I'd like to share the procedure I used on Ubuntu 12.04 and ArchLinux to access data from a disk of a degraded RAID 1 created with a D-Link DNS-320L NAS.
The graphical way is really simple: you just need to
- install the mdadm package
(sudo apt-get install mdadm on Ubuntu and Debian, sudo pacman -S mdadm on Arch)
- restart the PC
- connect the disk via SATA or USB dock
- three partitions show up on the file manager: the biggest one is the partition that contains your data.
The command-line procedure is a little more complicated:
- install the mdadm package
(sudo apt-get install mdadm on Ubuntu and Debian, sudo pacman -S mdadm on Arch)
- connect the disk via SATA or USB dock
- run lsblk to find the partition that contains your data and write it down (e.g. sde2)
- use mdadm to assemble the RAID: sudo mdadm --assemble --run /dev/md0 /dev/[YOUR PARTITION]
- create a new mount directory for you disk: sudo mkdir /media/raiddisk
- mount you disk: sudo mount /dev/md0 /mnt/raiddisk
- now your data is accessible and mounted in /mnt/raiddisk
before removing your disk, remember to:
- unmount the disk: sudo umount /mnt/raiddisk
- unmount the RAID: sudo umount /dev/sd0
- stop the RAID: sudo mdadm -S /dev/md0
