If you are only rocking a few TBs, I'd recommend considering a way to switch to an all NVMe 2TB setup.
I don't there it yet but I'm either going to do a 4x SSD or a 8x NVMe icydock.... But some newer mobos have two NVMe slots which can get you 8 TBs that you can then slap zfs on via proxmox.
I store my documents in a 3 disk raid 5, which is backed up to a brand new NAS red, which is backed up to a 8TB external via Borg, and finally to my 1 TB OneDrive via rclone.
So at this point, no...
Not a great forum for this answer or you should specify how much traffic you are pushing on your self hosted, home network and whether or not you expect to use the routers tunneling.
That said, I'm a fan of the glinet stuff having used the mango and opal. But for any serious hosting you'll need more than the ports provided on those travel routers.
I feel that winscp is lying to you. How'd you mount that path in the docker lxc? Proxmox GUI?
By the way I'm just encouraging you to keep on going. Permissions from the host to an lxc to a docker is a huge pain in the butt but really is the right way to do it and folks should not run privileged containers.
If you are running your docker in an unprivileged lxc (which you should be) proxmox is going to change the UID/gid to a low number.
I'm assuming that in the docker lxc you correctly mounted /mnt/plex and you can touch/remove files on there? If not, your folder mount is wrong to the lxc.
If you can, and are using docker compose, there is probably an environment value to set the UID/GID of the user for jdownloader. Set this to root or some other user that has the right access on your lxc.
Damn, just downvote and move on.
I have two GPUs in a single tower.
A GTX 750 to that I share with my LXCs. It does jellyfin transcode, frigate nvr for 3 cameras, kasm accelerated desktops, xfce4 pve host acceleration, Jupyter tensorflow, ersatz tv transcode, and I plan to use it for immich. At most it is taxed about 25 percent but I plan to have a lot more nvr and jellyfin streams.
I also have a 1660 ti passed to windows 11 VM for my gaming VM. I use sunshine and moonlight for remote gaming but I also roll easy diffusion for some image generation. I had an LLM but (https://github.com/oobabooga/text-generation-webui) but it was too slow for what I'm used to - I just use bing chat and now meta on whatsapp for my personal and an LLM I have access to at work.
