And before rebooting I did another sync, which took 130s, using 100% system time. This is the status output afterward: http://ue.tst.eu/6d0398c4184fdbef059e90a6bf454241.txt Is it normal that f2fs takes this long for a sync? What happens when, during shutdown, there is a timeout during umount and systemd shuts down anyway, or the fs doesn't get unmounted, will there be data loss because of rolling back? I am a bit concerned, because the filesystem was sitting idle for hours, and I expect a crash at that point to not lose any data due to reverting to a checkpoint. -- The choice of a Deliantra, the free code+content MORPG -----==- _GNU_ http://www.deliantra.net ----==-- _ generation ---==---(_)__ __ ____ __ Marc Lehmann --==---/ / _ \/ // /\ \/ / schm...@schmorp.de -=====/_/_//_/\_,_/ /_/\_\ ------------------------------------------------------------------------------ _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
