Running Onion Omega 2 from the USB external storage device

Aman Chawla

Hello,

I'm trying to expand the storage space on my Onion Omega2 (attached to an Arduino Dock 2) using a USB storage device with 15 GB of space. I could successfully format the file system on the device to the required ext4 file system, as explained in: https://docs.onion.io/omega2-docs/boot-from-external-storage.html

However, the rest of the instructions didn't work. When I try to run

opkg install kmod-usb-storage-extras e2fsprogs kmod-fs-ext4

I get the following output after some steps:

Configuring libuuid.
Configuring libext2fs.
Configuring e2fsprogs.
Collected errors:

satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-usb-storage-extras:
kernel (= 4.4.74-1-97eec485b1ee24d5b1ca0357d1dd7304) *
opkg_install_cmd: Cannot install package kmod-usb-storage-extras.

opkg_install_cmd: Cannot install package kmod-fs-ext4.

I would appreciate any help in overcoming this error.

Sincerely,

@Pavel-Metrokhin I ran the instructions on the thread you mentioned. It returned the following:

Here is my method (works with both external USB drives and the sd card just change the /mnt/xxxx and /dev/xxxx), ignore opkg errors:

opkg update
opkg install kmod-usb-storage-extras e2fsprogs kmod-fs-ext4 block-mount

#setup for external drive#
mkdir /mnt/sda1
mkfs.ext4 /dev/sda1
mount /dev/sda1 /mnt/sda1
mkdir -p /tmp/cproot
mount --bind / /tmp/cproot
tar -C /tmp/cproot -cvf - . | tar -C /mnt/sda1 -xf -
umount /tmp/cproot
block detect > /etc/config/fstab
vi /etc/config/fstab    #configure like this#

config mount
    option target        /
    option device        /dev/sda1
    option fstype        ext4
    option options       rw,sync
    option enabled       1
    option enabled_fsck  0

reboot
df -h #check sda1 is mounted as /#
