umount /tmp/cproot

Make the router boot from flash drive

Login to router via WinSCP (/index.php/blog/item/24-winscp-windows-secure-copy) and edit the /etc/config/fstab file. Below is my original configuration.

a

ssh with putty

cp /etx/config/fstab /etx/config/__fstab

vim /etc/config/fstab

config 'global'

option anon_swap '0'

option anon_mount '0'

option auto_swap '1'

option auto_mount '1'

option delay_root '5'

option check_fs '0'

config 'mount'

option target '/mnt/sda2'

option uuid 'cdfd73b1-8c85-d001-c0f0-72b18c85d001'

option enabled '0'

config 'swap'

option device '/dev/sda1'

option enabled '0'

Chage it to the following. Take note that target is changed from /mnt/sda1 to /

config 'global'

option anon_swap '1'

option anon_mount '1'

option auto_swap '1'

option auto_mount '1'

option delay_root '5'

option check_fs '0'

config 'mount'

option target '/'

option uuid 'cdfd73b1-8c85-d001-c0f0-72b18c85d001'

option enabled '1'

config 'swap'

option device '/dev/sda1'

option enabled '1'

/etc/init.d/fstab enable

reboot

check that everything went goot by typing:

df –h

root@OpenWrt:~# df -h
