NIC Died on NV+ HELP retrieve files with Linux!
My NV+ can't be accessed due to a surge shorting out it's NIC. The data and the drives themselves seems fine, and booting the NAS just tells me the NIC failed. Its out of warranty so I read up on and hooked up my 4 drives to Linux box and followed this guide http://home.bott.ca/webserver/?p=306 . Specifically:
In a terminal window:
(1) sudo su
(2) apt-get install fuseext2
(3) apt-get install lvm2
(4) modprobe fuse
(5) vgscan
(6) vgchange -ay c
(7) fuseext2 -o ro -o sync_read /dev/c/c /mnt
All went fine till here, c volume was detected (2.9 TB .Ext3) and can be seen in the Disks utility under other devices. But I can't access/see the files!
Going to the /mnt dir gives me an icon with code on it and that I can't access and trying to mount the volume from the Disks utility gives me an error:
Please, I'm stuck and I've gotten as far as I can with Linux.

- Error mounting /dev/dm-1 at /media/demitri/c: Command-line `mount -t "ext3" -o "uhelper=udisks2,nodev,nosuid" "/dev/dm-1" "/media/demitri/c"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/mapper/c-c,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
(udisks-error-quark, 0)
Please, I'm stuck and I've gotten as far as I can with Linux.

- Please, isn't there anyone that can point me in the right direction???
- what linux distribution are you running on PC? do you try
(8) cd /mnt
(9) ls ? - I'm running Ubuntu 13.10. Yeah, I try to access /mnt from the command line but it says i don't have permission. Placing the disks back in the NAS shows everything is fine (minus the dead NIC).
Using the GUI back on Ubuntu though gives me the error in my first post when I try and access /mnt or open the EXT3 volume from the Disks utility. No errors either when mounting the raid, just when I access it :( - strange, I tired 1 disk from my duo and put it on my ubuntu 13.10 by USB dock, it works.

any warning or error show up when you run the following?
(1) sudo su
(2) apt-get install fuseext2
(3) apt-get install lvm2
(4) modprobe fuse
(5) vgscan
(6) vgchange -ay c
(7) fuseext2 -o ro -o sync_read /dev/c/c /mnt
(8）cd /mnt
(9) ls - maybe also run "dmesg" , see if kernel complain something.
- I had to be root to go to the /mnt partition without the permission complaint.
