邮件服务器启动时出错，各位大虾救命啊！！
检查分区时提示错误信息，
/dev/sda5:UNEXPECTED INCONSISTENCY;RUN fsck MANUALLY.
(i.e.,without -a or -p options)
*** An error occured during thefile system check;
*** Dropping you to a shell;
*** when you leave the shell.

Give root password for maintenance(or type Control-D for normal startup)


怎么解决啊？？等着救命啊！！
