You need to create mount script in openvz configuration directory (/etc/vz/conf) with name <veid>.mount. If you need to mount filesystem to all containers than name of script should be vps.mount and inside script ${VEID} variable can be used.
 
 
 
Example:
 
<pre>#!/bin/bash
 
mount --bind /mnt/disk /vz/root/${VEID}/mnt/disk
 
exit ${?}</pre>
 
 
 
For unmounting filesystem file vps.umount can be used.
 
 
 
Example:
 
<pre>#!/bin/bash
 
umount /vz/root/${VEID}/mnt/disk
 
exit 0</pre>
 
 
 
''Notice:''
 
<veid>.umount scripts are not very necessary: everything will be umounted automatically on VE stop. But you should than mount with -n option in mount script.

To mount a file system inside a container, you have several choices:

  • NFS, when container as an NFS client
  • FUSE (filesystem in userspace)
  • Bind mounts from Hardware Node

Also, you can grant a container an access a physical block device, and use that device from inside the container. Not all file systems are working inside a container; check /proc/filesystems inside a container to find out.
