LVM problem <SOLVED>

[Andrew B. Young]

Can anybody point me to a white paper or something that discusses the advantages of using LVM, especially on a single disk PC?  I have not seen the reason to use it on my home (single drive) PC.
Six years ago, using HP-UX, LVM was a nice fit to merge multiple 4GB and 9GB SCSI disks together to from single LVs for chip designers who saved lots of data.  But now, with cheap 200GB IDE drives, that problem went away.

No I have not tried the tool, but I did finally get it working.

I tried rebooting and that left the system locked at the Volume Manager 
stage.  So I rescued booted the system and then chroot /mnt/sysimage and 
then I removed the LV and VG and then I repartioned the HD and then did:

pvcreate /dev/hda1
vgcreate homeVG /dev/hda1
lvcreate -L4G -mhomeLV homeVG
mkfs.ext3 /dev/homeVG/homeLV

and it worked.  So I continued and got all the my VG and LVs up and 
working.   Then I fixed up the /etc/fstab and it rebooted normally!  
Woho, but I'm not totally sure what happened when I was initially 
setting it up.
