i know that this is a good thing, but i've only 1 partition. /boot and /root are in the same partition that i convert from ext3 ti ext4. everything works fine until this morning. I "rebooted" the server many time from the "convertion" but i had never upgrade the Centos before today. with the update the trouble begun! from Installation DVD i can see the /dev/sbd1/ (hd0,0) and with fdisk -l i can see that it's an ext4 partition.
