If we want to make available a partition from host node (HN) to a container which option, private or root, to use and how?
I have a /root1 and /root2 partitions available in HN that I want to use for containers 101 and 102. I tried using as:
vzctl create 101 --root /root1 ...
it didn't work (ie the install proceeded on the usual /vz/private/101), then I tried to use it as:
vzctl create 101 --private /root1 ...
That seemed to have created the container's file system on HN's /root1, but for some reason either during a poweroff or reboot I lost the file system from /root1.
It is not clear as to how these options can be used and how are they related to each other, specially in regard to making a HN partition available for a container's root file system use.
Thanks

I have retried --root /root1 and --private /root1 and this is what I observed.
1. If I pass --root /root1, then what is happening is that container, as usual, is getting setup under /vz/private/101 and /root1 is not used during the creation. However, if the container 101 is started, VZ seems to mount the /vz/private/101 onto /root1 so that the /root1 is now available to the host node.
You stop the container access to it goes away, but interestingly file system 'space' seem to persist on /root1 in 'invisible' form. You can claim back the space only when you restart the computer.
So, --root option is to make the container file system visible to host node.
2. If I pass --private /root1, I get:
Private area already exists in /root1
Creation of container private area failed
So, I am clearly missing something very basic. In the first place, is what I am trying makes sense? Is it a good idea to set aside a partition for container's root file system? If it is, how can I have a the container setup on a partition available on the host node?
Thanks!
