umount the partition.  If you can't umount the partition go to single user
mode, and umount it.  Then fsck the partition.  

However, I just have to ask why you're using an ext2 partition these days. 
At _least_ convert it to ext3 - it's just a matter of adding the journal. 
Then if your filesystem doesn't get properly shut down, the journal will be
processed on restart to keep your filesystem clean.
