Recovering Linux RAID Partition Data

carlosinfl · 09-22-2009, 09:37 AM

I found my old drive which was previously in a RAID 1 mirror. The machine and 2nd drive used for the mirror are no longer available so I would like to know if it's possible to boot from Live CD and recover the data that is on the Linux RAID partition? I used Ubuntu 9.04 to boot into a live environment and was able to see my S-ATA disk with the Linux RAID partition table however I have no idea if it's possible to mount and copy the data straight off the disk. I need many important files that I believe to be on the partition table.

Can anyone please help me?

create a directory, then mount this disk to the directory.
from here you should be able to see the data and copy/move as normal.

No, I get the following error:

Code:

root@ubuntu:~# fdisk -l

Maybe if 'mdadm --verbose --examine --scan /dev/sda' returns something of use you could build a degraded RAID1?
