我的柜子里的机器里有 5 个硬盘。
/dev/sda是 500GB 的 Seagate 硬盘，并且是启动盘。配置
/dev/sd{b,c,d,e}中有 2TB 硬盘raid6。
smartctl显示明显更高的温度（如~140 摄氏度) 位于 RAID 驱动器上，而不是启动驱动器上。
我需要担心吗？
/dev/sdb是/dev/sde新的 Western Digital Black 硬盘（新硬盘=1 周）
/dev/sdc和/dev/sdd5 年前的 Hitachi 硬盘
/dev/sda [SAT], Temperature_Celsius changed from 40 to 39
/dev/sdc [SAT], Temperature_Celsius changed from 142 to 146
/dev/sdc [SAT], Temperature_Celsius changed from 146 to 142
/dev/sdd [SAT], Temperature_Celsius changed from 142 to 146
/dev/sda [SAT], Airflow_Temperature_Cel changed from 61 to 62
/dev/sda [SAT], Temperature_Celsius changed from 39 to 38
/dev/sde [SAT], Temperature_Celsius changed from 107 to 108
/dev/sdb [SAT], Temperature_Celsius changed from 108 to 109
/dev/sdc [SAT], Temperature_Celsius changed from 146 to 150
/dev/sdc [SAT], Temperature_Celsius changed from 146 to 150
/dev/sda [SAT], Airflow_Temperature_Cel changed from 62 to 61
/dev/sda [SAT], Temperature_Celsius changed from 38 to 39

答案1
如果这些是真实温度，那么是的，你应该担心。西部数据黑盘列出的最高工作温度为60 摄氏度（PDF 链接）。日立的规格可能类似。
但是，硬盘达到该温度后仍能正常运行的可能性极小。可能是传感器出现故障，也可能是以华氏度为单位报告的。如果是这样，您应该考虑主动冷却，因为日立硬盘的温度超过 60 度。
