Does this mean if there are more I/Os are going on a btrfs file system, copy of entire disk (all disk blocks) gives a stable disk? Just to elaborate more, if btrfs file system is created on 2 disks /dev/sda and /dev/sdb and if I start copying blocks of sda and sdb to sdc and sdc respectively by just opening file handlers of sda and sdb and mounting the new copy via /dev/sdc and /dev/sdd will give consistent file system??
