LVM is very nice if you need more than 1 partition on your RAID storage.
YOu then just create one large RAID set, and partition it with LVM, its
really very handy.
Also LVM could even combine more one one physical storage into a Volume Group.
Of course you could do that with RAID too, but with LVM you could do it after
you�ve created you�re filesystems. E.g you buy today a 100 GB Raid for you�re
videoservice, and next year add a second RAID set with for example 1 TB. LVM
would allow you to combine both RAID sets into on Logical Volume. Of course
this needs a working ext2resize. And of course I would not recommend such a
large Logical Volume without an Journaling Filesystem.
Sincerely,
Klaus
