无法从Debian上的Seagate磁盘获取智能度量

Question

提到这里这个问题，我也试图把所有属性都去掉，就像在这个博客这里中所解释的那样。

我使用Debian 6作为操作系统，并使用apt安装了smartmontools版本6.3。我的6个磁盘在RAID上。我首先使用命令启用了stats。

sudo smartctl -s on -o on -S on -d megaraid,0 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,1 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,2 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,3 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,4 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,5 /dev/sda

一旦完成，我将使用以下命令来获取所有属性：

smartctl -a -i -d megaraid,0 /dev/sda

但是我没有看到博客文章中告诉我的任何属性。

bash-4.1#     smartctl -a -i -d megaraid,0 /dev/sda

有线索吗?我在这里漏掉了什么？我怎样才能得到智能的度量标准？

Answer 1

不能从RAID数组中提取智能信息。该数组确实有智能信息，以及使其生效的驱动器。

是一个RAID，而不是一个单元(sd0、sd1 / sda1、sdb1等)。因此，从磁盘单元而不是数组中提取信息。
