Hi,

1) I have formatted the second partition(/dev/sda2) of my USB stick to ext2.

2) It is recognized by the web interface of TP-LINK but it is not mounted...

3)OpenWRT version is 12.09 "Attitude Adjustment and I follow these steps http://wiki.openwrt.org/doc/howto/extroot#openwrt.12.09.attitude.adjustment

4)My problem occurs when I try to mount the filesystem for the new external rootfs to a manually created directory /mnt/share

I have tried :      mount -t ext2 /dev/sda2  /mnt/share

                         mount /dev/sda2  /mnt/share

And I always get ---> mount: mounting /dev/sda2 on /mnt/share failed: Invalid argument

It seems that mounting cannot be done.

I dunno if I have to change sth in etc/config/fstab . I only changed "option fstype 'ext2'" . I attach it for completeness...

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 '/overlay'

        option options 'rw,sync'

        option device '/dev/sda2'

        option fstype 'ext2'

        option enabled_fsck '0'

        option enabled '1'

config swap

        option enabled '1'

        option device '/dev/sda1'

Best,

Theodoros

What version of openwrt do you have?

I am guessing 12.09 "Attitude Adjustment" based on openwrt hardware page for TP-LINK MR3040

if so you were reading the wrong instruction set
see <http://wiki.openwrt.org/doc/howto/extroot#openwrt.12.09.attitude.adjustment>
