I have created a file called lab2 and gave access to userID mark, but after su to mark, I  don't have permission to write contents on lab2 file. What am I missing here?

[root@localhost ghuru]# ls  -l lab2
-rw-rw-r--+ 2 ghuru ghuru 0 Mar  9 19:03 lab2

Is this file system should mount with ACL option?

Yes, in your fstab, is it mouted with acl in the options?

If not try doing this

mount -o remount,rw,acl -t ext3 /dev/... /mount/pt

Also for now, try doing chmod 777 lab2, just to make sure

Just an FYI - Sometimes you don't need the acl option in fstab if it is specified in the filesystem's default mount options.  You can check with dumpe2fs:

# dumpe2fs /dev/sda1 | grep mount
dumpe2fs 1.39 (29-May-2006)
Last mounted on:          <not available>
Default mount options:    user_xattr acl
Last mount time:          Thu Feb  3 09:21:52 2011
Maximum mount count:      -1
