Does anyone know if there is a way to increase the length of time a friendica node retains posts? I'd really like to be able to go back farther than four pages worth of posts which seems to be about the limit.

I'm not anywhere near maxed out on disk:
Filesystem Size Used Avail Use% Mounted on
204.122.16.128:/social 2.6T 61G 2.4T 3% /social

And I'm more than willing to purchase bigger drive(s) if/when that becomes
necessary.
