Build Home Router with OpenWrt – USB Storage Auto Mount

Block mount

Add CONFIG_PACKAGE_block-mount=y to target/linux/brcm2708/configs/rpi3b_defconfig to get block mount support

USB storage auto mount

I wanna share movies on the usb disk to phone, tablet, TV and laptop, so I expect OpenWrt will auto mounting my usb disk when inserted, this can be done through fstab like this:

diff --git a/target/linux/brcm2708/base-files/etc/config/fstab b/target/linux/brcm2708/base-files/etc/config/fstab

+       option options  rw,sync
+       option enabled  1

By applying this patch the router will detect if /dev/sda1 exists, if true it will be mounted to /mnt/sda1 automatically, so minidlna server will see this disk and scan the media in it.

Next post will show how to add minidlna support for OpenWrt.
