Need help with software RAID

English Hardware
1

My computer got messed up sometime ago it was SLES 11.1 and something I downloaded upgraded to OpenSuse 11.1, don’t ask me how! I have no clue.
I have a 7TB RAID running in software on it that has data that I want to keep. I want to refresh the system by blowing the OS away and making it an OpenSUSE 11.3 machine and then bring the raid back in. Is this easily accomplished if I disconnect the RAID while I rebuild and then reattach all the RAID drives back afterward? If someone knows a good link or has the answer it would be much appreciated. It’s a RAID 5 and I do not have the resources to back it up (for those who want to scold me on useless opinions :wink: on data safety) so if it’s easy to re-import back in as a RAID 5 that’s what I am looking for.

Thanks,
Tom

Hi Tom,

is there a problem here or? Apart from disconnecting your drive array,
what you’ve described sounds fine. You start an installation, set up
your install partitions the way you want them, add a mount point for
your array, and you’re set.

Tom;
This may not be the type of information you are looking for if not sorry, this is where I learned about setting up the Raid0 setup I run. I realize this is a Mac sales site I am just directing you to the Raid Center for the information as there is a lot of good info on many different raid setups. Not sure if it is what you need but I wanted to offer what I know.

So all I do is wipe out my current OpenSuse reattach the drives from the previous RAID after I install OpenSuse 11.3 bring up the machine and it will know there was a RAID on those drives and read it back into the system once it sees them? and then I just recreate a mount point for MD0 and away I go?? That’s it??

Just curious,
Tom

Assumption: your boot drive is not part of the RAID. You won’t need to
disconnect the existing RAID drives; YaST will see them, and you can
assign a mount point etc.
