with normal partitioning you have
* disks
* partitions (on those disks)
* filesystems (on those partitions)
example
hda (disk)
|
/\
hda1 hda2 (partitions)
| |
ext2 reiserfs (filesystems)
with (linux-)lvm you have
* physical disks (PV) (on a partition or on a whole disk)
* volume groups (VG) (consists of one of more PV:s, think of them as virtual disks)
* Logival volumes (LV) (on those VG:s. think of them as virtual partitions)
So..
hda1 hdc1 (PV:s on partitions or whole disks)
\ /
\ /
diskvg (VG)
/ | \
/ | \
usrlv rootlv varlv (resizeable LV:s, think of them as resizeable virtual partitions)
| | |
ext2 reiserfs xfs (filesystems)
So you need to
1) create a pv
2) create a vg on that pv
3) create lv:s on that vg
4) create a filesystem on those lv:s
5) mount the lv:s
Hope that helps
