服务器意外断电,无法启动故障处理

今天服务器意外断电,电源恢复之后重启时却报错,无法启动!报错信息如下所示:

 整理一下报错信息:

checking filesystems    #从这里就就可以看出来,应该是文件系统出了问题
/contians a file system wite errors, check forced
Error reading block 145817602(Attempt to read block from filesystem short read)while geting mext inode from scan. #在扫描数据块时候出了毛病
/:UNEXPECTED INCONSISTRENCY;  RUN fsck MANUALLY.
(i.e,withiout -a or -p options)
                                            [FAILED]
*** An error occurred during the file system check
*** Dropping you to a shell; the system will reboot
*** when you leave the shell,
Give root password for maintenance (or type Control-D to continue)   #让我们手工输入密码

猜测原因:

Linux系统被强行关闭或重新启动,文件系统便有可能受损,系统会自动检查并修复文件系统;但文件系统未能自动修复,画面便会出现上述讯息。需要手动修复

修复步骤

1. 当出现上述错误后,首先看的提示“Give root password”,首先想到的是输入超级用户的密码。

2. 由于知道系统所有的分区都ext格式的,所以e2fsck -f  把三个分区都检测修复了一下,输出以下下信息


e2fsck 1.32 (09-Nov-2002)

/boot was not cleanly unmounted, check forced

Pass1: Checking inodes, blocks, and sizes(pass1检测完,有的会需要你输入Y,按照输入就行)

Pass2: Checking directory structure
Pass3: Checking directory connectivity
Pass4: Checking reference counts
Pass5: Checking group summary information
/boot: *****FILE SYSTEM WAS MODIFIED*****
/boot: 53/26104 files (13.2% non-contiguous), 27316/104391 blocks

3,检测完成后,提示让重启,重启之后,正常进行系统,问题解决。
