Discouraging mounting lvm-thin

[Baptiste M]

Hello,

I am currently transitioning from 3.4 to 4.4 on online.net. Of course, their image use a full ext4 partition so I work from a debian install. As I like lxc and snapshot, I go with thin-lvm

I read here (https://pve.proxmox.com/wiki/Installation:_Tips_and_Tricks) that mounting the thin-lvm is not recommanded, I don't understand why?

What problem will I face with "mounted" thin-lvm partition?

Thanks!

When using a (thin-)lvm storage for lxc containers it is never mounted (in the host). If you mount a (thin-)lvm on the host it must contain a filesystem (e.g. ext4), in that case you can use it as "directory" storage in Proxmox VE, if such a storage for lxc containers snapshots are not possible.

Thanks for your answer.

That what I understood playing with the latest version ! Seeing how it works, it makes much more sens to me and I really appreciate the benefits.

I just wrote a small script that allow me mounting VMs disk when I need and a wrapper around lxc-attach that feel like "vzctl enter" and everything is perfect.
