我在Synology DiskStation的驱动器上遇到问题。 我在/ var / log / messages中看到以下错误消息：
ata6.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata6.00: failed command: SMART ata6.00: cmd b0/d0:01:00:4f:c2/00:00:00:00:00/00 tag 0 pio 512 in res 40/00:01:06:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) ata6.00: status: { DRDY } 我不知道这是什么意思，但似乎有一个问题，由于100％IO等待，我的磁盘arrays不可用，所以我认为这可能是罪魁祸首。
然后，我去了smartctl -a上运行，得到如下输出结果：

我不明白这个输出是怎么说的。 有人能帮我一把，为我解密吗？ 我看到它说testing通过了，但是我也看到了一些关于“预失败”，“老年”的事情，表中的值似乎大于阈值。
这个驱动器是否正在死亡？
随着19,440个重新分配的部门，你的驱动器已经是最后的腿了。
5 Reallocated_Sector_Ct 0x0033 085 085 010 Pre-fail Always - 19440
这通常是我在旋转防锈盘上看到的第一个属性。 除零原始值以外的任何内容都是一个潜在的问题，因为这意味着磁盘表面的一部分在内部已经被标记为坏，并且现在已经为坏扇区填充了保留空间。 随着大量重新分配的部门，你会看到性能问题，并最终丢失数据。
在SMART实际上将其显示为失败之前，它必须有更多的坏扇区，但是您可以确定它现在失败了，应该被replace。
事实certificate，这是驱动器。 只要我从arrays中取出驱动器，即使它处于降级模式，arrays也立即可用。
