Difference between LVM and Ext3

Could any one please give me a clear view on ext3v and LVM?

Which one would be better on any case?

Any thoughts would be welcome

LVM is software-based storage aggregation technology.
Ext3 is a filesystem.

There is no "which is better?" as they are completely different things.

To add on to zordrak's (correct) explaination above:

LVM aggregates your disk/s in terms of the devices that are presented to the OS.

Whether you have an ordinary partition; or an LVM logical volume; you need to format a filesystem on this; in order to mount it and thereby use the space.

ext3 is a type of filesystem that you can format on a device.

in short...

1. ext3 is a type of filesystem (there are many from msdos, hpfs, ext2 and so on)

2. lv is a structure of volumes each of which is to be formatted with some filesystem type (like ext3, ext2 etc...)

I hope it helps
