It's the tools that work on the unmounted filesystem, btrfs check, btrfs restore, btrfs rescue, etc, where the userspace code does the real work, and thus where being current and having all the latests userspace fixes is vital. If you can't mount writable, you can't balance. -- Duncan - List replies preferred. No HTML msgs. "Every nonfree program has a lord, a master -- and if you use the program, he is your master."
