Further study, and I suspect that this problem may be from the
upstream provider (i.e. Redhat).
Unfortunately, I can't verify this without reinstalling CentOS4.0 and
recreating the LVM group.
After the problems with the upgrade to 4.2, which broke my LVM group,
(and also broken with a fresh install of CentOS 4.2 from DVD, with
everything formatted but the LVM group), I gave up on this, and
decided to just have the 2 drives be separate filesystems.
Unfortunately, I couldn't mount the second had drive. Got the error
that /dev/hdg1 was already mounted, or /home2 was busy. No, I'm
afraid not. Note, it showed up in /proc/partitions, I could run
fdisk on the drive, repartition t, format it, run fsck on it. Just
not format it).
My speculation is that LVM was failing because I could not mount a
normal partition on the drive either.
Testing this last problem, I decided to just try RHEL WS 4.2. It too
has the same problem.
And the funny part is that, during the actual install, I can mount
and write to the partition from virtual console 2. It is only after
the install that it is failing, which was the same issue with CentOS
4.2, where I could look at the LVM group when present during the
install but not after the install.
2 more notes. I tried the above when SELinux was at both Warn, and
when turned off. Also, when I encountered the problem during a yum
update, it didn't matter whether I booted the original 4.0 kernel or
the 4.2 kernel. So it must have been one of the other packages
Guess I have 2 options. Try Fedora, or install 4.2, live without one
of the drives for awhile, and see if a future upgrade will fix it.
Too bad I can't report it to Redhat. I no longer have a home license
