Pretty sure truenas scale can host everything you want so you might only want one server. Use Epyc for the pcie lanes, and a fractal design r7 XL and you could even escape needing a rack mount if you wanted. Use a pcie to m.2 adapter and you could easily host apps on them on a mirrored pool and use a special vdev to speed up the HDD storage pool

The role of the proxmox server would essentially be filled by apps and/or VM you could turn on or off as needed.

Have you got a recent copy of the configuration file?

I’m not the best person to explain the how or why but they are looking at Q3 for beta and Q4 for main release.

I’m running Immich, Nextcloud and Jellyfin on TNS and it’s fine. Nextcloud takes a bit of work though.

TrueNAS Scale will have Docker in the next release in August, along with the ability to expand Vdevs.

Probably not that helpful but Truenas Scale and the Nextcloud App, and then just used the Collabora “plugin” as I gave up using a separate Collabora App because I couldn’t make them work together. Probably going to have to fix everything again in August when the next TNS update drops (Electric Eel) and enables vDev extensions.
