Fake RAID install failure

English Install/Boot/Login

Trying to install 12.3 as downloaded two days ago. dmraid - NVIDIA chipset, install will not format partitions I am hitting this same bug:

[Bug 812316] New: openSUSE 12.3 will not install on dmraid RAID configur](http://lists.opensuse.org/opensuse-bugs/2013-03/msg04962.html)

I’m willing to go to a hardware raid solution if someone can recommend something that I can plug into the computer, attach my four drives (RAID10) and “go” – without having to send emails to the card company begging for driver support or searching endlessly for same.

Does anyone have a recommendation of a card that is a safe bet?

Well I hate to recommend hardware I have not used. In the past Promise was pretty good but some cards may be just FAKE RAID on a card. You have to be careful and maybe speak to a human before purchase. In any case if you get a card you will have to start from scratch since I doubt that formatting and metadata will sync to true hardware RAID. That is one of the troubles with RAID other then general specs the underlying tech is often not compatible.

thanks…that makes sense.

I’m downloading 12.2 right now since I do not believe this bug existed in that release; will try it…

here is a white paper from adaptec also good hardware in the past

wow, thanks for that - much appreciated :slight_smile:

Installing 12.2 right now, it is handling the NVIDIA rmraid with no problem at all. Too bad that bug got introduced in 12.3

I’m sure there is a bugzilla for this you should add you experience to it.

The squeaky wheel gets the grease :wink:

For RAID 10 I wouldn’t bother with a hardware RAID card. If you do have
to start again by formatting disks, you could just switch to mdadm
software RAID. It works with low overhead for mirroring & striping. It’s
only where there’s a lot of computation - RAID 5 or 6 - that you benefit
from a hardware board.

Th OP posted a link to the bug in his first post!

It looks like it attracted some attention, but then has stalled for some
reason that is not apparent. Somebody needs a poke up the proverbial!

Definitely add a ‘me too’ to that bug. Maybe it will wake people up to
actually fix it, or at least announce why it is stalled.

Looks like hacking the installer is the only workaround at the mo.

Having a similar problem - new mother board and I currently use a scsi raid 5 set up on 64bit PCI-X the lack of a raid 5 mode seems to be a decent indication of fake raids built into a mother board in particular. Also a statement such as windows only.

In my experience Linux has no problems working with any true raid card without specific drivers. Many also mention that they are linux compatible.

I here have the problem with raid0 on 2 ssd’s

so this is what id dit Install opensuse 12.2 because that is raid accepting and then with the dvd 12.3 upgrade your system and so bypass the faulty installer

but config you network in 12.2 because 12.3 is messing things up

every thing is working perfect this way.

have fun

Hm, have you ever used 3ware cards then? They work very well but use
3ware specific modules.
