[lxc-users] Btrfs - Disk quota and Ubuntu 15.10

[Benoit GEORGELIN - Association Web4all]

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,

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,
