[Bug 1874304] Re: grub-probe fails with failed to get canonical path of rpool with ZFS
I found a way to fix it:
$ sudo zpool status rpool -v
or
$ ZPOOL_VDEV_NAME_PATH=1 zpool status
Then you copy the drive path under the "rpool" section
$ sudo zpool clear rpool /dev/disk/by-partuuid/{disk-partuuid}
In your case it should be:
$ sudo zpool clear rpool /dev/disk/by-
partuuid/7b079781-02d8-b74f-a11f-4171bcb642d1

[Bug 1874304] Re: grub-probe fails with failed to get canonical path of rpool with ZFS
I'm unfortunately not going to be able to repair the pool. Since grub- mkconfig was blocking all apt package installation, I simply added "exit 0" to the top of the script to get things working. But, this was a bad time to discover my backups weren't working. That's my fault for not verifying them. I used to have a manually created ZFS root using the ZoL documentation and replicated that back to a FreeNAS system (FreeBSD 11.3). This time I let Ubuntu create the root and apparently it added feature flags that FreeBSD doesn't so my replication system ceased working. So, it's looking like I'm just going to have to recreate the pool. I leave it up to you as to whether you want to close this issue out. I do think it'd be nice if a grub-mkconfig failing didn't get apt into a state where nothing can be added or removed until grub-mkconfig successfully runs. It may very well be the case that fixing the pool requires fetching another software package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874304 Title: grub-probe fails with failed to get canonical path of rpool with ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zsys/+bug/1874304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1874304] Re: grub-probe fails with failed to get canonical path of rpool with ZFS
Thanks for the logs The error happens in grub-mkconfig. So much earlier than any zfs specific grub script. One of the main issue on your system that could lead to this error is the corrupted rpool. NAME STATE READ WRITE CKSUM rpoolDEGRADED 0 0 0 nvme0n1p4 DEGRADED 0 032 too many errors You should start by fixing it and see if it fixes the problem. Then bpool is not mounted. There is something that does automated snapshots which duplicate the automated snapshot feature of zsys. docker + zfs creates a lot of dataset which may lead to timeouts in zsys. Please start by fixing rpool and see if it improves the situation. ** Changed in: zsys (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874304 Title: grub-probe fails with failed to get canonical path of rpool with ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zsys/+bug/1874304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Tags added: apport-collected focal
** Description changed:
I've been running Ubuntu 20.04 daily builds for about a month. Within
the past several days, something broke with grub where it is no longer
able to probe my ZFS datasets in order to build up its menu. This had
been working fine, aside from the issue #1867007 I previously filed, so
I believe this is a regression. As a result of it, I'm unable to update
my kernel.
I noticed it when trying to perform a dist-upgrade, but it's
reproducible running `grub-update` on its own:
❯ sudo update-grub
[sudo] password for nirvdrum:
/usr/sbin/grub-probe: error: failed to get canonical path of
`rpool/ROOT/ubuntu_bp7ow2'.
❯ zsysctl list
IDZSys Last Used
-- -
rpool/ROOT/ubuntu_bp7ow2 true current
I realize that's not much information to go off of. Please let me know what
other diagnostic information you would need.

[Bug 1874304] Re: grub-probe fails with failed to get canonical path of rpool with ZFS
Hey, It’s a little bit hard to debug as you opened the bug without using ubuntu-bug tools which collects a lot of information (you can run apport-collect to attach more of them). Some tracks of though to get this going: - do you mind checking that zfs-initramfs and zfsutils-linux are both installed? - in general, can you list all zfs packages states? (dpkg -l *zfs*) This error is mostly grub not being able to load the zfs module (wed should probably fail earlier than letting grub itself failing). However, you do have the module loaded as zsysctl is returning you something, which is puzzling… -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874304 Title: grub-probe fails with failed to get canonical path of rpool with ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1874304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
