先安装smartmontools
apt install smartmontools然后用命令查看
smartctl -a /dev/sda
在硬盘没有组raid0 的情况下，用这个命令就可以查看，如果组了raid0，就无法用这个命令查看了
那还另外一个命令：
smartctl -A /dev/sg0这样就能检测到第一块硬盘的信息了
如果要看第二块第三块硬盘，就用
smartctl -A /dev/sg1
smartctl -A /dev/sg2以此类推

smartctl -A /dev/sg0 57123
smartctl -A /dev/sg1 46732
smartctl -A /dev/sg2 30696
smartctl -A /dev/sg3 17690

smartctl -A /dev/sg0 68829
smartctl -A /dev/sg1 58440
smartctl -A /dev/sg2 37579
smartctl -A /dev/sg3 41758
