Comment on Am I corrupting my data?

Proxmox supports ZFS natively with management in the WebUI. So you could get rid of TrueNAS entirely and not need to deal with HBA pass-through or anything.
You also wouldn’t need NFS or have to deal with shares, as the data is available directly to Proxmox Containers via bind mounts.

Okay, if Proxmox can handle all that, I’ll be glad to ditch TrueNAS. However, I’m afraid that I won’t know how to migrate. I’ve found this reddit thread about someone who tried to do the same thing (I think) and accidentally corrupted their pools. About skipping NFS shares, that would be a big improvement for me, but I’m very unfamiliar with bind mounts. If I understand correctly, you can specify directories that live on the Proxmox Host, and they appear inside the VM, right? How does this compare to using virtual storage? Also, how can I replicate the ZFS pools to an external machine? In any case, thank you for that info!

Migration should be as simple as importing the existing ZFS stuff into the Proxmox OS.

Just to be clear, are you saying that when you’re using bind-mounted ZFS pools, it’s okay to write from two containers (or both the proxmox host and a container) at the same time?
Also, I think I managed to accomplish that for a VM by creating a Proxmox Directory pointing to a path in a zpool, adding it to the VM using virtiofs, and mounting it within the VM. I’m not sure if writes from both the VM and the host are safe in that case either, though.

You wouldn’t want to write to the same file at the same time, but otherwise it works fine.

Okay, I have one of the pools that is pretty empty and has non-critical data, and I think I’ll try migrating that first, and see if it’s imported correctly by Proxmox.
About Containers, I think I’ll have to do some more research because I think I haven’t fully understood yet how they compare to VMs. Or like, when I should the one over the other. I guess I could have a Container with a bind mount to a dataset that I want to be shareable over NFS or SMB, and handle that from whatever OS I put in the Container, right? But, I could also have a VM do that, and though it wouldn’t be able to share the data with other VMs, it can do it over NFS, can’t it? What are the advantages of doing one thing over the other?
Well, in any case, thank you for your patience, for going over each detail and taking the time to correct me where I’m wrong. I’m learning a lot, so thank you!
