were bound to it. Now, the timer for manager triggered restarts kicks in and schedules a restart job with the JOB_FAIL job mode. This means there is a stop job installed on those units, and now due to them being bound to us they also get a restart job enqueued. This however is a conflicts, as neither stop can merge into restart, nor restart into stop. However, restart should be able to replace stop in any case. If the stop procedure is ongoing, it can cancel the stop job, install itself, and then after reaching dead finish and convert itself to a start job. However, if we increase the timer, then it can always take those units from inactive -> auto-restart. We change the job mode to JOB_REPLACE so the restart job cancels the stop job and installs itself. Also, the original bug could be worked around by bumping RestartSec= to avoid the conflicting. This doesn't seem to be something that is going to break uses. That is because for those who already had it working, there must have never been conflicting jobs, as that would result in a desctructive transaction by virtue of the job mode used. After this change, the test case is able to work nicely without issues.
