okay I see. My setup will be unsupported if installed on plain CentOS 7 either way.

I think you asked me about this some time ago. The matrix states: Reliability
Low: big amount of files produce ext4 corruption so often

Why should I use something that tells me it's not reliable?

The /vz partition has also the big advantage of using LVM snapshots and it allows rsync of the container data to another host with less overhead.

Also the need to compress the ploop files does not seem to be something I'm willing to do.
