1. WinPM 格式化U盘为ext3(先删除原分区再进行新分区)
2. 插入U盘, 查看相关的设备符
root@OpenWrt:~# ls /dev/sda*
/dev/sda /dev/sda1
执行如下命令
#挂载U盘第一个分区到/mnt
mount /dev/sda1 /mnt
mkdir /tmp/root
#挂载并同步系统根目录“/”到/tmp/root, 此时可以查看本目录
mount -o bind / /tmp/root
#拷贝/tmp/root下所有文件到“/mnt”，这个其实就是你的U盘了
cp /tmp/root/* /mnt -a
umount /mnt
umount /tmp/root
#和USB启动区分
echo Booted from internal rom >> /etc/banner
echo option force_space >> /etc/opkg.conf
#修改配置文件: /etc/config/fstab
config mount
option target /mnt
option device /dev/sda1
option fstype ext3
option options rw,sync
option enabled 1
option is_rootfs 1
option enabled_fsck 1
重启路由器, 正确信息如下
root@OpenWrt:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 1.8G 20.7M 1.7G 1% /
/dev/root 2.5M 2.5M 0 100% /rom
tmpfs 14.4M 80.0K 14.3M 1% /tmp
tmpfs 512.0K 0 512.0K 0% /dev
/dev/sda1 1.8G 20.7M 1.7G 1% /overlay
overlayfs:/overlay 1.8G 20.7M 1.7G 1% /
#错误如下
root@OpenWrt:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 4.7M 296.0K 4.4M 6% /
/dev/root 2.5M 2.5M 0 100% /rom
tmpfs 14.4M 80.0K 14.3M 1% /tmp
tmpfs 512.0K 0 512.0K 0% /dev
/dev/mtdblock3 4.7M 296.0K 4.4M 6% /overlay
/dev/sda1 1.8G 33.5M 1.7G 2% /tmp/overlay-disabled
overlayfs:/overlay 4.7M 296.0K 4.4M 6% /
解决: 此时可以挂载在 /tmp/overlay-disabled.
重新用WinPM 格式化U盘, 重新启动后正常.
root@OpenWrt:~# df -h

/dev/sda1 1.8G 13.6M 1.7G 1% /mnt
overlayfs:/overlay 1.8G 13.6M 1.7G 1% /tmp/root
解决:
umount /mnt
umount /tmp/root
