Hello community,
I am new to TrueNAS(and linux in general), AI advised to use TrueNAS for my purpose, but as soon as I installed everything I ran into a wall trying to configure hot/cold data split…
I planned to have a very simple setup - single AD, no replication, only two disk pools - a 2x SSD mirror (2x2TB) and 2x HDD mirror(2x16TB). The idea was to have them both looking as a one single share to my AD clients, but to store rarely used files on HDD and all R/W intensive to keep on SSD. AI now prompts me to create two pools and a “UnifiedShare” in both pools, with a cron script to move files based on the access timestamp from “Hot_pool” to “Cold_pool”. But is it possible to merge two pools into a single share? I have read a bit about the dupe feature of TrueNAS and I have a feeling that this feature could be better fitting that purpose. Or maybe there is a dedicated feature for cold/hot split? If there is any proven guide on how is it better to achieve that, I would really appreciate a link. And if not - please also let me know.
Thank you in advance,
Igor.
Here is the problem.
TrueNAS is not suitable for the requirement you described.

TrueNAS doesn’t have any feature like you’re describing. You could, with appropriate scripting, move data around in any way you like. But there isn’t any way to make two pools appear as one share.
Thank you guys, another AI trap 
If there are any feasible free ways to achive that, I’d appreciate the suggestions, otherwise the question is closed.
