I see, hoped it would be something quicker. > I saw the pull request with those fixes, so I supsect it didn't go into > 3.9.1 but rather will go into 3.9.2? Probably. However, those patches obviously weren't enough to solve your problem. We don't submit a lot of things to stable, so they are likely to remain the only btrfs related changes in there, which would mean it is unlikely to help with your problem. We can try to debug that further, you can send me / upload the output of btrfs-image -c9 /dev/whatever blah.img built from Josef's repository git://github.com/josefbacik/btrfs-progs.git It contains all your metadata (like file names), data is omitted from the dump. > I probably wait and just do not run the dedup process until I have 3.9.2 > installed.

It's always an alternative to hope for the best :-) -Jan -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
