While I've not seen it, based on reports here on the list, there's apparently a known issue with rsync on btrfs for 3.15 so far. It seems to trigger most often on btrfs' with compression enabled, tho I'm not sure if compression is required to trigger it or if it simply happens more often with it. I'm not sure of the status, but Chris Mason mentioned that he was investigating and trying to reproduce, so they're definitely actively working on it. People seem to have better luck either reverting to the latest 3.14 series kernel for the moment, or updating to the latest 3.16-rc or live- git build, with 3.16 of course getting close to release now. I'd move forward as I know they're always fixing stuff and I routinely test kernel rcs anyway, but Marc Merlin (one of the people reporting this bug), at least, has moved back to 3.14 instead, as he says that works well for him. -- Duncan - List replies preferred.
