为什么我的 RAID 阵列没有重建？

772

昨晚收到通知，服务器上的驱动器出现故障。今天早上去更换它，我们得到以下。阵列的控制器配置报告看起来很好，异常状态Ready for Rebuild。

 ~ # hpacucli controller all show config
Smart Array P400i in Slot 0 (Embedded)    (sn: XXXXXXXX     )
   array A (SAS, Unused Space: 0 MB)
   logicaldrive 1 (341.7 GB, RAID 5, Ready for Rebuild)
   physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK)
   physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK)
   physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 72 GB, OK)
   physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 146 GB, OK)
   physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SAS, 72 GB, OK)
   physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SAS, 72 GB, OK)

逻辑驱动器显示提示，奇偶校验初始化状态：初始化失败：

~ # hpacucli controller slot=0 logicaldrive 1 show 
Smart Array P400i in Slot 0 (Embedded)
   array A
      Logical Drive: 1

         OS Status: LOCKED
         Logical Drive Label: XXXXX     6797

阵列配置（如果有帮助）：

 ~ # /usr/sbin/hpacucli ctrl slot=0 show
Smart Array P400i in Slot 0 (Embedded)
   Bus Interface: PCI
   Slot: 0
   Serial Number: XXXXXXXX

   Surface Scan Delay: 15 secs
   Surface Scan Mode: Idle
   Post Prompt Timeout: 0 secs
   Cache Board Present: True
   Cache Status: OK
   Accelerator Ratio: 50% Read / 50% Write
   Drive Write Cache: Disabled
   Total Cache Size: 256 MB

   No-Battery Write Cache: Disabled
   Cache Backup Power Source: Batteries
   Battery/Capacitor Count: 1

我该如何调试呢？

所有单个驱动器看起来都很好：

~ # hpacucli controller all show config detail | grep Status
   RAID 6 (ADG) Status: Enabled
   Controller Status: OK
   Cache Status: OK
   Battery/Capacitor Status: OK
      Status: OK
         Status: Ready for Rebuild
         Parity Initialization Status: Initialization Failed
         OS Status: LOCKED
         Status: OK
         Status: OK
         Status: OK
         Status: OK
         Status: OK
         Status: OK

我正在调试 hpaducli 和 grsec（还有 mp-SSH 和 Ubuntu）之间的一些不利交互，但我们确实有 hpacucli diag 结果可用，并且隐藏在逻辑驱动器状态标志中的是Rebuild Aborted From Read Error. 这里让我感到困惑的是，重建期间的读取错误如何不会导致标记其中一个驱动器预测性故障，或者更糟，但确实会导致重建停止。
