Cause

I tried to install OpenVPN, and made a config error in server.conf, so after start of the "OpenVPN" service, I lost connection

Afterwards for every boot, the ReadyNAS got 2 IP Addresses and was non-responding on both - even though I could ping one (10.0.0.100) until OpenVPN Started...so I was pretty sure this was "just" a config issue.

In RAIDar, It looked like this:

Failed recovery Attempts

I tried OS Reinstall via the built-in function, but the problem was still there (which I find pretty wierd)

I tried USB Boot that keept on failing with "OS Index Error" on several USB Sticks.

 

The Solution

I googled and found http://onlyblueatwork.wordpress.com/2012/12/04/netgear-readynas-access-recovery/

I booted the ReadyNAS in "Tech Support" mode and used Telnet go enter:

Username: root

Passwordinfr8ntdebug

Now, there are 2 interesting things, 1 - the OS Partiton and 2 - The Data partition

1 - OS Partition

The googled article refers to "mdadm" - with was not on my NAS (Raidar 4.1.13), after a lot of trial-and-error, I got the raid started:

Kodeblok
# ./start_raid.sh
# cat /proc/xraid/configuration
VERSION/ID::superblock=(0.1.0),ID=7f255168.00000000.00000000.00000000,create_time=4f873c3e

RUN_PARAMETERS::raid_running=1,last_word=ok,interface_start_at=1,fake=0
RAID_REBUILD::sync=0,logical=0,parity=2,sectors=0,total=4294967295,source=7,total_drives=3,auto_sync=1

RAID_P_INIT::initialized_bitmap=0x7,initialize_error_bitmap=0x0,initializing_bitmap=0x0,current_sector=0,total_sector=0

The "mdconfig" binary on the ReadyNAS was not very verbose, but try to use "DMESG" for some output". The output above stated that the X-RAID is fine.

 

Here after, It should be poosible to mount the OS Partition as:

Kodeblok
# mkdir /mnt /mnt/root
# mount /dev/md0 /mnt/root

but that fails, so I did a (in the DMESG output I could determine the physical disks as /dev/hdc /dev/hde /dev/hdg):

Kodeblok
# mount /dev/hdc1 /mnt/root
# rm /mnt/root/etc/openvpn

I was a bit concerned about changing directly on /dev/hdc ...

After the simple removal of the OpenVPN Startup I did a reboot and - Ta Da - everything was ok again - Due to OS Reinstall I had lost some settings (backup settings was gone).
