OpenVZ "Solved"

Hello,
While we are experimenting, we noticed the disk has been divided into too many 12Gb sections but no idea how and how we can make the containers bigger and equal size?
Here is the output of df -l

We were expecting only number of drives equal to the number of containers, yet we see something completely different.
Here is the containers we have:

How do we make the containers to be equal and use the whole disk at the same time without any useless folders or partitions?
Thanks,

 

I don't know how did you set-up this, but you can increase disk space like so:

Thanks to Mislav and Till,
So does it mean I can increase the size of all containers ignoring those 12gb drives and they will be no problems?
If you do not mind how the virtual drives gets created? and what are they used for?
Thanks again,

 

Thanks Till,
Just ignored the virtual drives and resize my container and it works like magic.
