R: Partition....

[Pablo Iranzo Gómez]

	Hi
	LVM stands for: Logical Volume Manager
( http://en.wikipedia.org/wiki/Logical_Volume_Manager_(Linux) )

	With LVM you create a pool of hardrives/partitions that are shown
together (physical volumes) and over it you create volume groups which
contain "logical volumes" (like partitions in traditional schemas).

	One of the advantages is the ability to resize logical volumes within
boundaries of the containing volume group, even online resizing if using
ext3 (growing).

	Using a schema in kickstart for LVM could be:

clearpart --all
part /boot --fstype ext3 --size=100 --asprimary
part pv.3 --size=100 --grow
volgroup Sat --pesize=32768 pv.3
logvol swap --fstype swap --name=swap --vgname=Sat --size=2048
logvol / --fstype ext3 --name=root --vgname=Sat --size=67200

	Which defines a partition for /boot (must be outside LVM right now),
and a physical volume "pv.3" which contains a volume group "Sat".

	Inside that volume group there are two logical volumes, "swap" for
swapping and "root" for "/"

	Regards
	Pablo
