So would a 60 liter fermenter be adequate for a 40-50 liter batch during
primary fermentation?
Would you then use smaller fermenters for the secondary fermentation and
fill the fermenter up leaving no space for oxygen?
I suppose that oxygen in the fermenter during secondary fermentation is not
desired?

I fill up to 25 liters in a 30 liter bucket. If the primary fermentation
goes wild, I get foam out of the airlock, so probably I should fill a
bit less...
I don't see any problem with "too much" airspace in the fermenter. In
the beginning the yeast will make good use of the oxygen it can get hold
of. Then it starts producing CO2, which will first settle as a layer
over the wort, and soon fill the whole fermenter and push all air out.
I don't remember how much CO2 a fermentation produces, but I think it
was measured in cubic meters...
In a secondary you won't be producing as much CO2, and you should not
oxidize the beer. Still, I don't see any problem with large fermenters
and small batches.
Don't worry,
it will be beer anyway
