Yep, good point. I'm not familiar with systemd, upowerd, and UPS integration and policies - but for sure there are use cases where heavy write workloads can so thoroughly dirty a filesystem that it can take many minutes to flush to stable media. But I expect that the design of this system accounts for the peak usage time to stop all processes cleanly. You don't really want to lose that data. But at a certain point, you'd want to SIGKILL everything anyway, so that there's time for sync() to return. The systemd reboot/shutdown does umount or remount read-only; both fully flush all file system data and metadata to stable media. But this might take longer than just sync() so I think in such cases you really want sync() to succeed, and the shutdown is nice to have. -- Chris Murphy _______________________________________________ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org
