It looks like btrfs isn't handling errors coming back from the block layer - at that point it's just called btrfs_relocate_chunk().. So my guess is that the rebalancing code is naive and assumes the drives are the same size - but I can't quite follow what the code above that BUG_ON() is doing to verify that.. Chris M. ? cheers!
