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.
Mount filesystem on VE start
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 ${VEID} variable can be used.
Example:
#!/bin/bash mount --bind /mnt/disk /vz/root/${VEID}/mnt/disk exit ${?}
For unmounting filesystem file vps.umount can be used.
Example:
#!/bin/bash umount /vz/root/${VEID}/mnt/disk exit 0
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.
