Weeeeelp that's it we're going back to MTU 1500, and I'll put the jumbo frames in their own dedicated walled garden where they cannot hurt anyone

Enabling jumbo frames on your LAN is a great way to see which software and protocol have robust PMTU discovery. The answer lays somewhere between "'more than you would think" and "definitely not enough"

At least the only thing I noticed so far. SMB shares feels a bit more snappy but it could be only me. Also updated armbian from 6.6.x to 6.12.x, and loaded a custom device tree to improve stability, breaking the led watchdog in the process.

Besides that so far that's the only thing that broke moving everything to MTU 9000, for marginal CPU gains on my helios64 ARM NAS

Casually dropping

[boot]

command = ip link set dev eth2 mtu 1500

in /etc/wsl.conf because apparently jumbo frames are broken when using mirrored interfaces in WSL2

ZFS 2.3.0 is out https://github.com/openzfs/zfs/releases/tag/zfs-2.3.0

Include RAIDz expansion (switch from 5 to 6 disks without rebuilding your pool!), fast dedup (still not as good as it sounds, but at least not terrible!), direct IO... This is truly a leap forward.

I got as far as to install GCC to compile the CPAN dependencies before realizing that the package has an issue. I was looking at the apt history log for a perl upgrade and saw the original 9.0.0 install and the 9.0.1 upgrade side by side - and one of them was amd64 -_-'

I have such mistrust into python and Perl package management that "The following modules failed to load: DBI EV XML::Parser::Expat HTML::Parser JSON::XS Digest::SHA1 YAML::XS Sub::Name" immediately got me thinking there was something wrong between my perl version, my OS setup and the vendored CPAN from https://lyrion.org/getting-started/

Just lost like 3 hours because I tried to install an amd64 package on an aarch64 system 🤦‍♂️-- The thing was perl so it almost worked, and simply crashed at startup with a cryptic message about not being able to load some modules (that were compiled for x64 I guess)
