[Bug 296166] Warning: sysctl vfs.zfs.arc_max is deprecated

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=296166

--- Comment #2 from Ahmad Nizam Ramli <[email protected]> ---
As suggested, I added boot_verbose="YES" to /boot/loader.conf and restarted the
system. However, after the restart, the warning previously seen in dmesg
(WARNING: sysctl vfs.zfs.arc_max is deprecated) did not appear.

[21:10]root@nas:~ # cat /boot/loader.conf | grep boot
boot_verbose="YES"
[21:10]root@nas:~ # dmesg | grep zfs
[21:10]root@nas:~ # dmesg | grep arc
[21:10]root@nas:~ #

Afterward, I removed the boot_verbose="YES" line from /boot/loader.conf and
restarted the system again. Following this restart, the warning still did not
appear. I am still using the same FreeBSD version (14.4-RELEASE-p6) and have
not performed any updates since I reported the bug.

[21:21]root@nas:~ # cat /boot/loader.conf | grep boot
[21:21]root@nas:~ # dmesg | grep zfs
[21:21]root@nas:~ # dmesg | grep arc
[21:21]root@nas:~ # uname -a
FreeBSD nas 14.4-RELEASE-p6 FreeBSD 14.4-RELEASE-p6 GENERIC amd64
[21:21]root@nas:~ #

I am not sure why the warning suddenly cleared after increasing the boot
verbosity, but it is no longer appearing. I do not have any third-party startup
scripts or monitoring tools that query ZFS ARC statistics. Since the warning is
gone, I believe we can close this case.
