If you receive this error when trying to build, it is because you have not imported the GPG keys used for verification.

==> ERROR: One or more PGP signatures could not be verified!

You have two options:

1) Import the two keys into your keyring. ArchWiki article. You can find the key IDs in the PKGBUILD file, in the validpgpkeys array. (recommended)

2) Alternatively, you can skip this verification by passing the --skippgpcheck argument to makepkg when building. (not recommended)

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,

Comment deleted, next time you attempt personal attacks on a Trusted User I'll just suspend your account.

iusrlinearb,

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

zfs-0.8.3.tar.gz ... FAILED (unknown public key 6AD860EED4598027)

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.
