Hi,
Sorry if I sound like a complete idiot but after spending the last 3 hours
trying to figure out why my mounts are not working I have given up. LXC
mounts them ( i see this in the logs) en lxc_conf unmounts them (possibly
due to pivot_root).
Some background:
Host running LXC: Debian squeeze
Version of LXC: 0.7.2-1
I have create an LXC container using the /usr/lib/lxc/templates/lxc-debian
template and this went fine.
Now on my host i have a USB disk mounted to /mnt/1TB-Movies and I would like
to use it in the LXC container I just created. So I add the following to the
lxc config file:
lxc.mount.entry=/mnt/1TB-Movies
/var/lib/lxc/lxc-file//rootfs/mnt2/1TB-Movies none rw,bind 0 0
When I now start the LXC container and I set the debugging to DEBUG I notice
the following:
lxc-start 1290693817.212 INFO lxc_conf - cgroup has been setup
lxc-start 1290693817.212 DEBUG lxc_conf - mounted proc on

lxc-start 1290693817.213 INFO lxc_conf - pivoted to '/usr/lib/lxc'
This basically tells me that pivot_root is umounting the mount I just made.
Can anyone help me with this??? I have also tried putting the mount inside
the fstab for the container but same problem.
