Migrating to OMV from trueNAS scale questions

I was wondering if any one has migrated from trueNAS into OMV. For my application trueNAS is no longer working out. As I need new features on a more updated pace than the glacier progress of trueNAS. I know I have to install OMV extras and the promox kernel to get ZFS support. I have no backups and no other storage locations to handle the current amount of data that I have(Mostly Videos). So migrating to a more linux centric filesystem is out of the question. I was also looking at trying to install at least linux 6.2+.

I have a dual GPU in my NAS and one is an A380 which requires the 6.2 kernel to work and the other is a NVIDIA 730. I was wondering if there are any pitfalls I should be aware of. I haven't seen any red flags I should be aware of through google. Compatibility with GPU pass-through and docker is what I am trying to achieve as my Jellyfin container desperately needs a GPU encoder for 4k h265 files.A Ryzen 7 5700x with all CPU resources available to the container can barely pump out .75x transcode speeds. And I am also looking at HDR to SDR tansncoding which in Jellyfin requires a GPU.

I ran Arch as a daily driver for over a year and if I have to I would turn that install that in a server but I would prefer an OS that out of the box with some tweaks work with as NAS with a remote web GUI interface.

Thanks for any thoughts or guidance.

I went with a cheap/bare bones option when first building the server which was the 730. As the Ryzen 7 doesn't support integrated.(I have ECC memory). I was looking for a GPU specifically for hardware encoding when my server couldn't transcode 4k videos in h265(It can in h264 but for what ever reason only on the web transcode. Something breaks down when trying on their Roku app) and I read the A380 is great for it even supports AV1 and up to 8k the problem is Scale is very locked down and now way to add in parts of the kernel and or update it to make it compatible

I thought I would close this thread out with a warning to trueNAS users looking to do this. DON'T. Unless you know the ins and outs of ZFS and its feature flags. There isn't 1:1 translation between what ZFS on OMV is compatible with and what trueNAS uses. And I have not seen any one publish a guide to do this. The only way to migrate from trueNAS to OMV is a rsync task once you have two systems. I spent over two hours with what should be out of the box stable and couldn't get it working. Heres to trying to figure out to get Hardware encoding on trueNAS...

Not sure. It shouldn't be an issue with scale as scale is based on Debian so any feature flags they set should be compatible with OMV but I kept getting an error when trying to import the pools via the webGUI both all pools and named specfically. I didn't bother with the CLI frustrated at that point

Yeah, I am in the process of reinstalling OMV. My reinstall of trueNAS failed. Guess its just my luck of the night. I remember I was getting a 500 error when trying to import the pool. I will let you know if it happens again. If I get it working I will definitely post my steps.

As I thought feature flag. This feature flag is new to ZFS 2.2 Is there any way to update to ZFS 2.2 if its in trueNAS it defiantly is stable. Is there an experimental branch of this plugin that is using 2.2?

 500 - Internal Server Error

yeah i spent 30 mins google to see if I could find a way to do it and I didn't see anything. I guess I am just going to have to buy a 2.5 Gbps switch and just run my heavy duty applications media server on my windows desktop for 2 years as that is about how quickly things get adopted at trueNAS ... I am just surprised an anything is lagging behind trueNAS.

Tried OMV 7 on my first attempt as it appears it should be stable soon seeing how the latest stable branch is prep for OMV 7. I let it do an update before attempting plugins and OMV failed to update the kernel/generate a new intrafms. I tried forcing it to update but couldn't get past the bad install of the kernel update. I don't recall the exact error message.

At this point I am just going to go with Arch if it going to be this much a struggle to get something else beside trueNAS working. Arch stays up to date and is on a rolling basis. Once you get it running it generally doesn't break. It just sucks to have to do all the back end work to get it there. Even as my daily driver took a full day to get stable.

Yes. I found it odd it was trying to install rasberry pi firmware. I chalked the failed update to the fact I was installing OMV onto a SSD USB drive and it thinking that was the environment it was looking for. That's I why didn't really try getting OMV 7 working as it is still in testing.

I can try again. Cause I really do not like doing Arch installs. And ZFS complicates things on Arch by having a strict kernel requirement
