A network attached storage (NAS) provides file-based data storage
to other devices on the network. The files can be shared between the devices.

This article is complementary to OpenWrt.

Mount Points

To use an external storage device, the device needs to be mounted.

Packages

• kmod-usb-storage
  Kernel module for USB storage support.
• block-mount
  If this package is installed, the web interface shows Mount Points under System.
• kmod-fs-ext4
  Kernel module for EXT4 (native Linux file system) support.
• ntfs-3g
  In case NTFS (native Windows file system) support is needed,
  this user-space driver provides read and write access.
  In general, the performance of user-space drivers is not as good as
  drivers implemented as kernel modules.

Configuration

In the web interface, the option Mount Points edits the following file:

/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 enabled '1'
    option label 'SSD'
    option target '/mnt/ssd'

Network Shares

Packages

• samba4-server
  The actual server software that shares the files.
• luci-app-samba4
  This package shows Network Shares under Services in the web interface.

Configuration

The option Network Shares edits the following file:

/etc/config/samba4

config samba
    option workgroup 'WORKGROUP'
    option charset 'UTF-8'
    option description 'Samba on OpenWRT'
    option interface 'lan'
    option macos '1'
    option allow_legacy_protocols '1'

config sambashare
    option name 'ssd'
    option path '/mnt/ssd'
    option read_only 'no'
    option guest_ok 'yes'
    option create_mask '0666'
    option dir_mask '0777'

Do not forget to restrict the access to the share to the LAN interface.
