Core 3 Install Problem

It looks like the Logical Volume Manager or Group is having a problem.
Basically you have the following:
1 PV - physical volume - the basic partiton that gets added to the
LVM. Typically either a standard primary or logical partition.
2 PE -- physical extent -- subset of a PV, every PV has a bunch of
equal sized pieces of disk space called PE's. (Although if you have
differrent LV groups, you can also have differrent size PE's)
3 LV -- logical volume - group of LEs, you can mount something
like /home on an LV.
4 VG -- volume group -- group of volumes (makes sense).
THere are 2 ways to create an LVM Volume Group in RHEL3.
1) set it up during the install (GRAPHICAL MODE) using disk druid; OR
2) it is possible to add them later after the install, (fyi n/a here)
You might try getting around your install problem by actually running
fdisk as early as you can in the install process, maybe from another
terminal window (Ctrl - Alt_ F4 lets say). If you can get the kernel
into ram (ramdisk) then you should be able to switch to a command
prompt and do these things as root.
1. Create a physical volume (PV)
# pvcreate /dev/hdd # for example if your hdd is the fourth
device on the chain
THen you should view it with fdisk to see what you have. If you have
something, try
# pvcreate /dev/hdd2 # creates a new PV on that partition
2. Create a volume group with syntax
# vgcreate volume_group_name /dev/hdd2 /
add to the size of it with the command
# vgextend volume_group_name /dev/sda
3. Create a logical volume with the syntax
# lvcreate -l number_of_PEs volume_group_name -n logicalvol
This will create a device called /dev/volume_group_name/logicalvol
ALso make sure that /etc/fstab looks like the following:
LABEL=/home/marc /home/marc ext3 defaults 1 2
Also you should do
# e2label /dev/volume_group_name/logicalvol /home/marc
which creates a label for the directory.
All for now, I hope that helps somewhat.
Cheers
