i am a new bee here
well my problem is i was running Sme server 7.4 on a 150 GB HDD for the last 1 and a half year but few days before after a series of power failure my server failed to boot up.

During the system check on startup I recieved the following:

checking root file system/dev/mapper/mainroot is mounted e2fsck cannot continue aborting

*** and 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 for normal start up):

once i have type the root password i recieve:

(Repair file system) 1 #

At this point i have tried the following commands
man yes
then some command about yes appeared then i typed 'y' in the :
(repair filesystem) 2 # y

then a list of y continuously appears downward now what am i to do?

before this command i tried a lot of commands those where given in the other forums but it didn't work

I need help.
