Glad the big-file-move-off seems to have worked for you, and thanks for 
confirming that moving them off did indeed solve your conversion 
blockers.  Evidently btrfs still has a few rough spots to iron out when 
it comes to those big files. =:^(

Please confirm when all big files are moved back on, too, just to be sure 
there's nothing unexpected on that side, but based on the conversion-from-
ext* reports, I expect it to be smooth sailing.  Btrfs really does have a 
problem with large files existing in large enough extents that it can't 
really handle them properly, and once they are off the filesystem 
temporarily, generally even moved off and back on, it does seem to break 
up the log jam (well, in this case huge-extent-jam =:^) and you're back 
in business! =:^)
