Having trouble mounting SMB shares in LXC (lemm.ee)

submitted 1 year ago by [email protected] to c/proxmox

3 comments fedilink hide all child comments

For starters, I'm ultra new to proxmox and linux. I have my old PC running proxmox in the corner of my room so I can play around and learn it.

I have my main server (running Windows) sharing an attached hard drive as a samba share for other computers on my network. I can't seem to mount this share in a fresh LXC, but I can in a PlexMediaServer LXC I created using tteck helper scripts. I'll just attach what I'm doing below. Both are using the same container template (Ubuntu 22.04).

I think it's pretty obvious that I have a problem with permissions on the bare LXC that I don't with whatever that script is going to set up the LXC and install Plex for me. I'd like to be able to mount network shares as easily as this on all my other LXCs as well. Can anyone point me in the right direction?

Is the LXC privileged or not?

[–] [email protected] 2 points 1 year ago

I just checked and the Plex container options say "unprivileged container: no"

So that seems to be it. I've only been trying with proxmox for a few days so all I've read about this is "don't do it, it's less secure". I don't really understand much about it yet.

But you helped me realize why that's happening, thank you.

The code is formatted pretty poorly on my mobile app, so here are some screenshots of the console:
