Well, that does seem like a bug at first glance.

Admin philosophy aside - when I set up my pool like this it stil creates a single three-way mirror for swap:
pool: fusion
state: ONLINE
scan: none requested
config:

Ok ... no matter what will be coming out of this. I don't like systems changin $stuff under the hood without me knowing, I am root, I control how things are set up. I want computers to do as I say, not try to guess what I intend.
I can live with a TrueNAS doing weird things no human sysadmin I know would. It's still the best system around.
Best regards,
Patrick

If you are hugely dependent on swap space, I'm sorry but you have much bigger problems to worry about.

Hi folks,
Version: TrueNAS-12.0-MASTER-202004071325
instead of two mirror pairs TrueNAS configures one three-way mirror:
