startup wrong kernel version

Hello,

I don't understand why not the first kernel version (2.6.32-279.9.1.el6.x86_64) is booted

/etc/grub.conf :

Code:

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.32-279.9.1.el6.x86_64)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-279.9.1.el6.x86_64 ro ...
title CentOS (2.6.32-279.el6.x86_64)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-279.el6.x86_64 ro ...

Kernel version booted (uname -a ) :

Code:

Linux 21.server.tld 2.6.32-279.el6.x86_64 #1 SMP Fri Jun 22 12:19:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

How come ?

I want to add this information :

At bootup when GRUB boot screen is shown, there is only 1 option present, namely :
CentOS (2.6.32-279.el6.x86_64)

So it is normal that this kernel version is started.

Question now becomes : why is there only 1 option present ??

EDIT :

on a server where everything works fine I see (mount) :

/dev/mapper/ddf1_4c53492020202020808627c3000000004711471100001450p1 on /boot type ext3 (rw)

on this server where it does not work, I see (mount) :

/dev/sdb1 on /boot type ext4 (rw)
