哪个磁盘在raid6数组中是坏的
哪个磁盘在raid6数组中是坏的
提问于 2012-05-01 14:48:27
服务器: Ubuntu Lucid
RAID控制器: Adaptec 3805
HP Proliant RAID6 DL180 G5硬件上的8个磁盘
我的kern.log告诉我，我在sdb上有一个错误，如下所示：
[2740390.344436] sd 4:0:1:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[2740390.344439] sd 4:0:1:0: [sdb] Sense Key : Hardware Error [current]

如何在8个磁盘raid6数组中识别哪个磁盘是坏的？

除非我弄错了，否则这些错误告诉您，您的错误还没有被RAID控制器纠正。RAID控制器应该向您隐藏这样的错误。我不认为你有一个简单的磁盘故障。我觉得你有更严重的事情发生了。

假设raid设置中的卷"boot“被识别为sda，"data”被识别为sdb，则系统将告诉您以下内容：
2740390.344436 sd 4:0:1:0：康体局结果: hostbyte=DID_OK driverbyte=DRIVER_SENSE
scsi子系统已经向低级驱动程序(对于adaptec卡)发出了一个没有错误的命令，并且卡响应了一个错误(设置了DRIVE_SENSE)。
2740390.344439 sd 4:0:1:0：康体局感知键:硬件错误当前
这是错误类型(参见scsi驱动程序信息)。
2740390.344442 sd 4:0:1:0：康体局 Add。感觉:内部目标失败
这是司机报告的额外信息，而据我所知，这个信息意味着“没有具体信息”/“不知道出了什么问题”。
2740390.344454 end_request: I/O错误，dev，扇区870177792
错误已到达块层。
正如另一个答案所述:这不是单个磁盘故障，而是整个raid的失败。您应该仔细检查您的数据，并考虑替换raid子系统或至少是控制器。
你应该永远(！)启用raid控制器上的“背景一致性检查”/“被动扫描”/“验证”，以找到无声的损坏，否则在重建时可能会杀死您的raid。
你看到任何文件系统错误了吗？/dev/sdb是否已分区/挂载？

这听起来会很有趣，但是你有没有在服务器的前面看看哪个驱动器有一个错误的LED亮起？(假设驱动器上有LED)
此外，您还可以安装存储管理器软件：http://www.adaptec.com/en-us/downloads/storage_manager/sm/productid=sas-3805&dn=adaptec+raid+3805.html
