hdparm 挂起磁盘：SG_IO：错误/丢失感知数据

我正在尝试暂停两个设置为 RAID1 并带有逻辑卷的 8TB 驱动器。

这些磁盘是相同的，因此我在这里仅显示一个磁盘的输出，但和的输出 (bar Unique ID)相同。/dev/sdc/dev/sdd

hdparm -I /dev/sd{c,d}

我读到上面的内容是我可以开车......

  • 支持电源管理（APM）。
  • 有密码但未启用，驱动器也未锁定或冻结，并且安全计数尚未过期。

hdparm -B所以我尝试使用和来设置降速hdparm -S。

hdparm -B

# hdparm -B /dev/sdc

/dev/sdc:
 APM_level  = not supported

令人惊讶的是，给出的信息表明它支持Power Management feature set，或者它Device-initiated interface power management与此处相关但不受此驱动器支持？

 # hdparm -B 127 /dev/sdc

/dev/sdc:
 setting Advanced Power Management level to 0x7f (127)
SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 04 51 40 7f 21 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
 APM_level  = not supported

找一个线建议SG_IO: bad/missing sense data可以通过暂停来纠正错误，但不能在这里骰子。

hdparm -S

# hdparm -S 127 /dev/sd{c,d}

/dev/sdc:
 setting standby to 127 (10 minutes + 35 seconds)

看起来很有希望，但在检查...

# hdparm -S  /dev/sd{c,d}
  -S: bad/missing standby-interval value (0..255)

其不保留。有关的线。

问题

鉴于上述...

  1. 如何解决SG_IO: bad/missing sense data, sb[]？

  2. 如何正确挂起空闲磁盘？

想要这样做的主要原因有两个，首先驱动器非常吵，其次它们实际上并没有定期使用，因为保持音乐/工作只是定期使用。
