Please go back and read the original description of this bug. The scenario you describe is completely different than the bug that James Troup reported in March of 2006, which has been fixed.

Colin- I have a proposed patch in a bzr branch of grub: * https://code.launchpad.net/~kirkland/grub/33649 The first patch handled grub-installer used in the debian-installer, and this one handles grub-install (in the grub package), used in the installed operating system thereafter.

If you really desire SMART disk scanning in the initramfs, please open a new wishlist bug against initramfs-tools and capture these requests there. smartctl cannot necessarily be used on all devices in an array. It does not work on all drives. It will not work on USB connected media, flash disks, or other increasingly popular alternatives to traditional IDE/SCSI disks. And in my experience, it has yielded both false positives, and false negatives. I think that SMART is more trouble than it's worth *in the initramfs*. Please use SMART until your heart is content in runtime. Run it in a cronjob, using smartctl+mdadm and email yourself the results, if you want. b) Did I misunderstand when assuming that kernel boot paramters must be set beforhand (when grub is running) or how will the user interface look. Kernel boot parameters can be statically set in the grub menu.lst, or dynamically in the grub boot menu. The boot process needs to be as automatic as possible.

@Dustin My intention is to fix this multi-faceted bug in an incremental and solvable manner. My suggestions ARE along these lines :D That the bug has been around for 2.5 years is a testament to the fact that it is difficult to solve. Breaking it down into manageable bits is a tried and true software development process. No, not only me had found workarounds for booting in urgent cases ... That in Ubuntu it is still present has other roots... Did anybody object to your tried and true development process?

@Dustin: Do I err with my impression that your intension is to get some quick fix while my concern is to make Ubuntu as simple and reliable as possible? It is now the moment to make sure that the user interface while booting mirrored raids is understandable and maneagable not only for experts but also for ordinary people like me ;-) a) I am not fluent enough in bashing, so I can give only some hints easily realiziable for willing experts: (btw smartctl adds 176K to 8M of initrd and imho is worth the effort). Do for all devices used in array: smartctl --smart=on --offlineauto=on --saveauto=on -H /dev/sda if [ $? != 0 ] ; then echo smartctl error $? in /dev/sda ... b) Did I misunderstand when assuming that kernel boot paramters must be set beforhand (when grub is running) or how will the user interface look.

(btw smartctl adds 176K to 8M of initrd and imho is worth the effort). Do for all devices used in array: Firstly, this is off-topic for the current bug against grub. If you really desire SMART disk scanning in the initramfs, please open a new wishlist bug against initramfs-tools and capture these requests there. smartctl cannot necessarily be used on all devices in an array. It does not work on all drives. It will not work on USB connected media, flash disks, or other increasingly popular alternatives to traditional IDE/SCSI disks. And in my experience, it has yielded both false positives, and false negatives. I think that SMART is more trouble than it's worth *in the initramfs*. Please use SMART until your heart is content in runtime. Run it in a cronjob, using smartctl+mdadm and email yourself the results, if you want. b) Did I misunderstand when assuming that kernel boot paramters must be set beforhand (when grub is running) or how will the user interface look. Kernel boot parameters can be statically set in the grub menu.lst, or dynamically in the grub boot menu. The boot process needs to be as automatic as possible. Asking questions detracts from the ability to perform unattended boots. :-Dustin -- root raid installs have bad grub config https://bugs.launchpad.net/bugs/33649 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 33649] Re: root raid installs have bad grub config
@Dustin My intention is to fix this multi-faceted bug in an incremental and solvable manner. My suggestions ARE along these lines :D That the bug has been around for 2.5 years is a testament to the fact that it is difficult to solve. Breaking it down into manageable bits is a tried and true software development process. No, not only me had found workarounds for booting in urgent cases ... That in Ubuntu it is still present has other roots... Did anybody object to your tried and true development process? You as a bright expert might deny like some of your very bright collegues that sometimes non experts can give hints for better ui design. a) I am not fluent enough in bashing, so I can give only some hints easily realiziable for willing experts: I understand. My asking for a patch is a polite way of saying that while you or others might be willing/interested in implementing the functionality, I do not think it to be a productive use of my time. Well, after having spent some time to find out how the patch you requested could be realized, II won't publicly tell you what I think of your so called politeness. However, I'm not entirely closed off to the idea (should someone else do a good job with it), and I'll gladly review the code and offer constructive criticism. After all, I won't give any further comments on your attitude. PS: And your explanation has shown that I was not too wrong when assuming a few messages above that users will have to fiddle around with grub... :( This was my very last comment on the subject.

[Bug 33649] Re: root raid installs have bad grub config
I think I just saw this problem when I installed gutsy from the alternate cd. I have an existing RAID5 array on /dev/hd[cegi] and /dev/[cbef] which is /dev/md2, and installed to /dev/sd[ab]1, with swap on /dev/sd[ab]5. The installation went pretty much as expected (considering I had a previous FC6 RAID1 installation on there), but the reboot failed. To make it work, I had to edit boot from hd(4,0) to hd(0,0). That this works has me confused since the /boot/grub/device.map has /dev/sdb as hd(4,0), so hd(4,0) is the correct device and should work. -- root raid installs have bad grub config https://bugs.launchpad.net/bugs/33649 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
