https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265424 Bug ID: 265424 Summary: vfs.zfs.arc_min ignored in /boot/loader.conf but works in /etc/sysctl.conf Product: Base System Version: 13.1-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jon@xyinn.org Hello, I'm currently running (but most likely also affects 13.1-RELEASE): FreeBSD 13.1-STABLE #0 stable/13-n251909-fa872a4bf71: Sun Jul 24 10:33:02 EDT 2022 root@leslie:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 >From my experiments, it seems that `vfs.zfs.arc_min` is ignored in /boot/loader.conf but it works in /etc/sysctl.conf. I'm not sure if it's related to a race condition or just the linear sequence of execution not considering the arc min (maybe too early?). Using quotes or not made no difference. The interesting this is that `vfs.arc.arc_max` works fine in /boot/loader.conf, and in /etc/sysctl.conf (as stated in 20.6.1 of the documentation for both tunables). These are my settings: # ZFS Tuning vfs.zfs.arc_min="4294967296" vfs.zfs.arc_max="8589934592" vfs.zfs.prefetch.disable="1" If you place those in /boot/loader.conf, only `arc_max` and `prefetch.disable` will be set properly, `arc_min` will be 0. If I place the same exact stuff in /etc/sysctl.conf, all of them will be set properly. - Jonathan -- You are receiving this mail because: You are the assignee for the bug.home | help
