how to install LEAP on boo-table RAID-1?

ok, I have posted a question(s) earlier but it was too broad and left unanswered, so I will start my quest with this post first.

I am planning to rebuild my home server. been playing with different OS and openSuse looks good so I want to try it out again. my last interaction was with 13.1 some time 1.5+ years ago.

my first question is hot to properly install LEAP using MD RAID-1 for bootable system setup.
I mean I want to install OS using a raided system disk so if one disk fails the system would still boot and allow me to replace failed drive hot. with no downtime.
I know it workd with hardware raid, and I know it supposedly works with linux software raid but I could never make it work for me.
please can some one give me a step by step on disk layout and install process.

thanks.

I have been trying to install Leap on a marvel 88SE61xx without success. The system does not boot at all after upgrading from OpenSuSE 13.1.
I have an ASUS P5Q-E MB with 2x 2TB SATA 2 drives and nVidia GeForce 750 TI video adapter. The system is dual boot with Windows 7 and should boot Linux as a primary OS. No joy.
fresh installation on a single drive completes, but the graphical login fails.

I think you are mixing different cases (one about “not booting” and anothee one about “no graphic login”). And both without any details. This will probably assure that you again get no answer because people hate it to enter a mess and then have to ask for each and every detail.

Thus please concentrate on one of the problems first. And tell what you do, what you expected to happen and what happened. Saying someting like “trying to boot without success” can be anything, starting from the power on button not moving, via the BIOS giving bleeps and then nothing, to the system going ablaze. People here can not look over your shouldder. Most of them have apperently not your problem. Thus apart from visiting you in your home, they completely depend on what you explain.

Agreed, the two posts are about different kinds of RAID, the first one was about installing software RAID during a new install, and the second one is an upgrade on hardware RAID. Very, very different.

I doubt the OP is still monitoring this thread after his post going unanswered for 3 mths, but for the general community I doubt this should be too much of a mystery… Simply select Advance Options during setup and specify a different disk layout. You can select modifying the default layout (advisable if you have no prior openSUSE install experience at all) or creating your own layout from scratch (only for experienced Installers). You will be presented with a graphic Partitioner which allows you to inspect and configure recognized disks and volumes, including options specifying LVM, encryption and RAID.

But, since nowadays cheap RAID adapters are so available, I generally recommend the traditional “Use hardware RAID over software” always… The only benefit to software RAID is cost. If you ever run into a problem hardware RAID is infinitely easier to recover and re-build. Just don’t forget to buy an extra RAID adapter or know where to get a replacement if that fails.

If you see an error, you should inspect and if necessary post it for others to see. It should describe exactly what the problem is so we don’t have to guess.
As it is,

  • You might be failing on initial boot (Is there something wrong with the RAID which should be set up completely before data is read off the disks? Have you tried temporarily breaking the mirror and booting off one disk?)
  • If the mirror is fully set up and running but you don’t see a GRUB bootloader (or Windows bootloader, whichever chainloads first), then perhaps the boot files or partition can’t be located?
  • If a bootloader loads but does not then load an OS, then the OS files can’t be located.

Be aware (and it’s been mentioned plenty in these Forums) that whereas openSUSE 13.2 identified disks by a numerical ID, LEAP goes back to the traditional generic disk name (eg sda) notation. If the upgrade didn’t modify the disk id correctly, you may have to edit your /etc/fstab manually.

Also, if you have secure boot turned on and you don’t remove that, then you can’t install a new OS successfully.

Sorry, I did not notice this earlier, but it seems that you are hyjacking someone else’s thread. Your problem is most probably NOT exact the same as the one in the title from the OP. Thus you should not add your different experiences to this thread. That creates confusion. The more while your question will not show amongst the new problems, but is hidden in this thread.

Please start a new thread with a good title that will draw the attention of people that may be able to help you.

And of course make a good description of what you do and see.

Sorry, didn’t intend to hijack.
