Btrfs分区无法挂载，检测到块组与Chunk不匹配错误求助

我现在碰到个棘手的问题：我的Btrfs分区死活挂载不上，就算用SystemRescue里的工具（btrfs-core v6.6.3版本）尝试也没用。

执行mount命令时直接返回了一个通用错误，查看dmesg日志能看到这些报错信息：

BTRFS info (device dm-0): block group 828547006464 len 35185445830656 mismatch with chuck 828547006464 len 10737341824
BTRFS info (device dm-0): failed to read block groups -117
BTRFS info (device dm-0): open_ctree failed

之后我运行了btrfs check来检测分区，得到的结果如下：

[1/7] checking root items
[2/7] checking extends
Block group[8285470064664, 35185445830656] existed .
