[systemd-devel] [EXTERNAL] Re: ExecStop doesn't get called when service crashes

[Baskaran, Vinothkumar]

Hi Reindal,

Thanks for the inputs.

In my case, the service is successfully started. The pre-script's return status is also success. Please find the output below. Still, ExecStop doesn't get invoked. I tried replacing it with ExecStopPost, it gets invoked successfully.  But, ExecStopPost cannot be used, since it gets invoked on failed cases too. Please let me know if I need to collect more information to investigate further.

yes, the docs:
https://urldefense.com/v3/__https://www.freedesktop.org/software/systemd/man/systemd.service.html__;!!CQl3mcHX2A!XMPI4FzT0dPBtcTPcJHQ0uoBtgTQQGG7Jx81VeUd35HN-KqSWIh7zza7ga4FSP38Sqlii7ebRg$

ExecStop=
Note that the commands specified in ExecStop= are only executed when the service started successfully first. They are not invoked if the service was never started at all, or in case its start-up failed, for example because any of the commands specified in ExecStart=, ExecStartPre= or ExecStartPost= failed (and weren't prefixed with "-", see above) or timed out. Use ExecStopPost= to invoke commands when a service failed to start up correctly and is shut down again

ExecStopPost=
Additional commands that are executed after the service is stopped. This includes cases where the commands configured in ExecStop= were used, where the service does not have any ExecStop= defined, or where the service exited unexpectedly
