Thanks @Achelous - done, this is exactly the problem and knowing it's 1/32 means I can at least fix to 8GB for now.

@iusrlinearb

I noticed this bug in zfs a few months ago. It doesn't let you set zfs_arc_max to a value less than the default arc_c_min, which is 1/32 of all RAM.

I've raised a GitHub issue here:

https://github.com/openzfs/zfs/issues/10157

Please feel free to comment on the issue if you think you're seeing the same thing.

I'm struggling to stop zfs from consuming lots of RAM.

# cat /proc/spl/kstat/zfs/arcstats | grep c_max
c_max                           4    135097968640

If I look at arcstats, I see it growing rapidly towards c_max:

# cat /proc/spl/kstat/zfs/arcstats | grep size
size                            4    89817294664
[snipped the rest]

I've tried the obvious things. E.g. adding options zfs zfs_arc_max=5368709120 into /etc/modprobe.d/zfs.conf (and rebooting), adding zfs.zfs_arc_max=5368709120 to the end of my GRUB_CMDLINE_LINUX_DEFAULT and grub-mkconfig, rebooting.

I can see that the values are correctly being picked up - e.g. # cat /sys/module/zfs/parameters/zfs_arc_max 5368709120

Have looked at the wiki, for example https://wiki.archlinux.org/index.php/ZFS#ZFS_is_using_too_much_RAM

Also searched forums for zfs_arc_max but no useful messages. Anywhere else I should look? Thanks.

@LinuxIsBest,

iusrlinearb,

Doesn't appear to build, at least on my system.

zfs-0.8.3.tar.gz ... FAILED (unknown public key 6AD860EED4598027)
==> ERROR: One or more PGP signatures could not be verified!

This package doesn't support people who have failed to read the wiki page https://wiki.archlinux.org/index.php/Makepkg, or cannot interpret error messages.

I'm using zfs-dkms on x86_64 5.4.25-2-lts is it normal to see the following in boot logs?

mars 16 07:04:09 smicro kernel: zlua: loading out-of-tree module taints kernel.
mars 16 07:04:09 smicro kernel: zlua: module license 'MIT' taints kernel.

Great idea adding the 5.5 patch. Now that ZFS fixed SIMD support I upgraded for the first time in over a year from kernel 4.19 and it was painless. Thank you.

@sphere101: went from 5.4.15-arch1-1 to the latest today (5.5.7.arch1-1) and it built just fine.

Has anyone tested this latest zfs-dkms 0.8.3-2 with the 5.5.X kernel and latest gcc? If so, what is the process? Upgrade zfs-dkms and zfs-utils followed by a system update pacman -Syyu? Thank you.

@mikeyyve: compiles. The filesystem is mountable
