centos重启出现type Control-D to continue【fsck使用】

VMware vSphere克隆异常
/dev/sda2:UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e.,without -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)

可能因为机器异常关机导致无法识别磁盘，需要检测修复。错误中已有提示
处理办法：
1、直接输入密码回车， vi /etc/fstab编辑状态提示只读
2、根据错误提示执行 fsck /dev/sda2 检查修复磁盘(不需要加-y)，如果有其他磁盘(fdisk -l)了也检查下，提示输入y(es)
3、reboot
