I can confirm that Overlay / Rootoverly isn't working anymore on my TP Link 1043ND ;(

That's weird... When I add a slash at the end of overlay, it's mounted during boot.

config 'mount'
        option  target  '/overlay/'
        option  uuid    '4c4f67d0-c6a1-43d9-b857-5da952c7eef1'
        option  enabled '1'

Here is my df -h

root@OpenWrt:~# df -h
Filesystem                Size      Used Available Use% Mounted on

/dev/sda1                 6.9G     31.1M      6.5G   0% /overlay

But the packages are not installed on the new overlay /dev/sda1. They are still installed on /dev/mtdblock3 which will be out of space soon. Can anyone help please?

Settings that work for me
etc/opkg.conf

src/gz barrier_breaker http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay

What in your /etc/config/fstab

Mine doesn't have back-slash at the end.

No, it is a standard slash I put. Not a back-slash. But this didn't work anyway. It creates just another mount point with /overlay name, the new packages still goes to /dev/mtdblock3 --> /overlay.

config 'global'

        option  anon_mount      '0'

Mine MR3420 also cant mount overlay
if i

config 'mount'
        option  target  '/'

it wont detect the ext space

Extroot problem continues, neither pivot overlay nor pivot root works. I wish there is an Attitude Adjustment for my router.

@isiku: try http://ecco.selfip.net/attitude_adjustm … pgrade.bin

@obsy, I've spent all my weekend for this without any success. But today, you've made my day... Thank you!

Oh, good. Have you compile it yourself?
May I have a look at /proc/cpuinfo just for knowledge?

No, I didn't compile, @obsy did (I guess). Here goes /proc/cpuinfo

Hi, this thread always comes up when you google fstab new openwrt and wanted to let you know how I fixed it.

1. Compile the latest trunk with
block-mount
kmod-fs-ext4
kmod-usb-ohci
kmod-usb-storage

To find where these are in the menuconfig type / and you can search for them.

2. Upgrade the system: sysupgrade -v /path/to/file/openwrt.router-sysupgrade.bin

3. Run block info and find out what /dev/sdx is your usb
Then run:
mkfs.ext4 /dev/sda1 (you will need to install e2fsprogs for this)
mount /dev/sda1 /mnt
mkdir /tmp/cproot
mount --bind / /tmp/cproot
tar -C /tmp/cproot -cvf - . | tar -C /mnt -xvf -
sync ; umount /mnt
umount /tmp/cproot

4. After this run:
block detect > /etc/config/fstab
nano /etc/config/fstab (install nano if you dont have it or use vi /etc/config/fstab)
and modify the target line and option enabled line so that it looks like this:
config 'global'
        option  anon_swap       '0'
        option  anon_mount      '0'
        option  auto_swap       '1'
        option  auto_mount      '1'
        option  delay_root      '0'
        option  check_fs        '0'

config 'mount'
        option  target  '/'
        option  uuid    '7d3abfaf-493a-46bb-9730-1d793ecb9783'
        option  enabled '1'

config 'swap'
        option  uuid    '76d36596-5710-4b77-a3a7-02a66d469750'
        option  enabled '1'

5. Reboot

6. Here's proof that it works

If someone could add this to the wiki in a Barrier Breaker section at the top that would be great.

new kernel 3.10, tutorial from shape, tplink wr703n still not working / nor /overlay

please someone with tplink wr703n that is working? or which hardware is ubox working?

the bug is probably only with memory card if i use m2 memory card / or /overlay dont work
the card is detected in mount block as /dev/sda (dummy partition)  and real partition /dev/sda1

with usb flash working without problem tested / and /overlay

bug: if memory card is detect with dummy partition for example /dev/sda

I can confirm that's not working on TP Link 1043ND, Looks so that all AR71xx Based Routers are broken.

is there somebody who success extroot with the new ubox?
I failed.

Works for me. (TP-Link WDR3500). Read 3rd post above yours for a full tutorial. Also several other people on IRC confirmed that it worked for them as well.

I think it should work, you should use uuid.

Hello, everyone! Check out the new section (Barrier Breaker) in the updated extroot wiki:
http://wiki.openwrt.org/doc/howto/extro … aker.trunk

It also includes instructions on how the new block-mount works.

it works!thx!

This don't work on TP-Link 1043ND.
