[nflug] centOS 5

[Cyber Source]

Yes LVM does make that handy. But as with the arguement of 1 large 
partition versus many, i.e. /home partition, /var partition, I never saw 
this as something to worry about either. In that if say, you created 
your system with 1 large partition and find your running out of space in 
say /home, you could always add a drive and within your /etc/fstab 
declare your new location for /home (new driver, etc.). Yes, you would 
have to bring the box down but you would to to add another drive anyway, 
unless it was hot swapped. 6 or half a dozen for me.
