HELPP need to restore raid5 using Knoppix

post #1 of 39
Thread Starter 
My raid 5 server went down and I've been using Knoppix to try to recover the files but it keeps giving me an superblock not found error when I try to mount the drive. Can anyone point me to a really good link? Thanks

OK, now that's quite different. You need to provide all relevant details up-front if you expect a useful answer.

What you need to do is:

Remove all 4 drives from the NAS, connect them to a PC, and boot from a Fedora Live CD. (The Knoppix CD won't do, and neither will an Ubuntu live CD.) The array can then be accessed via the "NASRAID" entry on the Places menu.

If "NASRAID" doesn't show up in the Places menu, we can move on to manually recovering the array. Let me know what you find.

Sorry for the late response but it didn't work. I tried all of the manual commands that I could find online. There wasn't a "nasraid" option in fedora

I assume by this response that you gave up and no longer want assistance recovering your RAID array?

well I tried all of the mdadm commands and spent about 10 hours on it. Is there something I'm missing that I couldn't find online? I'm just not very used to linux commands sorry. I thought that I should just send it out to a company. Any other input would be great. Thanks

Well, you didn't post anything you did here, so now you're going to have to do it all over again and paste here if you want any help. :\\

So, pop your Fedora live CD back in. First thing to paste is the results of:

Code:
su -  # you need to be root
fdisk -l
cat /proc/mdstat
mdadm --examine /dev/sd[a-h]*
