Hi all
I'm hoping this bug has already been fixed. I couldn't find any
reference to it online, thus my mail.
Whilst installing Archlinux onto a degraded btrfs (the second disk in a
"raid1" configuration was "missing" at the time), I found that
grub-mkconfig failed. The output was:
"/usr/sbin/grub-probe: error: could not find canonical path of ."
After a btrfs device delete/balance, grub-mkconfig succeeded without
issue. This is, admittedly, an unusual scenario.
In testing post-install I have been unable to reproduce the issue and
unfortunately I don't have another spare disk to test with. See attached
log where I attempted, unsuccessfully, to reproduce with loop devices.
Similar error message here two weeks ago

related.
