Now I created four mirrors using the zpool add -f poolname mirror /dev/sdXX /dec/sdXX command to a already existing pool and removed the last disk in there before creating the last mirror. So the forbidden mirror looks like this:
It’s an interesting learning experience, to play around in a “test lab”.
But please don’t do this when you build your TrueNAS box to hold your data. The GUI and middleware might have a heart attack when a “member device” begins to fail.
There is nothing wrong with playing like this, but if you want to do this in production use then you might be better off looking for a NAS O/S that supports this type of mixed drive usage (like UnRaid???)
I definitely won’t do this once I start buying disks, as I want it to be worry free after I get the thinkering out of my system. In practice however I don’t really see how this would go wrong in daily operation as TrueNAS still has metal access to the disks and there is one drive of fault tolerance.
The negatives would be lower performance as the r/w head on the partitioned disks would need to jump between partitions. It could be a mess untangling a large pool made in this manner when replacing disks, and for sure resilvering would be interesting to say the least. I assume one would have to manually recreate the partitions lost on a replacement disk?
…there is positive and negative, energy goes from greater potential to lower potential until equalized because that of lesser potential sinked/pulled it from the greater potential. The names: positive and negative is just names. Like in a plug, the male and female.

As a man, is expected to post without a doubt, guiding. But you’re inviting people to think that maybe, just maybe… .
Nope. The answer is no. A redundant unquestionable no.
In this forum. Now, with a drink in hand, chatting along, we can talk about it. But in a post regarding TrueNAS as a possibility, without any bad vibe, the answer is still no.
