Wrong. I think it used to be so (8.0), but I have an md root and home similar to the OP with NO separate boot partition. I do think grub has to be installed in the MBR though, as was suggested.
I finally got around to trying this. During install, when I create a logical volume on RAID for /boot, I get the error message: 'You cannot use the mount point "/boot" for LVM.'
LVM I would agree. A separate /boot where grub can locate its files are required.
If I try without a separate /boot LVM, I get the error message: 'Warning: With your current setup, your OpenSUSE 10.2 installation will encounter problems when booting, because you have no "boot" partition and your "root" partition is an LVM logical volume. This does not work.'
Again, with LVM it makes sense.
So it appears I'm correct. You need a boot partition outside of LVM & RAID, at least with LVM on RAID.
Correct.
When I create a separate RAID array for /boot, I get the error message: 'Warning: With your current setup, you OpenSUSE 10.2 installation might not be directly bootable, because your files below "/boot" are on a software RAID device. The boot loader setup sometimes fails in this configuration.'
That is when IIUC you install grub loader to something besides the MBR. If GRUB stage 1 is installed in the MBR, it works fine (though finds its files on one of the disks). It even, since it is a RAID 1, works with a fallback to the second disk in case the first disk failed.
Then, if I click on "Accept", I go back to the "Installation Settings" screen, where under "Booting", I get the message: "Because of the partitioning, the bootloader cannot be installed properly."
So, once again, with software RAID, with or without LVM, /boot cannot be on a RAID array. I'm glad my system does not have artificial intelligence and know what you said. It might decide it cannot work as it is now and cause me
BTW, did you set, in Yast, System, etc/sysconfig Editor, System, Bootloader, LOADER_LOCATION to mbr? problems. I boot from a system with software raid 1 / with /boot on it every day, with 10.2 (though it has worked since at least 9.3). I will say I have had problems with Yast with 10.1 and got used to installing grub manually every time there was a kernel update. 10.2 just works correctly (i.e grub should not be messed with at all with a kernel update). So it does boot with /boot on a software raid 1, WITH the caveat grub stage 1 needs to be installed in the mbr. -- Joe Morris Registered Linux user 231871 running openSUSE 10.2 x86_64 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
