Re: [opensuse] RAID1 boot problems
Did you ever get an answer? If not let me know and I'll pickup the thread. But if you got it solved -- no need.
stop sending private mails. this is exactly what you are asking me if anyone else was intelligent enough to answer a question in private that was started in public. :( and no, i have not worked it out with grub, i have found a number of threads and discussions and hits (they talk about going to rescue mode with opensuse install media, selecting rescue mode, and doing the grub commands and various stuff there) but that all didnt work out and i didnt have the time to do some bugreporting yet. but i think i remember seeing some bugreport about grub that was talking about exactly this behaviour. will need to look up the links again. http://advosys.ca/viewpoints/2007/04/setting-up-software-raid-in-ubuntu-serv... i have also found some additional info about the pre-chroot remount stuff of /proc and /dev and stuff like that, that helped a little but the re-installing of grub on the two harddisks i have didnt succeed i still get errors and lots of complications inside the opensuse rescue system.... i dont recall the exact errors any more, it annoyed me really much, but its still unsolved. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The only solution to this will be to simply dig in and learn how grub works. True, sometimes some aspects of things aren't clearly stated in the available documentation, but testing and experimenting fills in those gaps and clarifies the ambiguities. Then there will be no more mystery. You will know exactly why it doesn't work now and what to do to make it work. Probably there are actually several ways to make it work. But it always depends on the particular details unique to your system, your hardware, your desired partitioning, your desired formatting and selection of filesystems, etc... You have to: a) know what your own details all are. b) know how grub works. c) apply the rules of grub config files to your particular hardware & software details. Shortcuts don't exist except in the absolute most common and dead simple cases, and often not even then. Or, by paying someone who already has spent that time figuring it all out to do it for you. Yes this is just a way of saying rtfm. Well, I had to, and still have to almost every time I need to do anything. I can't even answer most of my own needs and questions without rtfm and some tedious systematic testing and breaking down the problem into pieces. IMO, it's not reasonable to expect to solve most problems any other way. -- Brian K.

i have dug around a bit and found: https://bugzilla.novell.com/show_bug.cgi?id=398356 marked as resolved after 11.0, but as i am using 11.1 this is still not fixed for me. i only have two partitions on each identical sata disk, first one SWAP, and second (rest of disk is simply / ) that creates md0 (swap) and md1 (/ ) never the less, grub only gets installed to the first (sda) disk, but never to the second (sdb). when i remove the sdb disk, the system boots up fine in raid1 degraded mode, when i remove the sda any only try booting the system with the sdb disk, the system never comes up as i have described before. so this bug never got fixed in the first place i think. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I Create a Grub Floppy for exactly this situation that can boot the raid normal, and also in degraded mode if one or the other disk dies. I set the bios to boot from the first HD and then the Floppy. I've been doing it this way since Suse 8.something. There are fairly lucid instructions on how to build a grub boot diskette somewhere on the web. As long as one of your mirrors are operational you will be able to get up and running. Should you have to do it this way? No. But its nice to have the option. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It is easy to install grub manually to sdb as well, through the grub command line. Check out http://www.linuxsa.org.au/mailing-list/2003-07/1270.html especially point 6.
