brian-willoughby (and pranav.bhattarai): The original report text confirms that "The exit code is 0, so update- grub does not fail as a result." That matches my understanding (as someone who has done a lot of ZFS installs maintaining the upstream Root-on-ZFS HOWTO) that this is purely cosmetic.
If you're not actually running other operating systems, you can simply remove the os-prober package to make the errors go away. I'm not saying it shouldn't be fixed. But it's not actually breaking your systems, right? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848496 Title: [zfs-root] "device-mapper: reload ioctl on osprober-linux-sdaX failed: Device or resource busy" against devices owned by ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/1848496/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
