Description of problem:
The RH instller crashes in two different circumstances on my system that uses 3 hard drives, both seem to be related to a bug in
- putting a LVM volume on one disk, and a software raid using two other disks, or
- putting a LVM volume on one disk, and second LVM volumne that spans two other disks.
Here's my configuration: Pentium 4 machine with 3 hard drives; one on one ide bus, and two on another ide bus.
Here are the details for the two scenarios.
When I get to disk druid, I create these partitions on hda: /boot partition (150MB), /swap partition (2GB), and an LVM partition
"Volume00" (using all remaining space on hda). Then I put three logical partitions on within Volume00. Next, I create a software raid
partition on hde (whole disk) and a software raid paritition on hdf (whole disk), and tie these two together as /home in a software
raid. The installer then fails later in the install process. If I try to re-run the installer, it *always* generates an exception when
disk-druid starts (I can no longer get to the disk druid step in the installer). I get prompted to put in a disk to download the dump
below). The only way I can recover from this is to use another program to wipe the disks clean.
When I get to disk druid step, I create the same partitions on hda as in Scenario 1 above, including the LVM volume. I create an
volume on hde that uses the whole disk, and an LVM volume on hdf that uses the whole disk. Then I create a logical volume that
combines these two lvm volumes. When I get to the part of the part of the install script where it is just about to start installation, the
installer crashes, and prompts me to put in a disk to capture the dump (see below)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
See description above.
Actual Results: Installer crashes after creating an LVM partition on one disk, and a RAID volume that uses two other disks;
Installer also crashes after creating an LVM partition on one disk, and an LVM that uses two other disks.
Expected Results: Should be able to create the parititions described above. Installer shouldn't crash.
I have two files containing dumps from these exceptions, but I see no way to upload these using this bugzilla webform.

I've uploaded the exceptions I describe in the bug report
I could not reproduce these issues - vgscan is known to fail if fragments of
data on the disk appear to be LVM. It is not a robust program.
We have changed things to handle vgscan failing more gracefully and this should
address a problem like yours in the future.
