It's REALLY handy if you use more than just one huge
partition, and need more space.. (lvextend,
IF you have plain old partitons, like sda1. sda2. sda3
and so forth, and sda1, or sda2 is full, you're
pretty well screwed, however if you had setup with
LVM and if you have free PE's (physical extensts), u
can easily add more, in most cases without even
needing to reboot or taking anything down...
Also with LVM, if you have a drive that is starting to
go (i.e. smartd errors), u can pop in another drive,
add it to your VG, issue a "pvmove" to move all the
data from one drive to the other, while the system is
running, then "vgreduce" the old drive out, and set it
on the desk as a paperweight, all while the system is
live (assuming hotplug scsi/sas, otherwise a powerdown
for the drive insertion/removal)
