The two hard disk formed with a LVM2, (100M swap) on hda1 and 19.9G (hda2) + 40G (hdb1). All LVM mounted as / (root). Yesterday, I add a 40G (hdd). Used fdisk with 8e type to format the new 40g (hdd) Used lvm extend command to add +20G /dev/VolGroup00/VolLog00 and +10G /dev/VolGroup00/VolLog01 After that, I wanted to remove the VolLog01 but failed and said it is using. Then I tried to use fdisk again to format the 40g (hdd). After reboot the server, kernel panic even un-plug 40g (hdd). Should I just try to re-create hda2+hdb1's LV with command "lvcreate -n VolLog00 -l VolGroup00" ? I can provide more information if needed. Thanks in advance. Lion
