SSD 无法安装:坏超级块但没有坏块:写入错误

SSD 无法安装:坏超级块但没有坏块:写入错误

刚刚注意到我正在使用 SDD 作为 SSD。已更正

我需要帮助解释这种情况。/dev/sda是一个备份的数据磁盘,并且具有可重现的数据,因此这不是系统关键,但我想避免恢复/重建数据的工作,其中一些数据将非常耗时

可以恢复/修复吗?

如果可以,怎么办?如果我擦除磁盘以便重新使用,其可靠性如何?

摘要(详细报告如下):

  • 无法安装:坏超级块
  • badblocks 未发现坏块
  • smartctl 报告没有错误
  • fsck 无法设置超级块标志
  • fdisk 显示干净分区
  • dmesg 显示写入错误
  • parted 显示 1 TB 驱动器中有 792 GB 可用空间

挂载 ssd 失败,如下所示:

 [stephen@meer ~]$ sudo mount /dev/sda1 /mnt/sda
 mount: /mnt/sda: can't read superblock on /dev/sda1.
        dmesg(1) may have more information after failed mount system call.
 [stephen@meer ~]$ 
 

但 badblocks 没有发现坏块

 [root@meer stephen]# badblocks -v /dev/sda1              
 Checking blocks 0 to 976760831
 Checking for bad blocks (read-only test): done                                                 
 Pass completed, 0 bad blocks found. (0/0/0 errors)

但smartctl没有发现错误

 [root@meer stephen]# smartctl -a /dev/sda

答案1

我不知道你用这张磁盘做了什么,但这真是疯狂的数字!查看 SSD 的输出:

  • 1470 小时(61 天)
  • 执行了 4312400063 (2.0GiB) 块擦除
  • 163210068006 (76TiB) 介质写入。

61 天内的写入速度恒定为每秒 16MiB。

我想你可能遇到了内部 NAND 故障。您可能无法取回数据。

我建议您最好的解决方案是使用某种形式的 raid 镜像来缓冲多个磁盘之间的错误。

理想情况下,可以使用两个不同寿命和/或不同生产批次的磁盘来尝试在多个磁盘之间分散错误和故障的分布。

澄清一下,我认为在很短的时间内写入量异常高。您需要将其考虑到您使用的存储设置中。
