EXTROOT script doesn't work

[varma]

hi everybody,
I'm trying to use the "automagical" extroot implementation in the USB Storage page, but it doesn't work at all.

My WR1043ND has this Gargoyle build: 1.7.X (Built 20150207-0832 git@3344fb7).

After some tests I format my 1 GB pendrive with gparted into:
512 MB ext4 (I would like to use it as extroot)
256 MB ext4 (I'm using it as plugins_root)
190-200 MB swap

and the plugins page accepted the pendrive giving me the ability to install the addons.

This could be a good start to set the extroot manually, but it's really complicated to myself.
Is there anybody able to explain it in a easy way??
Might be possible to execute a script to set it up?
Might anybody share the important configuration files to make it easy?

I found this into the wiki page of OpenWRT:
http://wiki.openwrt.org/doc/howto/extroot

Some users reported a problem with Barier Breaker 14.07 (and RC versions) on ar71xx devices, the problem was solved by user S-trace, thanks to him. The partition won't mount as /overlay, but still mount as /mnt/sdax. To get the right uuid run block detect.

Might be due to this problem?
Thank you very much as always!

Hello again,

I freshly installed the new 1.7.2 version
an tried to setup extroot in the "USB Storage" page with the following box:

Code: Select all

Use Disk As External Root (Extroot)
When using an external root drive or extroot an external USB drive becomes the root drive on your router. This can enable a very large root drive, but if you remove the drive all configuration changes since the extroot was activated will be lost. 

the router rebooted and this is the "mount" situation:

Code: Select all

/dev/root on /rom type squashfs (ro,relatime)
proc on /proc type proc (rw,noatime)
sysfs on /sys type sysfs (rw,noatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)
/dev/mtdblock3 on /overlay type jffs2 (rw,noatime)
overlayfs:/overlay on / type overlayfs (rw,noatime,lowerdir=/,upperdir=/overlay)
tmpfs on /dev type tmpfs (rw,relatime,size=512k,mode=755)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
debugfs on /sys/kernel/debug type debugfs (rw,noatime)

and this is my "dmesg":
