hi, i'm used to manual partition and format disks before installing the O.S. but with centos 5 this results in an unbootable system. Usually, to manual partition the disks I use the installation disk in recovery mode.. The partition schema I choose was: /dev/sda1 /boot /dev/sda2 swap /dev/sda3 LVM PV inside the LVM VG I created the following LV / /var /home /tmp Then I formatted all the partitions with ext3 (doing some tuning on ext3 parameters) After I had partitioned and formatted the disk I booted from the installation CD and I installed centos 5 without any error. The installed system was not able to boot at all , the boot process ends with a kernel panic when trying to mount the root partition. On the same hardware Itryed to install centos 5 choosing the deafult auto partition option and the resulting system was ok. What's wrong ? What did i miss ?
