Q: BTRFS <> comments/thoughts how it is working in proxmox - anyone - ?

Thats... not really a fair comparison. You need to have an equivalent amount of contiguous space ELSEWHERE to make this work; fragmentation is really one of zfs's Achilles heels. BTRFS has another feature no one mentioned (I suppose I did lol) dedup is actually usable, and can be done asynchronously so it doesn't impact performance or require ungodly amounts of RAM.

I like btrfs. I really wish it would get the development attention it needs to really excel, but alas that isnt happening.

Didn't know dedup was usable and didn't require large amounts of ram as well. How well do dedup work with virtual machines?

I dont actually know. Like I said, I never used BTRFS for production, and under lab conditions I wouldnt present any findings as authoritative as the loads are largely synthetic. For filesystem use it works relatively well.
