查看centos服务器硬盘状态信息

windows下有HDTune可以查看磁盘的状态，防止磁盘挂掉才会自己知道，CentOS下有SMART (Self-Monitoring, Analysis and Reporting Technology System) 同样对磁盘做状态检测
下面以dell R720服务器举例，/dev/sda是1T的scsi接口普通硬盘，/dev/sdd 是三块盘做的raid5
# df -h #查看磁盘的名字
# dmesg |grep sdd #查看开机信息里面的磁盘info
sd 0:2:0:0: [sdd] Attached SCSI disk
# hdparm -I /dev/sda #查看磁盘硬件信息、开启的功能等,信息特别详细
下面用smart查看磁盘的状态：
# yum install smartmontools //安装SMART
# smartctl -H /dev/sdd //磁盘健康状况查看
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-3.10.56-11.el6.centos.alt.x86_64] (local build)

SMART Health Status: OK
# smartctl -A /dev/sda 或者 smartctl --all /dev/sda #硬盘的smart信息
# smartctl -a /dev/sdd

Device does not support SMART
Error Counter logging not supported
Device does not support Self Test logging
这里提示Device does not support SMART，所以按下面方式查看
查看raid5中第一块磁盘的状态
# smartctl -a -d megaraid,0 /dev/sdd
同样查看第二块、第三块磁盘的状态，根据自己的监控情况，加速nagios、zabbix报警
# smartctl -a -d megaraid,1 /dev/sdd
# smartctl -a -d megaraid,2 /dev/sdd
