Hi,From what I remember,it depends on the use of the disk. If its a boot disk,
you have to have one DOS boot partition to start the system. However, if the
disk is a second disk, then the whole disk can be folded into LVM.
Thanks

Hi
For virtual servers it is nice to usethe whole disk for LVM instead of creating
a LVM partition on the disk.Then you can just increase the size of the disk in
VMware and later extendthe file system instead of having to add another disk
and extend.
Is it possible to use this setup inthe kickstart? What syntax do one use if it
is possible?
If I have done it manually it whouldhave been like this:
pvcreate /dev/sdb (instead of usinga LVM partition called /dev/sdb1)
vgcreate DataVG /dev/sdb
lvcreate -n DataLV -l 100%FREE DataVGDataLV
At the moment I have the following partitioningscript in my kickstart file for
RHEL6/7 as a pre script:
DISK_TYPE=$(parted -s /dev/sda print|grep Model | awk '{print $2}')
echo "Disk type = $DISK_TYPE"
if [ "$DISK_TYPE" = "VMware"]
then
echo "This is a VMware server,disk type=$DISK_TYPE"
cat > /tmp/partitioning.cfg <<EOF
part /boot --fstype="xfs"--size=1024 --ondisk=sda
part pv.01 --size=10240 --grow --ondisk=sda
volgroup VGos pv.01
logvol / --vgname=VGos --name=LVroot--size=10240 --grow
logvol swap --vgname=VGos --name=LVswap--recommended
part pv.02 --size=1000 --grow --ondisk=sdb
volgroup VGdata pv.02
logvol /usr/users --vgname=VGdata --name=LVhome--size=20480
logvol /app --vgname=VGdata --name=LVapp--size=1000 --grow
EOF
else
echo "This is a Physical server,disk type=$DISK_TYPE"
cat > /tmp/partitioning.cfg <<EOF
part /boot --fstype="xfs"--size=1024 --ondisk=sda
part pv.01 --size=10240 --grow --ondisk=sda
volgroup VGos pv.01
logvol / --vgname=VGos --name=LVroot--size=10240 --grow
logvol swap --vgname=VGos --name=LVswap--recommended
logvol /var --vgname=VGos --name=LVvar--size=20480
EOF
