[Kernel-packages] [Bug 2051999] Re: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.
I've had two systems taken down by what seems to be this bug now in the last few weeks. This, together with the mismatched kernel and userspace version of the ZFS tooling is really, really bad. I do get that a ZFS root and the HWE kernel together is a rather esoteric setup but it's all out-of-the-box available to setup from the installer and repos. At this point any roll out of the 6.5 kernel should not be offered to users with a ZFS root and some sort of official documentation for how to recover should probably be posted somewhere. -- 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.

In the next few days, when I get some "spare" time... I will spin up a few test Jammy VM's to capture what depends it has to pull in from other repo's, so that the depends can be ID'ed and maybe those packages can be added to that Jammy package in this new PPA. Otherwise, as I just found out with a User, it put him into broken packages depends hell. Doing that while possibly bringing in those depends would simplify that... as just add the PPA and go with it. -- 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.

Update: Instead of my name space, I have uploaded a 2.12 version to this PPA: https://launchpad.net/~ubuntu-uefi-team/+archive/ubuntu/backports- build If it builds correctly, it can be used on Jammy with less fear by adding: "deb [trusted=yes] https://ppa.launchpadcontent.net/ubuntu-uefi-team/backports-build/ubuntu/ jammy main" The caveat of this being non-validated development software, and it not being compatible with Secure Boot are still there, but at least it should avoid the shlibs breakage.

[Kernel-packages] [Bug 2051999] Re: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.
1. Doing 2.12 backports to Jammy will happen, but it's not an overnight process. The delta from 2.06 to 2.12 is large, and even though it might work on your and my machine. We are hoping that the 2.12 release to Debian testing now, upload to Debian -backports later, and release to Noble in April will give us more time to see the effect in the field. Some minor breakage on old and odd machines will happen, I know that, as we have changed the entire kernel loading mechanism going from 2.12 -> 2.06, but hopefully it can be kept as minimal as possible. I am already in the process of integrating patches for issues reported in reaction to the Debian testing roll-out. 2. The PPA breaking Jammy has an additional very different reason to not doing 2.12 backports right now, it's because of the wrong build OS being used, basically: If you only install grub-efi-* from the PPA it's less likely to break, but the problem is `grub*-common` is linked against user-space shlibs from Noble which can and will be newer than Jammy's, and ABI backwards compatibility isn't exactly always a guarantee. The correct solution for Jammy would be to upload the same package with a slightly different version number and `jammy` as the series in d/changelog to a PPA, and then have "deb [trusted=yes] https://ppa.launchpadcontent.net/your_user_here/ppa_here/ubuntu/ jammy main" in sources. If you want a GRUB 2.12 build for Jammy right now, I can upload that to a PPA in my namespace. -- 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.

@mkukri --- >>> The question is, are we going to backport the fix to 2.06 and push that to the updates channel, or can this wait for the 2.12 SRU sometimes after April? >>> What does that mean? Option #1 -- The cherry picked Grub2 2.12 ZFS related commit code gets applied to Grub2 2.06 as a patch? Option #2 -- After April, when Grub2 2.12 gets published and released as a "stable release update," that it also gets released to Jammy and Mantic? But you said it has the potential to break Jammy? I'm not seeing that in my tests yet, but I believe you. Here is how I see the logic of this, but it means nothing, as I am not in the decision process, but: For option 1, that would take time anyways, and the Noble April Release is less than 2 months. So option #2 would be about the same wait with a whole lot less work involved by everyone. *** Until then, I have three working work-arounds for this non-booting error: Work-around #1-- The above work-around, which you say may break some things. Work-around #2-- I do have another work-around, that involves booting from an Installer LiveUSB. Backing up the content of bpool to a created backup directory "somehwere" (size needed is less than 2GB), saving the old UUID that was used in the old dataset name to a file. I used another USB Flash drive. Destroy the old bpool pool. Create the new bpool with these explicit creation options: >>> zpool create \ -o ashift=12 \ -o autotrim=on \ -o cachefile=/etc/zfs/zpool.cache \ -o feature@async_destroy=enabled \ -o feature@empty_bpobj=active \ -o feature@lz4_compress=active \ -o feature@multi_vdev_crash_dump=disabled \ -o feature@spacemap_histogram=active \ -o feature@enabled_txg=active \ -o feature@hole_birth=active \ -o feature@extensible_dataset=disabled \ -o feature@embedded_data=active \ -o feature@bookmarks=disabled \ -o feature@filesystem_limits=disabled \ -o feature@large_blocks=disabled \ -o feature@large_dnode=disabled \ -o feature@sha512=disabled \ -o feature@skein=disabled \ -o feature@edonr=disabled \ -o feature@userobj_accounting=disabled \ -o feature@encryption=disabled \ -o feature@project_quota=disabled \ -o feature@device_removal=disabled \ -o feature@obsolete_counts=disabled \ -o feature@zpool_checkpoint=disabled \ -o feature@spacemap_v2=disabled \ -o feature@allocation_classes=disabled \ -o feature@resilver_defer=disabled \ -o feature@bookmark_v2=disabled \ -o feature@redaction_bookmarks=disabled \ -o feature@redacted_datasets=disabled \ -o feature@bookmark_written=disabled \ -o feature@log_spacemap=disabled \ -o feature@livelist=disabled \ -o feature@device_rebuild=disabled \ -o feature@zstd_compress=disabled \ -o feature@draid=disabled \ -o feature@zilsaxattr=disabled \ -o feature@head_errlog=disabled \ -o feature@blake3=disabled \ -o feature@block_cloning=disabled \ -o feature@vdev_zaps_v2=disabled \ -o compatibility=grub2,ubuntu-22.04 \ -O devices=off \ -O acltype=posixacl \ -O xattr=sa \ -O compression=lz4 \ -O normalization=formD \ -O relatime=on \ -O canmount=off -O mountpoint=/boot -R /mnt\ bpool /dev/disk/by-id/ata-QEMU_HARDDISK_QM3-part3 >>> Set the UUID VAR from the old UIUID stored in the file, then recreate the bpool filesystem datasets >>> zfs create -o canmount=off -o mountpoint=none bpool/BOOT bpool/BOOT zfs create -o mountpoint=/boot bpool/BOOT/ubuntu_$UUID >>> rsync the old bpool contents back into the new bpool... Export the new bpool and reboot. Work-around #3-- Is to back up and reinstall, telling the user not to do any snapshots of bpool until this problem is resolved. Work-arounds #1 & #3 make no changes to the pool options. Work-around #3 has the risk of losing the user data. Work-around #2 is a whole lot of work, and has the highest risk factor of them all...

GRUB 2.12 isn't going into the updates channel anywhere at this point.

Wahoo! Found the magic combination. chrooted into the broken jammy system. Add a Noble sources list. Add the ppa.

Reconfigure Grub2 and update the initramfs images. Change the sources list back to the original jammy sources.list There were still existing snapshots there. Exit the chroot. Umount the mounts. Export the pools. Reboot. Booted fine. Fixed. Successful. Booting from Grub2 2.12. Writing up the work-around to fix it. I can post it on my ZFS -Fixes/Work-Arounds GitHub Repo. ...Or I can post it here. Maybe here is best. That way it is a known work-around for broken affected systems, until we can figure out the next step. The next step would be, how do we get Grub2 2.12 into Jammy through the updates channel? I would say it first needs to go to jammy proposed, then tested that it works through an update process. Then respin the installer ISO or include it in the next point release..

[Kernel-packages] [Bug 2051999] Re: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.
Since it is also built for Mantic, I would expect it works for Mantic Also. (Will confirm later.) I spun up a Jammy ZFS image. Changed the sources list to Noble. Added the PPA. Installed packages 'grub2 & shim'... Let it pull in the depends it needed. Change the sources.list back to jammy. Did some snapshots of bpool. Reconfigured grub, as it would do in an update... It said that was successful, so at that point was hopeful. Had fingers crossed. Rebooted, failed. Booted straight to BIOS. Shutdown > Cold boot > Failed. Booted straight to BIOS. So Grub2 2.12 works for the problems with Mantic and Noble, but not as a fix to Jammy 22.04. That sort of goes back to those last 4 patches (Grub2 related to ZFS) working to fix this problem for Noble & Mantic, but (somehow) need to be backported to fix Jammy.

[Kernel-packages] [Bug 2051999] Re: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.
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.

[Kernel-packages] [Bug 2051999] Re: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.
I'm working on trying various differing work-arounds with what is there natively. I tried building the newest git on Grub2 2.12. Fails building at a point which is says way fixed for the error i am getting, but still fails on the make at the same point. (asorti ot defined) I'm also working on another theory, recreating bpool with differing options, on the theory that on the creation of bpool, that some on the zpool options are causing Grub2 to fail with those added challenges. I'll keep you up-to date how those go. Trying to balance my time between "real life", helping the upstream Intel Graphics Support Engineers with drivers issues with Ubuntu, and helping Users with other issues. ...All while trying to find underlying information answers for this issue. What get's me, it that "feature" or "ability" that this is failing on, being able to snapshot bpool, because that is the failure point we need to protect from, was covered by Zsys, and why Canonical came up with that in the first place. It worked in 20.04 LTS... There was not a problem there, with that installed. We were able to do that in that release. Marketing-wise, it put Ubuntu ahead of things with that "need" covered well. Zsys was removed from being a default install (no mention why), but I still see commits to it. The need to make snapshots of the boot related files is still there. I wish I knew more on the why Zsys feel from favor. I thought basically,besides some minor changes, it was a great idea to do what it was intended to do. Some users, have gone around this problem by using ZFS Boot Menu (ZBM). But that is not a solution, Rather it removes the conditions, by what they have to do in the restructure to make it work. For it, bpool cannot exist. There cannot be a separate /boot. /boot has to be inside the root pool, and not inside it's own ZFS dataset... If this restructure is done this way, then those conditions do not exist. That is why is works. No that ZBM gets around the problem itself. If you crate a dataset for /boot itself, to make snapshots of boot related files, then ZBM does not work, even before the snapshots are made. It simply cannot find the boot related files, that way. (At all.) So to do a snapshot of boot related files, after that restructure, you end up having to snapshot the whole root pool, No, we need to find a way to get Grub2 and ZFS to play together nicely, and be stable. -- 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.
