The problem with additional btrfs superblocks has been already reported to btrfs guys: http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg20957.html and I don't see a reply "yep, this is btrfs-progs bug" :-) Karel -- Karel Zak <k...@redhat.com> http://karelzak.blogspot.com -- 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
