[Proxmox] Mount dataset into LXC
Open LXC config file in your favorite editor. In this case the container name is 101:
nano /etc/pve/lxc/101.conf
Append a single line for each mountpoint you want to add. The first mountpoint is “mp0”, the second “mp1” and so on.
mp0: /data/music,mp=/mnt/nfs/music
First the source (my zpool “data”, folowing the dataset name “music”), after that the destination inside the container beginning “mp=”.
