Then I did this for 8 minutes, strace -c -f -p $(pgrep systemd-journal) https://paste.fedoraproject.org/paste/Uzc2KhkkaqLOU8USLd38B15M1UNdIGYhyRLivL9gydE= So 6 fsyncs in 8 minutes; more than 1 per 5 minutes, but not nearly as many as I thought. So maybe as you say it's just memory mapped activity I'm seeing with state and filefrag. -- Chris Murphy _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
