Hello everyone, I just wanted to ask a short question as I couldn't find a clear answer anywhere on the net, yet:
Is it currently possible to reserve space for a BTRFS subvolume? Following example: I have two subvolumes, one for root and one for home I'd like to reserve 2GB of space for my root volume so even if my home volume fills up, it can never starve my root subvolume. But I don't want to set a fixed limit on my home partition, I want both subvolumes to be able to grow and shrink dynamically. I use that functionality a lot on ZFS-based systems like FreeNAS. In the the web-interface of FreeNAS one can easily configure things like that. If I get it right, qgroups actually already create things like a global reserve. Therefor the functionality seems to be there. Is there a way to use it, just like the limit functionality? Or is it planed? Thanks in advance and regards, Robert
