upgrade - raid data drive issues

Hello,
The last few times I’ve tried to upgrade (11.2 to 11.3, 11.3 to 11.4 and now 11.4 to 12.1) raid fails.
I have a mirrored data drive using software raid.

So, if I try to upgrade, either from DVD or through the web via repos it all goes well, I reboot and it fails as being unable to start the raid. The last couple of times I ended up doing a fresh install and it detects the raid and works fine. I’d rather not fresh install, though.
So, question 1 is, am I missing something? Are the prerequisite steps I need to complete first?

And question 2 is, this is just a data drive and Ive noticed if I simply unplug the drives for hardware maintenance or something, it fails to boot if it can’t start the raid. Is there any way to make the raid a lower priority so that the system will start even if there is a raid failure? It’s just data… the system does not need it.

Thanks for your help.

i do not know, but maybe you missed logging a bug when you had this
problem when moving from 11.2 to 11.3, and then again moving from 11.3
to 11.4?

these things don’t get fixed if they don’t get on the bug list, here:

there is a supported and recommended method of upgrade here:
http://tinyurl.com/6kvoflv which has steps to take prior to the
upgrade…i just took a cursory glance and didn’t see where RAID is
directly addressed (maybe it should be, and maybe that is the outcome of
the bug suggested above…i don’t know)…but i do see something about
“Persistent Device Names” /etc/fstab, i have no idea if that would
impact your install…(i avoid RAID like the plague)

> And question 2

sorry, i can’t help that at all…

Well, I doubt it’s a bug, as I’m sure there are plenty of people out there w/ mirrored data drives… I’ve never had a system w/out a redundant data drive (win, linux, whatever) Maybe, though.

I did a lot of reading and followed the general update instructions, so I definitely need raid specific help. I removed all lines having to do w/ the raid drives from fstab, I disabled mdraid in the services list in yast… still fails on raid at startup. (unable to start mdadm)

So, if anyone else has any ideas… either how to get raid to upgrade properly, or even better I suppose, would be if you could tell me how to get the system to boot even if there’s a raid failure, I’d appreciate it. As I said, the raid is just an extra data drive and there are no system or home files on it.

interesting: it doesn’t work but there is no bug needing to be fixed…

i hope someone can help you…these forums are users voluntarily helping
other users…if you think you need to interact with the developers you
can find them IRC or the mail list…get to them this way:

Hi,
I’ve done a fresh install, RAID1 did work like magic…

First I removed the power cable from the RAID HDDs, then I did the fresh install of 12.1 on my SSD.
Later i reconnected the power cables to the HHDs, booted up and the RAID setup was automagical self-configured, I think openSUSE 12.1 read the Superblock and voila, RAID was configured.

The RAID was running in openSUSE 11.3 before.

Edit:
Oh, sorry, know I see that RAID was working for you also with a fresh install…

Man, if you don’t have an answer, don’t post! I really highly doubt it’s a bug… I’d be willing to bet I am doing something wrong. There have got to be a lot of people out there running raids, and I don’t see a lot of posts w/ problems when upgrading… So again, I don’t think I need to communicate w/ the developers, and just need to wait for someone else running raid to respond. I may need to go to a different area of the forum, other than install though, as now my main concern is simply how to have the system start w/ a failed raid. You already said you avoid raid, so please, stop posting to a question where I need answers about something you know nothing about.

Thomas, thanks and yeah, like you said it works like magic on a fresh install. I was very impressed at the ease of simply plugging in raid drives from a foreign system, and having them detect and work w/out intervention.

Well, I asked in the hardware section and got a reply about how to boot w/ a failed raid… which was to add “nofail” to my fstab.
I suppose I’ll try another upgrade now, and even if the raid fails, hopefully I can boot and fix it.
