I currently have a personal nas running ubuntu server, but I’m considering moving it to opensuse leap. I’ve dabbled a bit with leap inside of virtual machines, but maybe someone more experienced with it can give me a more complete opinion. Also, is btrfs worth getting into, or can I just use ext4 and loose out on nothing (except snapshots)?
Take in mind that lot of btrfs features need to be disabled (noCOW flag) for VM workloads to have acceptable performance. I usually just take the hit in performance if i need a VM (it’s not my primary use), but it is there and is noticeable.
