FC4 Installer and LVM Partitions

[SpaceMunkey]

Does the FC4 Installer recognize existing LVM Partitions? I am thinking of installing it over an Existing Ubuntu linux install, and I would like to reformat and re-use some of the LVM partitions.

I think that when the installer gets to the point of choosing to automatically partition, or manual partition using druid, choose manual. First delete the LVM partitions. Then make new partitions, i.e. /boot=100, /=whatever, swap=ram times 2, /home=whatever. Be sure to de-select the drive which contains the os you want to keep, and that your boot loader (mbr), lilo or grub, is installed on hda. Your other os will show up in your boot loader as second choice..... grub would look something like this....
# cat /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,1)
# kernel /vmlinuz-version ro root=/dev/hda5
# initrd /initrd-version.img
#boot=/dev/hda
default=1
timeout=5

Hope this helps.

I think i didn't make my post clear enough. I'm wanting to preserve the LVM partitions not wipe them out... is Disk Druid intelligent enough to not wipe out partitions when doing it manually, will it pick up on the Physical Volume names and the Logical Group names?

[owakroeger]

I'm sorry, I misunderstood. Yes, disk druid will only touch what you tell it to touch, in manual. It will ignore, thus preserving, anything you tell it to ignore.
