Hello, It seems Btrfs Chunk Tree is damaged, so you can not mount Btrfs filesystem any more.
However, you can try the latest Btrfs-progs, Miao Xie implements chunk tree recover function. The url is: git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git you can try it: btrfs chunk-recover -v <dev> This is Time-consuming, because it will scan the whole disk. And also, please catch output of processing(this is helpful to us if the recovery fails, -v option enable this). Thanks, Wang -- 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
