RAID1 的所有驱动器的 SMART 短离线测试永不结束

RAID1 的所有驱动器的 SMART 短离线测试永不结束

我遇到了一个奇怪的情况。在低流量服务器中使用了大约三年后,RAID1 中的两个三星驱动器中的一个昨天发生故障:

Personalities : [raid1]
md0 : active raid1 sdb1[2](F) sda1[0]
      732572608 blocks [2/1] [U_]

由于 smartd 没有报告任何内容,我检查了智能属性,与 sda 相比,sdb(失败)上唯一不同的可疑读数是:

sda:
191 G-Sense_Error_Rate      0x0022   252   252   000    Old_age   Always       -       0

sdb:
191 G-Sense_Error_Rate      0x0022   098   098   000    Old_age   Always       -       27650

服务器机架中的 G-Sense 出现错误?可能是传感器出现故障?

但还有另一种有趣的解读两个都驱动器:最新的短暂离线测试为“中断(主机重置)”,如果我开始新的测试(例如使用)smartctl --test=short /dev/sda,则选择性自检日志显示:

SPAN  MIN_LBA  MAX_LBA  CURRENT_TEST_STATUS
   1        0        0  Self_test_in_progress [90% left] (0-65535)

然而,这场短暂的考验永远不会结束,甚至几个小时后情况仍然一样——两个都驱动器。这可能是驱动器上的固件错误吗?还是控制器出现故障?

以下是两个驱动器的完整转储,每个驱动器都运行了简短的自检:

/dev/sda:

控制器错误似乎可能出现在这里。在您花费太多时间之前,我建议您重新安装所有电缆。随着时间的推移,可能会出现松动并导致问题。

另外,您提到了 smartd...您在尝试运行自检时是否禁用了它?这可能会干扰手动测试。

有没有dmesg关于为什么 sdb 被视为失败的信息?两个驱动器似乎都将其健康状况报告为“已通过”,并且我不相信 mdadm 实际上使用任何 SMART 数据来确定驱动器的健康状况。
