http://bugzilla.novell.com/show_bug.cgi?id=1080790 Bug ID: 1080790 Summary: EFI boot from software raid1 Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.3 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Documentation Assignee: fs@suse.com Reporter: jjletho67-esus@yahoo.it QA Contact: fs@suse.com Found By: --- Blocker: --- I think something is missing in the installation guide. The question is what is the best partition layout to have full boot and system redundancy with software raid1 and EFI boot mode? I did several tests and toughts (https://forums.opensuse.org/showthread.php/526269-EFI-boot-from-software-rai...) and i ended up in trying to manage two manually aligned efi partitions. This way looks promising but I discovered a blocking bug (https://bugzilla.novell.com/show_bug.cgi?id=1059169). While waiting for then resolution i discovered this in the SUSE "Storage Administration Guide" " For UEFI machines, you need to set up a dedicated /boot/efi partition. It needs to be VFAT-formatted, and may reside on the RAID 1 device to prevent booting problems in case the physical disk with /boot/efi fail " (https://www.suse.com/documentation/sles-12/stor_admin/data/sec_raidroot_requ...) In opensuse guides I have not found anything similar. I did a test and this configuration has worked fine for me! So if this is the official and supported way to have EFI partition redundancy in opensuse i think it should be documented, if this is not the way (and there are some doubts on it, especially when opensuse is not the only os installed, see my forum thread) the documentation should clearly say what is the best solution (and hopefully someone should think to solve the bug i mentioned before if that way the better one). -- You are receiving this mail because: You are on the CC list for the bug.
