Well, if the filesystem in filesystem/diskA and filesystem/diskB is the same (multi-device) filesystem, as the above definitely implies... Tho based on the context I don't believe that's what you actually meant. Meanwhile, send/receive is intensely focused in bug-finding/fixing mode ATM. The basic concept is there, but to this point it has definitely been more development/testing-reliability (as befitted btrfs overall state, with the eat-your-babies kconfig option warning only recently toned down to what I'd call semi-stable) than enterprise-reliability. Hopefully by the time they're done with all this bug-stomping it'll be rather closer to the latter. -- Duncan - List replies preferred. No HTML msgs.
