Raid trouble

English Install/Boot/Login
1

Hello, I decided when I upgraded to opensuse I was going to impliment raid 5. Unfortunatly, my computer keeps freezing.
I don’t get any error messages because systemd does not print any to /dev/console (the computer just freezes), which, IMHO, is very bad show on it’s part, especially considering that it is so carefull to capture all messages on boot.
I can give you the journel though http://dpaste.com/0MBNCP8
And here’s the smart data http://dpaste.com/3P8Q31B
And I then ran a long test of the drive http://dpaste.com/30E9TVG
Thanks

The problem isn’t RAID, your problem is a fundamental “read disk”
According to your log, after your first read errors the system attempted to see if data could be retrieved through its RAID but that failed as well resulting in absolutely no ability to retrieve any disk data.

Since you didn’t post what came before the first disk read error, I wouldn’t know where in the boot process this occurred but most likely very early.

My other question is how many disks did you try to set up in your array.
You posted SMART results only for one drive.
If you tried to set up a RAID 5, you’d need at least 3 disks in your array.

You aren’t also clear what you mean by “upgrade”
Is this a brand new install?
Was there an earlier version of openSUSE on your system?
Are you multi-booting with any other systems?
You also need to clarify that this is software RAID (my guess) and not hardware RAID.

Yes, it did. I can’t give you the whole log as I tried to use an old opensuse 11.4 version to see if it was just the software.

  1. 3 disks.
  2. It only reported errors for the first, I’ll go get the resaults for the others…
  3. As in, I had opensuse 13.1 and I installed opensuse 13.2.
  4. Yes. To erase it I ran dd of=/dev/null if=/dev/sda (My memory of the exact commandline may be off, but you get the idea).
  5. No multiboot.
  6. Software, of course, created via yast and then I added the partition table and partition with gparted as yast did not have those options.

From what you describe, it sounds like you erased the drives (4). This means you are attempting a new install, not an upgrade. An upgrade means you are trying to preserve data, applications and settings from an existing installation in a new OS replacing your old.

YAST will provide you with options to configure RAID and various other options (like LVM), you only need to specify an “Expert Options” during the partition layout instead of accepting the default. Gparted and other outside utilities are not needed and may be incompatible with what the openSUSE install expects. You should do this(Use YAST advanced partitioning and schema), which should automatically apply current disk drivers (I’m wildly speculating you have a driver problem of some sort. Also, there may be different default methods for identifying disks and partitions with each distro version).

That’s my advice…
Instead of some custom homebrew using different technologies, try using options as presented only from within the one installation method which will use tested methods and technologies.

I started up the dvd and installed opensuse 13.2 onto a partition. I then tried to create a raid array but I got an error message indicating that the device /dev/sda as in use and so the array could not be created. I then rebooted and tried to crate the array for the dvd and got this error:


System error code was: -6008
/bin/ls -l --full-time '/dev/sda1' '/dev/sdb1' '/dev/sdc1'; /sbin/modprobe raid5; /sbin/mdadm --create '/dev/md0' --run --level=raid5 -e 1.0 --homehost=any -b internal --chunk=128 --parity=left-symmetric --raid-devices=3 ...
mdadm: super1.x cannot open '/dev/sda1': Device or resource busy.
mdadm: /dev/sda1 is not suitable for this array.
mdadm: super1.x cannot open '/dev/sdb1': Device or resource busy. 
mdadm: /dev/sdb1 is not suitable for this array.
...

The … were in the message, so that’s all I can give you. I looked at the system log but it had nothing about the disks in it. dmesg though, had some info which I’ve pasted to:

The output of a smart long test is here (one for each disk):

I think I figured out why the array is considered unsuitable, the partition is not set to fd for raid.
The opensuse install remains very unstable though. Even without the raid array. It crached 6 times in two hours.
Here’s the log:

Any help would be appreciated as I can’t have my computer continuously craching.

Thanks
