在准备替换或加装硬盘时,如何得到硬盘信息?
可以用smartctl,hdparm等命令来查询。
在日志中显示硬盘有坏扇区
tail /var/log/messages
-
Mar 1 09:42:55 c1g smartd[1848]: Device: /dev/hda, 2 Currently unreadable (pending) sectors
-
Mar 1 09:42:55 c1g smartd[1848]: Device: /dev/hda, 2 Offline uncorrectable sectors
dmesg中也有错误信息
dmesg
-
ide: failed opcode was: unknown
-
hda: no DRQ after issuing WRITE
-
ide0: reset: success
-
hda: status timeout: status=0xd0 { Busy }
对硬盘做一下健康检查
smartctl -H /dev/hda

检测通过,保险起见还是准备换硬盘。
查看下当前硬盘的型号,可以得到硬盘接口为SATAII,及尺寸大小3.5"
smartctl -a /dev/hda

hdparm也可以得到硬盘型号
hdparm -i /dev/hda

也可以通过主板型号来得知支持的硬盘

/dev/hd~ ==> IDE
/dev/sd~ ==> SCSI、SATA、USB、FLASH
/dev/md~ ==> RAID
至于RAID大小要看系统及文件系统的支持了。
smartctl使用详解:
功能:可以查看生产厂商、型号、序列号、容量、是否支持SMART、开启否
主页:
Centos安装:
yum -y install smartmontools
smartctl
-i 指定设备
-d 指定设备类型,例如:ata, scsi, marvell, sat, 3ware,N
-a 或A 显示所有信息
-l 指定日志的类型,例如:TYPE: error, selftest, selective, directory,background, scttemp[sts,hist]
-H 查看硬盘健康状态
-t short 后台检测硬盘,消耗时间短
-t long 后台检测硬盘,消耗时间长
-C -t short 前台检测硬盘,消耗时间短
-C -t long 前台检测硬盘,消耗时间长
-X 中断后台检测硬盘
-l selftest 显示硬盘检测日志
HP硬盘:
smartctl -s on -d cciss,0 /dev/cciss/c0d0 开启SMART
smartctl -a -d cciss,0 -i /dev/cciss/c0d0 显示所有SMART信息
smartctl -l error -d cciss,0 -i /dev/cciss/c0d0 查看磁盘错误日志

简单说下smartctl:smartd由kernel-utils包缺省安装。用命令 rpm -ql kernel-utils 可以列出kernel-utils包中的文件
它是一个守护进程(一个帮助程序),它能监视拥有自我监视,分析和汇报技术(Self-Monitoring, Analysis, and Reporting Technology - SMART)的硬盘。
主配置文件:/etc/smartd.conf
添加一行/dev/cciss/c0d0 -H -m sys@5iqiong.com
上边的配置表示smartd以静默状态工作,当SMART中报告PASSED的时候不理睬一旦出现Failure
