How to recover data usin Linux
Hello everybody,
I have a ReadyNas 104 with 3 x 3 TB HDD in RAID 5. My Problem is that the RN104 is nolonger working. I need to access the data on the HDD and don't have a clue how to do so.
I installed the 3 HDD on my PC and run Ubunto. With the help of Google I managed to mount the first partion of the HDD but it looks like all the data are stored on the 3 one. I don't know how to access this one.
Does anybody had already made this experience?
All the help is warmely appreciated.
Thanks
Steve

- What happened that led to your RN104 no longer working?
How full is the 4GB partition that you've mounted?
You would need to assemble the RAID using mdadm, then mount the btrfs volume.
Something like this should work (you may need to apt-get some packages such as mdadm and btrfs-progs first if they are not already on your system):
# mdadm --assemble --scan
# cat /proc/mdstat
# mount -t btrfs -o ro /dev/md127 /mnt
N.B. It's possible the data volume may be e.g. on /dev/md126. But looking at the output of cat /proc/mdstat you should be able to confirm which md device it is on. - Hi mdgm
Thanks for the quick reply. I had some prob with the electicity. Turn on RN the fuse went of. After he is dead.
MD127 looks fine but the status stays inactive. Getting a message like below
wrong fs type, bad option, bad superblock on /dev/md127,
Help, I have 1.4 TB of data to loose - I think the RAID5 is somehow corrupted. As I have 3 x 3TB in Raid this should give me a total of 6TB but in gparted I only can see 3TB also is cat/proc/mdstat showing that it is a raid1.
How, Why. I don t know - Ps
The 4 GB partition is using 765 MB - What is the output of cat /proc/mdstat ?
- Thank you so much. you saved my day. I found why it was not working. one of the hdd were connected to a sata port which was disabled. after switching it on your instructions fixed my problem.
Thank you so much.
