Hello

If I do
mount -n -t simfs /somepath /vz/root/101/mnt/test -o /mnt/test
Then
vzctl exec 101 df

It tells me that the moint /mnt/test has 10GB of data.
How can I set the quotas on this mount point?

Specifically what I am trying to do is allow a container to access the
private area of another container eg
mount -n -t simfs /vz/private/200 /vz/root/101/mnt/test -o /mnt/200

CT200 would not be running in this example. I would like to be able
to set the moint point at /mnt/200 to have the same disk quota limits
as are set for CT200. This allows CT101 to act as a rescue shell for
CT200. Currently my rescue shell works just fine, but only because
none of our users yet have more than 10GB of data.

An alternative approach would be if there was a way of mounting
/vz/root/200 without actually starting CT200, and then use a bind mount:
mount --bind /vz/root/200 /vz/root/101/mnt/200

I don't think mounting a container without starting it is currently
supported, but this would be a relatively straightforward change to
vzctl? I could submit a patch if I get it working and you think it
would be a worthwhile feature.

In fact it's totally supported
vzctl mount 200

I'm not sure where I got that idea from.
