Yes, I have to idea in mind. 

1- Using ZFS 
I have to try how it looks with LXD/LXC. I wanted to give a try to btrfs .
With ZFS , are you using quotas ? Can you tell me what "df -h" looks into your container ?
With btrfs , the container see the disk size of the host, so you don't know how much space you are using, it's was not the best anyways.

2- LVM
A the beginning, it's the solution I was using. Finally it was not that bad. 
By a script to create containers, I was doing :
- Create a new LVM  Volume
- Mount the volume
- Install the container with "dir path" 

So in the container you have one disk, it's the full size of the volume and act like a real disk including volume size information 

Cordialement,


Benoît

Hmmm that doesn't sound prommising then :'(

Anyway for my local server I use ZFS on Linux (Ubuntu 16.04). Maybe 
that's something for you too?
I don't use ZFS on my VPS, cause it doesn't have enough RAM (just 1GB)

Cheers,
Sjoerd
