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.
 
−
 
 
−
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
 
−
<pre>
 
−
mp0: /target/test,mp=/target
 
−
mp1: /mnt/pve/freenas,mp=/mnt/pve/freenas
 
−
</pre>
 
−
reboot your container and log in:
 
−
<pre>
 
−
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
 
−
</pre>

== Manual method ==
 
−
* This works as of 2015-09-13 using lxc-pve: 1.1.3-1 . 
 
−
:add this to the .conf file in /etc/pve/lxc
 
−
lxc.mount.entry: /host/folder container/folder  none bind,create=dir,optional 0 0
 
−
'''Note:''' Do not put a '/' before the container target
 
−
 
 
−
'''Note:''' This adds an entry to "/var/lib/lxc/<containerID>/config" in the correct format.  Do not edit "/var/lib/lxc/<containerID>/config" manually as that is overwritten on container boot.

−
== Bind mounts and backup ==
 
−
Note that bind mounts are not going to be included when you backup the container by default. You need to
 
−
set the backup flag to include them.
 
−
 
 
−
mp0: /target/test,mp=/target,backup=yes
