提到问题这里，我也试图获取所有属性，正如本博客中解释的那样这里。
我使用 Debian 6 作为操作系统，并使用 apt-get 安装了 smartmontools 版本 6.3。我的 6 个磁盘位于 RAID 上。我首先使用以下命令启用了统计信息
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
完成后，我将使用以下命令获取所有属性：
smartctl -a -i -d megaraid,0 /dev/sda
但我没有看到博客文章中所说的任何属性。
bash-4.1# smartctl -a -i -d megaraid,0 /dev/sda
smartctl 6.3 2014-07-26 r3976 [x86_64-linux-2.6.32-5-amd64] (local build)

有什么线索吗？我在这里遗漏了什么？如何获取 SMART 指标？
答案1
您无法从 RAID 阵列中提取 SMART 信息。阵列确实有 SMART 信息，即组成阵列的驱动器。
Dev sda 是 RAID，而不是单元 (sd0、sd1 / sda1、sdb1 等)。因此，请从磁盘单元（而不是阵列）中提取信息。
