mount HDD aus Raid Iaus Linux ReadyNAS RND4450
Hallo zusammen,
ich möchte von einen ReadyNAS RND4450 eine verbliebene Festplatte auslesen.
Die Platte wurde in einem Raid I genutzt.
Das Ziel, was ich habe ist, die Daten von der Festplatte zu sichern und auf das neue NAS zu kopieren. Wenn ich das richtig sehe, nutzt Netgear EXT3 (Linux) als Dateisystem. Wenn ich nun unter Linux Mint die Festplatte per USB anschließe, sehe ich sogar die Partitionen unter „Disk“, nur ich kann sie nicht mounten.
Hat jemand eine Idee woran das liegt und/oder welcher workaround hier möglich ist?
Viele Grüße
Steelwood

Hello all,
I would like to read a remaining hard disk from a ReadyNAS RND4450.
The disk was used in a Raid I.
The goal I have is to backup the data from the disk and copy it to the new NAS. If I see it correctly, Netgear uses EXT3 (Linux) as the file system. Now when I connect the hard drive via USB under Linux Mint, I even see the partitions under "Disk", only I can't mount them.
Does anyone have an idea what this is and/or what workaround is possible here?
Best regards
Steelwood

See http://jim-st.blogspot.com/2012/07/mouning-readynas-drives-on-x86-systems.html
Simple step by step guide to mounting Sparc-based ReadyNAS Drives in x86-based Linux:
In a terminal window:
- sudo su
- apt-get install fuseext2
- apt-get install lvm2
- modprobe fuse
- vgscan
- vgchange -ay c
- fuseext2 -o ro -o sync_read /dev/c/c /mnt
You can now see the mounted files in the /mnt directory
(NB: Without the “-o sync_read” option to fuseext2 I had problems with copying large files. It kept saying the source file wasn’t found. After adding this option everything worked fine).
This might not work on the second disk. Though I haven't used RAID-1 on my NV+, I have used it on my Duo (which has the same architecture). The second disk in the Duo is formatted oddly, I think because of the RAID acceleration hardware built into the Sparc CPU.

Better use a correct data access on the operational NAS, export the volume e.g. in NFS, and mount accordingly over the network. Any kind of data recovery is never great idea.
Redynas OS 6 does indeed not make use of a LVM, however the file system is BTRFS.
