Hello everybody, I'm no developer, just a simple user. I use btrfs as the root filesystem on my laptop. I use VirtualBox. Every VB disk lives in a separat btrfs subvolume. I use btrfs snapshots for backup and to clone VB VMs.
I wonder what happens when I defrag a file that is part of multiple snapshots? Will all instances of this file be defragmented, or will the file get its own fresh copy? If it is important, my system is a 64bit ubuntu 10.10 and the filesystem is mounted with the option compress. If it helps, I would consider to upgrade to 11.04. BTW: what is the difference between defrag and balance ?
