So… I've got the before-mentioned WD product & I want to upgrade its inner storage from the existing 1 TB Green (WD10EARS) to 2 TB Green drive (WD20EARS).

I already managed to get a dump of the mybook.img file off the existing working 1 TB version. Using the dd command in System Rescue CD 5.0.0. distribution I managed to successfully unpack/clone everything to the WD20EARS drive.

So how do I expand that unallocated space after sda4 in order to make the OS "see" 2 TB of space & not the default 1 TB ?

In the console I tried running the command:

mdam --grow -size=max /dev/md2

And it didn't work.

So I tried issuing command:

mdadm --fail /dev/md2 /dev/sda4
mdadm --remove /dev/md2 /dev/sda4

Also didn't work, so I didn't even bother with the followup commands.

Any advice on how to solve this ? Do you need picture references ?


Scratch that!

Previously when I did this, it didn't work, but this time is has, using the Martin Hinner hack - as listed in the First Steps guide.

If anyone has any questions, fire away. :)


Hi all,

This is probably quite a long shot considering how old the bluering WD device is these days. However, I decided to put in a 2Tb drive - which I've done quite successfully. However, the issue came where, after I'd enabled SSH, I then updated the firmware from the basic version included in the recuse build to 02.00.18. Despite enabling the SSH client as per the instructions on this site in /etc/inetd.conf and /etc/inittab upon installation of the newer firmware, SSH is disabled, as it is post-reboot. So I'm stuck.

I've tried unsuccessfully to run through the various SSH enabling options to no avail. My only options seem to be to run through the whole process of rebuilding the disk and just ensuring I don't upgrade to the latest firmware. Frustrating!



I managed to find out why twonky is unstable, it should have been obvious it wasnt at the time.

Windows 10 server on the network causes twonky to crash even though I've havnt connected to twonky or the NAS. If I shutdown twonky prior to windows, NAS works fine.

and twonky starts up and stability is fine when windows is shutdown.

Anyone know why?

I went through a lot of these steps with frustration, but got it sorted in the end (copying data off now). Yes, the steps above to use a Ubuntu version are needed, the nice thing is that it's a lot more friendly than 5-6 years ago. You'll need to do some web searches to fill in some of the details, but the bottom line is that my NAS My Book World white light version (bought ~2013) had an XFS filesystem with RAID set (no idea why, only a single drive). But the RAID flag prevented the drive from being mounted.
Also, I tried using the rescue tool to rebuild the partitions, but that didn't work.
1. Remove drive and attach to your computer, steps listed in this blog.
2. Create a Ubuntu USB (I used Rufus after download to build the USB).
3. Log in and open a terminal window, do "sudo su" - will ask for your password, but put you in root.
3. Get gparted software (apt install gparted) - if it's already installed it will let you know. Also get mdadm (apt install mdadm) - not sure if this is needed.
4. Run to see partition, remove Raid flag.
5. In Terminal, mount drive:
mkdir /media/nas
chmod 777 /media/nas
mount -t xfs /dev/sdb4 /media/nas
6. Clear permissions on NAS drive:
cd /media/nas
chmod -R 777 *
7. You should now be able to see the drive in the file finder (mine was "997 GB Volume"). Lots of tips on the net for how to transfer files.

tvmobil free version allows streaming upto 10GB - thats not alot. I've already paid 2 licenses for twonky, one 4 years ago and one just recently as I couldnt find the 1st one.

Please, fresh installation instructions for twonky including removing the current broken version on the MBWE.

You should use tvmobili. It's great. I posted about manually installing it successfully here in the past. It comes with great instructions but be sure to use notepad++ to read them.

Hi Dav-M - Do you know where instructions exist to remove and clean install twonky on MBWE? I'm so frustrated, something has not quite worked and twonky eventually fails.

I want to have the latest version but following the instructions here has not worked for me.

I'm seriously considering another product.

Has anyone got this working for the twonky releases version 8.2 / 8.3 or the latest 8.4 release? I've tried with the upgrade notes but it either become unresponsive the first time or intermittently fails.

MBWE2 works fine for twonky versions up to v8.2.1.

That's a pity as v8.3 onwards has HEVC codec updates as well as samsung tv sub-title updates.

I've tried v8.3 and v8.4 and but it consistently overloads the NAS and eventually crashes.

Anyone who can somehow make it work with 8.4, I and so would many MBWE2 users would be extremely grateful!


Done the following:

/etc/init.d/S97twonkserver stop
rm -r /var/twonky/twonkyserver/*
rm -r /var/twonky/TwonkyServer/*

Followed post (…complete-guide-to-upgrade-to-twonky-7-8-version-my-book-worl) to install 7.0.8 version.
- points to note refers to 'Maxtor Shared Storage 2' software release

Goto IP address:9000 and enter license and its working.

I previously installed glrellm to provide realtime hardware statistics and the NAS is finally stable.

I'm looking at the various upgrade options as 8.4 is the latest release.

Its set to -1 and its been running for more than 5 years with any problems.

I plan to remove the full twonky installation and try again, I'll post the progress update later today

i set twonky to scan twice a day (660 min) and it's been running great! what's the longest amount of time you've had twonky stopped for whereby you didn't have an issue?

I dont believe it - its failed again!!

I've done the following to determine if its the WD NAS, my network or the NAS software (twonky):
As there were disconnection issues, IP conflicts could be an issue, so modem and switch restart. This is following reports of 'Connection to port 22: Broken pipe' and 'ping statistics of NAS with 20% packet loss'
NAS IP works fine but when twonky starts, IP disconnection intermittently occur..and therfore eventual loss of SSH connection. Also twonky DLNA service initially appears and then fails at the same time SSH loses connection.

I can only conclude its twonky…So why did it work for me ok this morning? and then eventually fail after 2 hours of non-use…?

I just reviewed the twonky rescan settings and the -1 (not all 9's i mentioned prior) is what used to crash my server a lot. I hear that you are using 90m so that should be better. If not, just increase it in the future.

So, after twonky 8.0.3 installation upgrade and new license applied.

Its all working, rescan interval default setting is at 90 minutes, I may change later.

Prior to the upgrade, i did clear the current db cache (rm * within the directory). It may that, the upgrade version created a new db cache and it never used the corrupted one.

The new version is much faster in terms of scanning, and its working fine.

Thanks for your help. While my mind is refreshed, I might be in the mood to further upgrade to 8.1.2 and upgrade samba v3.

I may even buy compatible WD disks to upgrade from 1 to 4 TB.

it was set to -1.

Now that I know the problem is twonky, I've decided to go for the upgraded version 8.0.3. I've had version 7 which was a long time ago.

Unfortunately, I've missed placed my OEM license, so I've paid for a new one.

I'll try with the new version and see where that leads.

How often did you have twonky searching for new files? I think i had problems in the past when i set that number to 9's as that like an immediate search option.

Thanks for you message [dz2k] but it seems to be twonky service itself. It happens only when twonky service starts.

I've moved the twonky startup script and its working fine without it. The WD site is working fine and the NAS mirror is good.

Whenever I initiate the twonky service, I think the file rescan causes it to hang and causes an overload CPU/RAM and all other serives eventually fail including pinging its IP address.

I can only conclude twonky's db is corrupt.

How can I reinstall it? I followed this […upgrade-to-twonky-7-8-version-my-book-live..] on the initial twonky installation but I'm not sure how to delete the db and reinstall it without affecting its license (paid for it).
