Disk model: Samsung SSD 970 EVO Plus 2TB我在 Linux 服务器 ( ) 上配备了6 个 SSD 磁盘 ( ) Rocky Linux 9.1。使用两张 m.2 到 PCIe 转换器卡，一张可容纳 4 个磁盘，另一张可容纳 2 个磁盘。所有磁盘都格式化为 XFS 并作为单独的磁盘安装（根本没有 raid）。它们运行良好，直到系统重新启动。之后，所有磁盘都无法挂载并显示相同的错误：
[ 76.534528] XFS (nvme0n1): Mounting V5 Filesystem
[ 76.535327] XFS (nvme0n1): totally zeroed log
[ 76.535859] XFS (nvme0n1): Corruption warning: Metadata has LSN (1:23691) ahead of current LSN (1:0). Please unmount and run xfs_repair (>= v4.3) to resolve.
所以我尝试了xfs_repair 没有 -L，结果是
Sorry, could not find valid secondary superblock
Exiting now.
谁能给出一些提示，如果数据仍然保存或不保存？如果是这样，我应该尝试什么？我不是专业的 IT 人员，希望这些信息足够，但如果您给出指示，我很乐意提供更多信息。谢谢！
