求助数据恢复

汤汤

X86 、fnOS 1.1.26

物理机

公网 域名反代访问
Edge107.0.1418.24 、Chrome 148.0.7778.168

BUG 现象：
5.4日通过手机从1.1.26升级系统但显示失败后后存储空间不能访问，硬盘显示未使用。

raid5阵列3*2.7T。升级后存储空间不显示或ai协助出现后但无法挂载。
系统升级失败后又重装回1.1.26系统。系统盘格式化过。之后多次尝试ai 协助恢复全失败

ai提示
BTRFS 元数据：严重损坏
超级块备份：全部失效

⚠️
数据抢救遇到严重障碍
btrfs restore 无法识别文件系统结构，说明 chunk tree 损坏程度超出预期，备份超级块也已失效。

三块硬盘5.4号之后未格式化，也未在进行写入操作，ai提示数据文件 应该没问题
