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:
当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。
