Question

当我尝试在已安装的硬盘上使用“ls”时，我的系统出现了I / O错误。

我正在使用

hadoop@hbase1:/hddata$ uname -a
Linux hbase1 3.8.0-29-generic #42~precise1-Ubuntu SMP Wed Aug 14 16:19:23 UTC 2013 x86_64    x86_64 x86_64 GNU/Linux

最后几行dmesg

hadoop@hbase1:/hddata$ dmesg | tail

Answer 1

Buffer I/O error on device sda1, logical block 0

这种事情表明即将发生的硬件故障。我会尽你所能将你需要的所有内容备份到其他地方，并在驱动器无法修复之前更换驱动器。

ls：读取目录。：输入/输出错误
