If
the
machine
panics
at
boot
time,
there
is
a
good
chance
that
you
installed
with
LVM
and
its
got
both
the
drives
into
one
volume.
You
will
need
to
reinstall
that
second
harddrive,
then
work
out
the
process
of
shrinking
the
filesystem
down
to
only
1
drive,
then
remove
the
second
drive.
The
scope
of
this
work
might
be
too
much
for
an
email,
so
I
can
best
point
you
at
the
LVM
HowTo.
There
are
also
some
good
lvm
tips
in
the
CentOS5
docs
(
http://www.centos.org/docs/5/
)
OK this is what I have when I run mount - does it appear that
I have both drives on one volume?:
/dev/mapper/VolGroup00-LogVol00 on /
type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts
