With a budget, colleagues and I would:

⚡️Reduce volunteer cash advances for events

⚡️Improve the #OpenZFS test suite and documentation

⚡️Organize East coast USA and European OpenZFS summits

⚡️Continue to improve #bhyve

⚡️Continue to improve community Audio/Video wisdom and equipment

⚡️Consider cloud service backup/export challenges (I got Google Drive mirroring to work!)

The money is out there but is firewalled.

If you believe in these same goals, please reach out to potential supporters.

In 2025 I introduced colleagues to over half a million USD in employment opportunities. Now I am forced to think about myself.

What exactly *is* ZFS doing when it takes forever to mount a dataset? I would think that most of the time-consuming work would be done at pool import, not mount time, but I have some filesystems that take minutes to mount after boot. #openzfs #freebsd

To summarize: I have a mirrored #ZFS pool which crashes both FreeBSD kernel and #OpenZFS when trying to import (both disks and each separately).

The disks are old but fine, no IO errors (I have dd/raw images of both disks), last daily scrubs were fine.

Ideas anyone? @robn perhaps?

That said, I would like your financial help:

Cleaning up the #OpenZFS Wiki

Improving the OpenZFS Test Suite

Building a lightweight #FreeBSD storage and virtualization platform that is well-documented and has no strings attached

ZFS encrypted root on Ubuntu 25.10, installed from a fresh USB key works fine following the instructions at

https://openzfs.github.io/openzfs-docs/Getting%20Started/Ubuntu/Ubuntu%2022.04%20Root%20on%20ZFS.html

It's a shame they dropped native support from the installer. That was a lot of hoops to jump through.

One thing missing was needing to run

addgroup --system gnome-initial-setup

otherwise gdm3 wasn't coming up. I'm also not sure if swap is working properly, but that doesn't really matter for me.
