所以我们把另一个带有工作OS的驱动器放在那里,然后我们尝试在旧驱动器中安装分区.
大多数分区都安装正常,除了一个：/ var分区,我的MySQL表所在的分区.
当我尝试安装那个时,我用dmesg看到这些错误：
sd 0:0:1:0: Unhandled sense code
sd 0:0:1:0: SCSI error: return code = 0x08100002
Result: hostbyte=invalid driverbyte=DRIVER_SENSE,SUGGEST_OK
sdb: Current: sense key: Medium Error
Add. Sense: Unrecovered read errorInfo fld=0x4a47e
JBD: Failed to read block at offset 9863
JBD: recovery Failed
EXT3-fs: error loading journal.
有没有办法可以恢复该分区中的数据？

根据要求,tune2fs -l / dev / sdb2的输出为：

正如@Hartmut所建议的那样,我使用以下结果运行fsck.ext3 / dev / sdb2：
e2fsck 1.39 (29-May-2006) /var1: recovering journal /var1: Attempt to read block from filesystem resulted in short read while reading block 11931 JBD: Failed to read block at offset 9863 fsck.ext3: No such device or address while trying to re-open /var1 e2fsck: io manager magic bad!
解决方法
您将需要第二个空白硬盘驱动器,至少与发生故障的驱动器分区一样大,以执行此磁盘的任何类型的恢复.您还需要一个目标来复制恢复的文件,所以我们称之为第三个空白硬盘,网络文件共享等.
一般的恢复过程将是：
>使用dd conv = noerror或更好的dd_rescue将失败的分区复制到新驱动器.这可能要花点时间.
>对副本执行所有进一步操作在此我假设您已将/ dev / sdb2复制到/ dev / sdc2,并且您将文件恢复到/ dev / sdd2.
>由于期刊已损坏,我们将删除它：
tune2fs -O ^has_journal /dev/sdc2
>现在完成设备的fsck.这可能要花点时间.
e2fsck /dev/sdc2
mount -o ro /dev/sdc2 /mnt/baddrive mount /dev/sdd2 /mnt/recoveredfiles cp -av /mnt/baddrive/* /mnt/recoveredfiles
>在任何情况下都不应该再次使用原始磁盘.更换它(在保修期内,如果它仍在保修期内).
