Freeing eMMC space on the Beaglebone

After installing the LXQt Debian image from eLinux.org, then Pi-Hole, then Docker in order to run Home Assistant, I quickly ran out of space on the onboard 4GB eMMC.

Freeing eMMC Space

  1. Backed up the eMMC using this script <link>. Saved the SD card image in OSX using Disk Utility. Then compressed it into a zip file.
  2. Installed the Debian Stretch Console Snapshot image from eLinux.org <link>.
  3. Made a static IP by reserving a static DHCP assignment in my router configuration. I tried to assign a static IP for eth0 on the BBB <link> but it didn’t take, dunno why. Maybe I should do this? <link>
  4. Checking the drive free space using “df” <link>, I now have 2.9GB of space free, an enormous improvement from before.
  5. Debian kept complaining about locales, so i updated them <link>.
  6. Fought with /etc/init.d to get the LED disable script to run on startup; the symlink worked when named “S99rc_local.sh” using a script named “rc_local.sh”. Seems the naming convention must start greater than “S01” and the name after this must match the script name exactly.

Installing Pi Hole

  1. Had to install curl <sudo apt-get install curl>.
  2. Ran the online installer <link>.
  3. Updated Gravity, the Pi-Hole blocklist (it installs empty).
  4. Did all the things in my Pi-Hole on BBB post <link>.

Installing Docker ** Did not finish, installed Home Assistant on a spare RPi 3B+ and called it a day. **

  1. Installed Docker CE (Community Edition) <link> NOTE: for BBB you must use the repo under the “armhf” tab. Configured Docker to run on boot <link>.
  2. Cleared/formatted my 8GB SD card with FAT32 <link>. Added boot-time auto mount <link> <link2>. Changed the default path for Docker images to be on the SD card at /docker_configs by way of a new JSON daemon config file <link> <link2>.
  3. Fun fact, aufs requires an ext4 filesystem so I reformatted as ext4.
  4. TBD?
