I regretted that I initially configured my swap space to just 1GB.
I am running out of memory with intensive apps such as GitLab.
And so I needed to increase swap.
It is rather simple, and very similar to the original post on adding swap memory.
# Assume I need another 2GB # Allocate 2GB in another file. Let's call it swapfile2g. sudo fallocate -l 2G /swapfile2g # Make it secure sudo chmod 600 /swapfile2g # Activate it sudo mkswap /swapfile2g sudo swapon /swapfile2g # Confirm again there's indeed more memory now free -m sudo swapon -s # Configure fstab to use swap when instance restart sudo nano /etc/fstab # Add this line to /etc/fstab, save and exit /swapfile2g none swap sw 0 0
