I admit that I just found this with a Google search, but it sounds very much like the symptoms on your machine:

"When I run grub2-mkconfig the error: "ERROR: failed to lookup root id: Inappropriate ioctl for device" Happens right after "### BEGIN /etc/grub.d/80_suse_btrfs_snapshot ###"

I recently built a VM that had this error. I took a Leap 15.1 JEOS image and loaded it as a custom image into a Digital Ocean Droplet. It seemed to work fine and I did not notice if I had this error from the start. I recently upgraded the 15.1 to 15.2 and noticed the kernel was not being updated. The kernel was there, but grub wasn't being updated. Manually running the grub2-mkconfig command showed the same error: ERROR: failed to lookup root id: Inappropriate ioctl for device

I also recently noticed all of my snapshots have gone missing from /.snapshots and snapper reflects that.

Solution: the mountpoint for the @/.snapshots subvolume was missing from /etc/fstab. Correcting that solves the issue."

The JEOS image seems to not have snapper enabled by default, so I assumed this entry was not needed, it was not in the fstab. However, I tried the step mentioned here, added ./snapshots to fstab and now the grub2-mkconfig command works with no more ioctl errors, the grub.cfg file was updated with the new kernel entries and I could boot into the new kernel. -- You are receiving this mail because: You are on the CC list for the bug.
