Just an FYI, this is still present in 16.04.4 which I just `apt-get upgrade`d to. I have /boot/EFI on a md RAID1 with 1.0 metadata.
I'm not sure whether the severity is correct; as far as I could tell when hacking about with the efibootmgr command, the process had removed the 'ubuntu' boot entry before failing to add the new entry, so I suspect my system was unbootable. I have now used efibootmgr to add a new boot entry, but I'm working remotely and I'm not going to attempt to reboot until I'm sitting in front of the machine with a rescue disc/stick to hand! In particular, I am not clear what level the efibootmgr command is operating at: when I did the add on /dev/sda, subsequently listing it suggested it was also present on /dev/sdb... and I'm not sure whether in fact I ought to have two separate boot entries, one for each disc, so that if sda is a bit screwed but still present, booting can proceed with sdb. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1466150 Title: grub-install breaks when ESP is on raid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1466150/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
