RE: possible bug in kickstart with RHEL4 and %pre scripts using LVM



My that looks familiar ;)

What happens if you don't "calculate" the number of drives.  In other
words, change to this:

let numd=1 

This can help narrow down if that is really what the problem is.

Subject: possible bug in kickstart with RHEL4 and %pre scripts using LVM

Hi All,

Ran into what I believe is a bug. It looks to be in the %pre section.

Background:

Running CentOS release 5 with cobbler 0.5.2. I have a kickstart file for
installing RHEL 4.5 (see below).

I have a %pre section in the kickstart file that defines partitions:


# Magically figure out how to partition this thing %include
/tmp/partinfo

%pre
# Determine how many drives we have
set $(list-harddrives)
let numd=$#/2
d1=$1 # This is the device of disk 1
d2=$3 # This is the device of disk 2, etc.
S1=$2 # This is the size of disk 1
S2=$4 # This is the size of disk 2, etc.

# This would be a partition scheme for two or more drives if [ $numd -ge
2 ]; then cat << EOF >> /tmp/partinfo part /boot --fstype ext3
--size=100 --ondisk=$d1 --asprimary part /boot2 --fstype ext3 --size=100
--ondisk=$d2 --asprimary part swap --size=512 --ondisk=$d1 --asprimary
part swap --size=512 --ondisk=$d2 --asprimary part raid.01 --size=1
--grow --ondisk=$d1 part raid.02 --size=1 --grow --ondisk=$d2 raid pv.01
--fstype "physical volume (LVM)" --level=RAID1 --device=md0
raid.01 raid.02
volgroup internal_hd pv.01
logvol / --fstype ext3 --name=slash --vgname=internal_hd --size=1 --grow
EOF

else

cat << EOF >> /tmp/partinfo
part /boot --fstype ext3 --size=100 --ondisk=$d1 --asprimary part swap
--size=1024 --ondisk=$d1 --asprimary part pv.01 --fstype "physical
volume (LVM)" --size=1 --grow --ondisk=$d1 volgroup internal_hd pv.01
logvol / --fstype ext3 --name=slash --vgname=internal_hd --size=1 --grow
#part / --fstype ext3 --size=1 --grow --ondisk=$d1 EOF

fi


This pre script shows the following errors on vt3:
* Running kickstart %pre script(s)
let: arith: syntax error: "numd=2/2"

let: arith: syntax error: "numd=2/2"

[: 2: unexpected operator

* All kickstart %pre script(s) have been run
* Exception parsing ks.cfg: Defined PV partition pv.01 multiple times


In this particular case I have only one (logical HW RAID) drive and the
/tmp/partinfo is created with the lines contained in the else clause
from above.

The error about partition pv.01 causes kickstart to fail and die :-(

Please see the full kickstart file below.

I should note that if I place the part info from the else clause outside
of the %pre section (i.e. just create a static partition declaration in
the kickstart file) then everything works as expected.

Any ideas? I'm stumped.

Cheers,
Harry
