查看磁盘信息

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

  1. Mar  1 09:42:55 c1g smartd[1848]: Device: /dev/hda, 2 Currently unreadable (pending) sectors
  2. Mar  1 09:42:55 c1g smartd[1848]: Device: /dev/hda, 2 Offline uncorrectable sectors

dmesg中也有错误信息
dmesg

  1. ide: failed opcode was: unknown
  2. hda: no DRQ after issuing WRITE
  3. ide0: reset: success
  4. hda: status timeout: status=0xd0 { Busy }

对硬盘做一下健康检查
smartctl -H /dev/hda

  1. smartctl version 5.33 [i386-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen
  2. Home page is http://smartmontools.sourceforge.net/
  3.  
  4. === START OF READ SMART DATA SECTION ===
  5. SMART overall-health self-assessment test result: PASSED

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
