Forgot to mention... Those "@feature" changes, that are suspected as being the problems when enabled... unfortunately cannot be done on an already created bpool. Those can only be set at pool "creation time".
So I'm working on a script to recreate bpool which those specific option settings from the existing bpool, offline from an installer LiveUSB, environment. If I try it from online, it will not export the bpool. It just says "busy". Using an additional USB flash drive to temporarily hold the backup from bpool to destroy and recreate the bpool. That is the path I'm investigating and testing currently. That currently is, in the absence of a Grub2 2.12 that works with those conditions. If the new Grub2 2.12 does work with the older option setting, then a lot of thigs will be resolved, and a work-around will not be needed to fix existing installs nor new options set in ubuntu-desktop-installer. I installed just Grub 2.12~rc1 to 22.04.3 with the associated long line of depends. It wasn't pretty. And it did not correct the problem. That was not an answer to recommend. But at this point in time, because of Grub 2.12 not building and is vaporware. We don't have enough here to test, and make informed decisions. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/2051999 Title: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.
