https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=296166 --- Comment #1 from Jose Luis Duran <jlduran@FreeBSD.org> --- Just as a reference, this waring was MFC'd to stable/14 in fdf8dc1a01a603cbd1f9349068e43c7d8c609969. Having both vfs.zfs.arc.max and vfs.zfs.arc_max is expected, as the latter is kept as a deprecated compatibility alias. The warning is emitted when something accesses the deprecated sysctl, not because the alias exists. There are no remaining references to vfs.zfs.arc_max in 14.4 (aside from an unrelated ZFS test), so something on your system is likely still querying the old name during boot. At this point, I'd suggest increasing the boot verbosity[^1] (or enabling debug output[^2]) to identify what is triggering the lookup. It may also be worth checking any third-party startup scripts or monitoring tools that query ZFS ARC statistics. [^1]: Add to /boot/loader.conf: boot_verbose="YES" [^2]: Add to /etc/rc.conf: rc_info="YES" and rc_debug="YES" -- You are receiving this mail because: You are the assignee for the bug.home | help
