AFAIK, if LVM uses 4 disks and one of them fails, the hole file system is lost. With the usual system only the file system on the faulty disk is lost.
That's quite oversimplified, but it's more or less correct, as with
RAID 0 (striping).
On the other hand, you get the disk space of the combined physical
disks, and you can dynamically create and resize logical volumes (=
partitions for your filesystems), given that you're also using a
filesystem on top of those that you can resize dynamically (reiserfs
or XFS can do that even while partitions are mounted).
I've been running quite often into users asking for help because they
don't have enough disk space left, but they have that other or new
disk... can't that be used.. etc... (and yes, I'm a long-time LVM user ;))
cheers
