Hi, I follow all steps on wiki and after I check https://forum.openwrt.org/viewtopic.php?pid=142907
But in my case the problem is that it does not start in any way, though I can manually mount everything without problems.

Maybe I've run into a bug, because the most strange is that when I connect the USB drive lost automatic DNS settings on the modem 3G (and I must manually configure clients to point to ISP DNS). I had thought that could be related to energy consumption, but before checking that all was a failed DNS ... (wget say me 'bad address 'downloads.openwrt.org' but I can ping to DNS server...).

The truth is that I can not think what to do. As I've tried the suggestions of the message https://forum.openwrt.org/viewtopic.php?pid=142907 but can not get about to start.

Goal is: sda1 = overlay, sda2 = home, and sda3 = swap (I use UUID better), and now for testing I have:

Edited:

config 'global' 'automount'
        option 'from_fstab' '1'
        option 'anon_mount' '1'

config 'global' 'autoswap'
        option 'from_fstab' '1'
        option 'anon_swap' '1'

config 'mount'
        option 'target' '/mnt/sda1'
        option 'device' 'UUID=aa3e8fc7-5921-49c1-9933-99a9d392a7ce'
        option 'fstype' 'ext3'
        option 'options' 'rw,sync'
        option 'enabled' '1'
        option 'enabled_fsck' '0'

config 'mount'
        option 'target' '/mnt/sda2'
        option 'device' 'UUID=d3e5f1e0-7877-4268-8656-a6dd6e2131db'
        option 'fstype' 'ext3'
        option 'options' 'rw,sync'
        option 'enabled' '1'
        option 'enabled_fsck' '0'

config 'swap'
        option 'device' 'UUID=7310a383-4ace-4564-92a3-a3b286746777'
        option 'enabled' '0'

With option 'anon_mount' '1' & option 'anon_swap' '1' I get it work on hotplug.

Automatic mount over /mnt/sda1 is working, but over /overlay configuration is missed...

Regards.

Hi, I was lucky and was able to configure it, but instead of /overlay I use a rootfs.
A package that I have included in the compilation is autofs4 (perhaps the missing to function properly).

Sysupgrade and fist /etc/config/fstab

config global automount
        option from_fstab 1
        option anon_mount 1

config global autoswap
        option from_fstab 1
        option anon_swap 0

config mount
        option target   /
        option device   /dev/sda1
        option fstype   ext3
        option options  rw,sync
        option enabled  1
        option enabled_fsck 0

config swap
        option device   /dev/sda3
        option enabled  0

After boot I have a /tmp/whole_root-disabled

mkdir -p /tmp/cproot
mount --bind / /tmp/cproot
tar -C /tmp/cproot -cvf - . | tar -C /tmp/whole_root-disabled -xf -
umount /tmp/cproot
/etc/init.d/fstab whole_root_enable

After boot I have a rootfs working. Now a fix swap and ready .

Now that I have more space I try to find problem with dns server....

Regards.

Hi, after use of USB disk I have a /tmp/resolv.conf.ppp but it's ignored... :-? I'd copy /tmp/resolv.conf.ppp to /tmp/resolv.conf and I have dns working again (Edited: on LuCI I see a resolve file /tmp/resolv.conf.auto, that I change to /tmp/resolv.conf.ppp). Regards.

I have the same Router and use it with an overlayd Root on an 4GB USB-Stick that is connect togeher with an USB-Sound Device through an simple hub.
I took the folowing steps (after installing the firmware and setting up the lan so that opkg can work, of course)
1. starting (!) fstab like explained at http://wiki.openwrt.org/doc/uci/fstab
2. Setting up the rest as explained at https://wiki.aseith.com/pages/viewpage. … Id=4161740 (this is in german, but the code is universal, I would say ;-) )

That worked for me, I use openwrt-ar71xx-generic-tl-mr3220-v1-squashfs-factory.bin as firmware-version from http://downloads.openwrt.org/snapshots/trunk/ar71xx/ which I downloaded at the 22.01.

Hi, thanks Mudhenn, but in german I don't understand any . However the trick was to do in the first login after sysupgrade, because that is what has allowed me to generate the rootfs properly.
