What

You can use this to mount or unmount a USB dive on Firewalla.

Why

You might want to throw a USB to backup some files or for a little extra space that doesn't impinge in Firewalla. (e.g. running a docker container)

Install

1. SSH into your Firewalla (learn how if you don't know how already.)
2. Create the file and permissions.

sudo touch /data/mount_usb.sh && sudo chmod 777 /data/mount_usb.sh

4. Save this file and change permissions

sudo curl -s -L -C -

Mount

/data/mount_usb.sh

Unmount

/data/mount_usb.sh u

Format

You may want to format the drive (NOTE: This will erase any contents!)
$ sudo mkfs.ext4 /dev/sda1

Note the "/dev/sda1" part you have to check using

$ lsblk -o NAME,TRAN | grep 'sd' | grep -E '[0-9]' | sed -e 's/─//g' -e 's/└//g'
