This is an experimental feature.
 
 
 
Bind mounts allow you to access a directory, or a storage volume from your Proxmox VE host inside a container. There can be many purposes:
 
* Accessing your home directory in the guest
 
* Accessing a USB device directory in the guest
 
* Accessing a NFS mount from in the host in the guest
 
 
 
Note that the device you want to use has to be already accessible in the pve host. For security reasons, it is not possible to mount a device of NFS share directly in the guest.
 
 
 
== Step by step examples ==
 
Suppose you want to access the following directories in your LXC container with ID100:
 
* /target which is a local directory
 
* /mnt/pve/freenas which is a NFS mounted directory
 
 
 
Then you need to add the following parameters to /etc/pve/lxc/100.conf
 
 
 
mp0: /target/test,mp=/target
 
mp1: /mnt/pve/freenas,mp=/mnt/pve/freenas
 
 
 
reboot your container and log in:
 
 
 
pct enter
 
mount | egrep '(target|freenas)'
 
/dev/dm-0 on /target type ext4 (rw,relatime,errors=remount-ro,data=ordered)
 
freenas.local:/mnt/TranstecThrough/exported
 
 
 
== Another method ==
 
*this works 2015-09-13 using lxc-pve: 1.1.3-1 . 
 
:add this to the .conf file in /etc/pve/lxc
 
lxc.mount.entry=/bkup  bkup  none bind 0 0
 
'''Note:''' Do not put a '/' before the target
 
 
 
== Caveats ==
 
Note that bind mounts are not going to be included when you backup the container.
 
This is a design decision: since bind mounts might be shared between many containers, it makes sense to backup their content on the host, not from inside the container.
