Haha, well, I may have missed it or I may have seen it and scrolled past it because I had no reason to be interested in this kind of low level stuff. Database? It’s like the road when driving a car: you don’t really think about it until it gets bad.
It even took me a while to find what you (probably) where referring to now:
But on the way, I found this useful specification of what “not often” means:
To summary my lesson from this topic:
The confusion around the original issue was due to a combination of rather rare circumstances which meant that all standard instructions failed for various reasons:
- two-container setup
- need for (rare) database upgrade (which requires more disc space than other upgrades)
- only 20 GB SSD
Points 1 and 3 are still true but probably not nr. 2. Yet, I still had problems doing the web_only upgrade. So the db upgrade probably worsened things but it seems it was a mistake to run the two-container setup on 20GB.
