GPT PMBR size mismatch (246303 != 250069679) will be corrected by write.
The backup GPT table is not on the end of the device.

2 安装parted
opkg install parted
#修复
root@OpenWrt:~# parted -l
Warning: Not all of the space available to /dev/sda appears to be used, you can
fix the GPT to use all of the space (an extra 249823375 blocks) or continue with
the current setting?

3 安装cfdisk ,分配剩余磁盘空间
opkg update
opkg install cfdisk
#开始分区,未分配的磁盘空间
cfdisk /dev/sda 
# 选择NEW --.输入空间大小
4 分区查看格式

opkg update
opkg install block-mount
reboot#web 登录openwrt 选择 系统-->挂载点 找到新创建的分区
#ssh 登录openwrt
#逐条执行，确保成功
mkdir -p /tmp/introot
mkdir -p /tmp/extroot
