[linux-lvm] RH8 install - LVM sizing problem



  I am new to LVM and I wanted to use it when I installed a new machine
with RH8.  So going through the install I set everything up with Disk
Druid selecting PV, LV, LVM and gathering all my LV into groups.  I
kept /boot out of the LVM config but everything else is in LVM.  The
layout is shown below.  I have two drives and on the first drive I have
four partitions: dos, /boot, swap and one for /tmp and /var/tmp.  On my
second disk I have one partition (Volume00) and the following
filesystems: /, /usr, /usr/local, /usr/src, /var, /home.
  With plenty of disk space > 100GB I selected an 'Everything' install
and sat back just waiting for everything to complete.  Well, part way
through the install an error displayed saying that I didn't have enough
space on /usr and I needed 1991M more space.  Well /usr was provisioned
for 2GB so I went back and just selected specific packages and tried
again. This time an error displayed saying I needed 1500M more space on
/.  That seemed odd as I had set / to 500M which I thought would be
plenty with a separate /home, /usr, /tmp, /var.  So I went back and did
just a very minimal package selection and tried again.  This time the
installation succeeded.  Finally finished all the additional screens
and it said to have a nice computing experience and then went to a
blank screen and just sat there - dead.  So I pushed the big button and
waited for reboot.  It booted fine and seems to be operating ok but now
I have concerns.

Why was the RH8 installation with LVM needing so much space in / and
/usr?  Was this correct or a bug?

Do I need to expand any of the filesystems to install all the
additional
packages that I was not able to install during installation.

How can I expand the filesystems when LVM commands aren't working?

------------------------------------------------------------------

Wouldn't LVM be running by default when the system boots?

Additional questions:
Is it better to have / outside of LVM maybe in case of LVM problems?

If it is then should any other filesystems be outside with /.
