So i had an old 13.3 install and i am creating a new storage server running 25.10.0 - Goldeye. setup is straight forward:
i7 9th gen
32GB ram
512 GB Nvme OS
2 x 24TB Seagate Exos for the storage pool
My question is can you partition the Nvme install TrueNas on say a 50 GB partition and then create a second partition that i can run apps off of like plex?
No, just like you can’t do it in CORE. TrueNAS, and FreeNAS before it, have always and only supported having a dedicated boot device. Yes, you can hack around it if you like, but you’ll be deep into unsupported territory if you choose to do this.
