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 bill

Manjaro 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

This said, there is an easy way out: Give btrfs more space ;-)

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

From now on this usb-partition belongs to your volume! Do not boot without it. Do not reboot at all in this stage! This stick has to stay until btrfs device remove has completed.
look for old snapshots you don´t need, remove them now
or delete some files you do not need
Do this until your disk will be not more then 95% full
