pacman -Syu dmraid kernel panic!

kaizoku · 2010-08-20 08:04:11

Please help!

I ran a system upgrade today, everything went fine, rebooted. it caused kernel panic, then it killed my raid setup. now in nvidia raid tool, it says error. I am using fakeraid, lost about 2TB of data!!!

Since you choose to use fake raid over software raid, is it because you have a dual boot system?

I haven't used fake raid, and won't since I fear these scenarios, so I don't know if a System Rescue disk can recognize such a raid array. Doesn't the nvidia raid tool have the ability to fix errors with the array?

i can still mount it in boot cd but it refuses to construct the array when booting up, and yes i use fake raid to dual boot.

I found someone same problem, http://forums.fedoraforum.org/showthread.php?t=236404

It mentioned delete metadata dmraid -E

Will that kill my data?

Edit: Had to downgrade kernel, and it seems to create the array properly now. Perhaps this is a bug?

Back up your data, upgrade to the new kernel again, see if it breaks. Simple as that.

I have no where to backup 2TB of data.. even if I did, it would take forever.

I don't want to sound harsh, but if this is valuable data, and you have it on a RAID, with no means whatsoever to backup, then you should rethink your storage 'strategy'.

I have 3 TB storage in my server btw, and I regurarly back that up. The first backup does take a while, but after that it's all incremental. Either way, you don't have to sit around waiting till your backup finishes .

Isn't RAID meant to provide "redundancy" in the first place? And incremental backups wont work for me, I thought thats only good for programming stuff, because it changes and you can have versions.

So thankfully we're talking about a RAID 1 configuration here?

If it's not backed up, it's already gone ...

Backups and redundancy aren't synonyms. RAID is about availability, never about data security.

Incremental backups are good for anything that changes just a bit every day, like my personal docs. Instead of backing up my music collection every day, I have an additional 50KB of compressed txt files to back up.
