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! =:^) -- Duncan - List replies preferred.
