通过 df 查看设备名称,是否可以通过某种方式将其解析为物理驱动器名称,例如供应商/类型。
/dev/sda3 915.4G 34.9G 880.0G 4% /share/HDA_DATA
/dev/sdd3 1.8T 668.1G 1.1T 36% /share/HDD_DATA
我了解到我找到了一些信息系统/块,但我在那里没有找到供应商的类型名称?

我的系统是基于 Linux 的 QNAP NAS,因此情况可能会略有不同。

QNAP NAS 产品运行的固件本质上是一个定制的 Linux 发行版。它非常简洁,具有最少的命令行工具集(其中许多是由 提供的busybox
)。幸运的是,那里有一个不错的实现hdparm
,因此您应该能够查询驱动器,如下所示:
hdparm -I /dev/sda
以下是我从带有“Western Digital RE4 1TB”驱动器的“QNAP TS-239 Pro NAS”获得的输出(输出是逐字的,除了驱动器的序列号,我故意遮盖了它):

Checksum: correct
未明确报告“供应商”和“类型” hdparm
。然而,“型号”是据报道,快速进行网络搜索应该会产生您需要了解的有关驱动器的任何信息。
答案3
大多数现代 Linux 系统都使用乌德夫来管理设备。但并非所有嵌入式设备都是如此。我不知道这个特定设备是否使用udev。
udevadm info -n /dev/sda3 -a
udevadm info -n /dev/sda3 -q property
将打印系统知道的所有内容/dev/sda3
。这与您在 中找到的信息相同/sys
,但 udev 会沿着层次结构向下移动以收集所有数据。
答案4
我也有这个问题。我发现命令:
/sbin/get_hd_smartinfo
当没有 args 运行时打印使用指南。
要将磁盘号连接到设备,请像这样使用:
/sbin/get_hd_smartinfo -d 2 -i 1
按 ctrl-c 终止,它将打印“将文件保存到 /tmp/sdX_smart_zzzzzzz”,其中 sdX 是您的设备。
