Hi and Welcome,

I'm afraid you may have to perform an "fsck" on your disk by going in single user mode

OR

Simply try to remount the FS :

mount -o remount <file system name>

Update if that does help.

PS : Please back up any imp. data.

Please post the output of following commands here -

#cat /proc/mounts
#mount
#df
