Title:
ZFS revert from grub menu not working.
Status in zfs-linux package in Ubuntu:
Fix Released
Status in zfs-linux source package in Focal:
Fix Released
Status in zfs-linux source package in Groovy:
Fix Released
Bug description:
[Impact]
* Users can’t revert to previous snapshots when enabling the hw enablement
stack kernel on focal or using any more recent version.
* The option is available on grub and will let you with a broken system,
partially cloned.
[Test Case]
* Boot on a system, using ZFS and ZSys.
* In grub, select "History" entry
* Select one of the "Revert" option: the system should boot after being
reverted with an older version.
[Where problems could occur]
* The code is in the initramfs, where the generated id suffix for all our
ZFS datasets was empty due to new coreutils/kernels.
* We replace dd with another way (more robust and simple) for generating
this ID.
-
@coreutils maintainers, any idea why dd is being flagged as having an
executable stack?
When I try to revert to a previous state from the grub menu, the boot
fails. The system drops me to a repair modus.
zfs-mount-generator fails with the message:
couldn't ensure boot: Mounted clone bootFS dataset created by initramfs
doesn't have a valid _suffix (at least .*_): \"rpool/ROOT/ubuntu_\"".
After a reboot I have an extra clone called "rpool/ROOT/ubuntu_", indeed
without a suffix.
After a little investigation I found the problem in
/usr/share/initramfs-tools/scripts/zfs at the end in function
uid()
{
dd if=/dev/urandom of=/dev/stdout bs=1 count=100 2>/dev/null | tr -dc
'a-z0-9' | cut -c-6
}, the dd command fails during boot with the message "process 'dd' started
with executable stack.
After this an empty uid is returned which explains the dataset without a
proper suffix.
Replacing the function with:
uid()
{
grep -a -m10 -E "\*" /dev/urandom 2>/dev/null | tr -dc 'a-z0-9' | cut -c-6
}
fixes the problem.

[Kernel-packages] [Bug 1959522] Re: 21.10 Impish ZFS revert snapshot via grub menu fails consistently
Just spun-up a couple of Gnome Boxes to test this. 21.10 fails as per my description whereas 20.04.03 LTS works fine. Just to be clear I am selecting to revert the snapshot at the top of the list each time (this is the snapshot taken just before neofetch is installed). Meanwhile my main laptop where I first experienced this problem no longer boots and so I am re-installing with the LTS, so for me this is a nasty issue. I do have another test machine and am happy to collect data if required but as I say this can easily be duplicated. Thanks Nick -- 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/1959522 Title: 21.10 Impish ZFS revert snapshot via grub menu fails consistently Status in zfs-linux package in Ubuntu: New Bug description: This issue seems similar to 1894329 but I can reproduce this consistently in 21.10. Problem description: Unable to reliably revert ZFS snapshots via the Grub menu in Ubuntu 21.10. When attempting a revert I am usually dropped to the emergency mode and have to force a reboot. After that it can take a number of attempts to get the system to reboot to the desktop. Steps to reproduce: Install Ubuntu 21.10 on Intel 64bit with ZFS selected as the filesystem. Do not encrypt. Install all updates. ZFS snapshot is taken automatically. Reboot. Install a simple package i.e. sudo apt install neofetch. Another ZFS snapshot is taken automatically. Reboot and enter the GRUB menu. Enter History menu. Select Revert to an earlier snapshot. In my case I select the snapshot taken before neofetch was installed. Select install system files only. Do not select the recovery mode option. System now boots and ends up dropping into emergency mode. I can duplicate this on three different installs. Expected outcome: The snapshot is correctly reverted and the system boots without user interaction into the snapshot.
