Configuration advice requested about updating from Core to Scale

TrueNAS General

In another thread I asked about hardware compatibility - now I’m seeking some advice about software and configuration. Currently running TrueNAS-13.0-U6.1 on a Supermicro X9SCM-F system.

  1. I’m planning to do a fresh install rather than update from the Core system because I want to change the system boot mode from Legacy to UEFI (if you don’t know what this means, then no worries… it just means you’re not old enough to have experienced the “good old days.” I’m inclined to install 25.04.2.6 rather than 25.10.0 as I don’t fully trust “.0” releases.

  2. The apps in my FreeBSD jails will have to be reinstalled. The only critical application I’m concerned with is Plex. As far as I understand, there can be two approaches: a) using the TrueNAS app environment, or b) creating a Docker container and installing the docker version of Plex. I suspect that installing via Docker will be a bit more work - but this would have the benefit of teaching me something about Docker (plus there appear to be a number of interesting Docker apps out there.) Is the official app store reliable and reasonably up to date? Is it much work to maintain Docker containers?

    1. I currently have my OS on one SSD, my jails on another SSD, and data on spinning disks. I come from an environment where it was considered wise to keep OS and data on separate data volumes. Is this still an issue? Does it make sense to keep the OS, applications, and application containers on separate SSD’s or should I just put them on one SSD? Data will stay on the spinning disks.

I appreciate any comments or advice you care to offer. I like to make informed choices.

Thanks,

Not only does it make sense, it’s required–the boot device is only the boot device. The apps don’t have to be on SSDs (though it’s commonly recommended), but they can’t live on the boot pool.

Got it. This hasn’t changed between Core and Scale.

Thanks.

In regards to your question number 2, I migrated from having Plex in a Jail under Core to having it deployed as an App in Scale. I did a fresh install from the TrueNAS app repository and have not looked back. It was a little effort to get things set backup going from a Jail to an App but once there it’s been solid. There were some issues with the foray of TrueCharts for a brief period but those are well behind us now. I would recommend sticking with 25.04 over 25.10 especially if you have a legacy graphics card you want to use for transcoding in Plex. The 25.10 version is using a brand new set of Nvidia drivers (open source) which some users have had some instability with. As long as you don’t have a bleeding edge card you should be fine with the older drivers in 25.04.

For what it’s worth I’ve moved all my apps (Sonarr, Radarr, etc) to TrueNAS apps and find them very stable. I’ve only had one issue with Nextcloud but that was not an issue on the TrueNAS team but on Nextcloud.

My $.02 so proceed as you see fit.
