Wow, opensuse raid issues on intel raid, os 11.3

English Install/Boot/Login
1

Okay!
Thanks for looking at my thread, and for any help you may have.

I have installed pensuse about 99 times in the last week.

My eyes are starting to hurt from seeing so many green lizards!

Okay, so here is my problem,

mdadm, runs during boot, but it seems there is a bug in 11.3,
mostly, no matter what you do in mdadm, it does save anywhere, even during installation of system.

answer::::

How do I get mdadm to run with the -A -scan during boot, before any sort of mounting goes on, becuase as soon as that happens and the raid isn’t compiled, the system goes int recovery console, and f, fffff, I am not a noob, I am no L33t haxzor, but WOW… this experience has made me relise how little I know about linux, and how much there is to know before you know even a little,

Thanks everyone in advance for loooking, being, and helping this forum, Open suse roxzorz, and youguys make it that way.

You don’t give any details of how your RAID is configured or how you set things up at installation.

I have successfully created and operated RAID-1 mirrors on openSUSE-11.3 right from initial installation.

Give us more information and perhaps we can help you get things running.

neat trick! put mdadm in /sbin, and then run it BEFORE /sbin’s
partition is mounted…

i don’t know how to do that and add the -A -scan switches…

when you installed openSUSE (which version by the way, and which
desktop environment, if any?) and when it got to the page in the
install script where you get to select the partitioning scheme and
file systems used on the various partitions, how did you set all that
up? did you go for LVM or what?

is this a laptop, desktop, rackmount server…what?

what kind of RAID are you using? hardware/software/firmware/fake what?

and what level: 0, 0+1, 1, 1+0, 2, 3, 4, 5, 5+1, 10, what?

and, by the way is this the same machine as in your other post
http://forums.opensuse.org/english/get-technical-help-here/hardware/453444-intel-raid-partition-dissapeared-after-install.html#post2284282
which mentions you selected NTFS as the file system on that machine?

we need a lot more understanding of your problem if we are gonna find
a way to help you.

It’s not that hard.

If you mark your RAID component partitons as type Linux RAID Autodetect the kernel will load the appropriate modules and start the RAID array at boot, during device discovery, from the initrd - before any file systems are mounted.

mdadm isn’t required to start the array and, on my systems, only runs as a daemon process to monitor the state of the array.

It is ext4 raid 0 10terabyte
I have tried every possible config threw setup, no matter what you do, the raid wont be set to start after.

I am manually starting the raid after boot at this point…
I am using 11.3 and kde.
How do you mark the partition linux raaid autodetect?

The installer allows you to edit the partition parameters (either when creating them or afterwards before the packages are installed).

Choose Linux RAID or similar filesystem type (I am working from memory here) for your component partitions e.g. /dev/sda1, /dev/sdb1 then create your RAID device e.g. /dev/md0 (using /dev/sda1 and /dev/sdb1) giving it the ext4 filesystem type.
