Problem

I have a VPS with id 200 and a script 200.mount to do a bind mount for a file system to a mountpoint in the VPS filespace and another script 200.umount to unmount the filesystem. This is a techniques I have used for some time on an older version of OpenVZ

On starting the VPS it seems that the 200.umount script is being run and the 200.mount script does not get executed. If I rename the 200.umount script and start the VPS then the mount script is called correctly, however on shutdown the filesystem is not unmounted.

running the scripts manually with the VPS active mounts and umounts the filesystem as expected.

Am I doing something wrong? I am basing this on a 3 year old pdf document: "OpenVZ User's Guide" version 2.7.0-8, copyright 2005. Have there been changes to the api? if so is there a more up-to-date version of the User's Guide available?

file 200.mount:

#!/bin/bash
/bin/mount --bind /var/www/docs/ECE /vz/root/200/var/www/ECE/
exit ${?}

file 200.umount:

#!/bin/bash
/bin/umount  /vz/root/200/var/www/ECE/
exit ${?}
