[Bug 1965566] [NEW] grub-install fails if ZFS root pool is in degraded state
Public bug reported:
I have a system with a root ZFS pool that's DEGRADED:
$ zpool status -v
pool: rpool
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.
see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-9P
config:
NAMESTATE READ WRITE CKSUM
rpool DEGRADED 0 0 0
sda1 DEGRADED 0 0 0 too many errors
errors: No known data errors
In this state, "grub-install" will fail:
grub-install: error: failed to get canonical path of `rpool/grub'.
If I apply the following patch, "grub-install" works properly:

Sorry, I didn't mean to post that yet. The QCOW2 image we're using is based on Ubuntu 18.04, and I can give any details about how we're generating it, and/or it's contents (ubuntu-minimal plus some minor configuration changes). I can gather the logs requested from "cloud-init collect-logs" if that'd help, but based on Serapheim's comment and the easy reproducer, maybe logs aren't necessary? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686338 Title: cloud-init fails if no network config is set To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1686338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
