云服务器 linux文件系统异常an error occurren during the file system check导致服务器启动失败



文件系统宕机，重启后报错，无法启动



处理流程：

1.编辑/etc/fstab将文件系统挂载去掉

# vim /etc/fstab 



#/dev/xvdb /data ext3 defaults 1 2

#/dev/xvdc  /data1 ext3    defaults    0  0



2.重启进入系统，对两个分区进行fsck修复检测(建议使用screen，避免中途被打断)

# screen -S xvdc



# fsck -y /dev/xvdc

fsck from util-linux-ng 2.17.2

e2fsck 1.41.12 (17-May-2010)

/dev/xvdc: recovering journal

/dev/xvdc has gone 510 days without being checked, check forced.

Pass 1: Checking inodes, blocks, and sizes

Pass 2: Checking directory structure

# fsck -y /dev/xvdb

fsck from util-linux-ng 2.17.2

3.检测完磁盘以后打开挂载，并重新挂载，重启系统
