Is OpenCloud able to use a SMB share as a data directory?

[matthewpipes]

I'm trying to run opencloud as a docker container in an unprivileged proxmox LXC. I'm passing the SMB share to the LXC using bind mounts. I used this guide to do so. However when starting the container for the first time I'm greeted with these errors. I tried adding the user_xattr to my fstab on proxmox but not luck

I wasn't able find any information on this, hoping someone has already worked through this
