Avoid to get out of space with btrfs!
Don't be stingy on storage space when creating a btrfs volume. A btrfs volume should normally only be 80% full. Then it is advisable to adjust the volume. In an emergency, 90% are okay too. But that is neither advantageous for the Btrfs volume nor for an SSD.
Don't forget to include the snapshots in the billManjaro is a rolling release distribution. There will be a lot of changes over time.
Tip: Check how close you are to "out of space". Look at Device unallocated: (not at Free (estimated):) 1
root # btrfs filesystem usage / COPY TO CLIPBOARD
Get out of jail

add a (unformatted) partition (for example a fast extern USB-Stick with 8GB) to the btrfs-volume with
root # btrfs device add /dev/[sdz4] / COPY TO CLIPBOARD
