You seem to be confused about the steps that are required for "getting a directory to store stuff" on Linux. Let me give you a basic workflow: In old fashioned partition setup: a) Get a storage device (hard disk, SSD, FC, iSCSI, ...) -> Result: Device "file" like /dev/sda b) Split the storage device into chunks of wanted size ("partitions") using tools like fdisk, cfdisk, parted === REQUIRED TO BE DONE! -> Result: Device "files" like /dev/sda1, /dev/sda3, /dev/sda15 f) On those partitions, create a filesystem (eg. mkfs.ext3) or swap (mkswap) g) Mount In LVM, you'd do: a) Get a storage device (hard disk, SSD, FC, iSCSI, ...) -> Result: Device "file" like /dev/sda b) Split the storage device into chunks of wanted size ("partitions") using tools like fdisk, cfdisk, parted === COMPLETELY OPTIONAL! -> Result: Device "files" like /dev/sda1, /dev/sda3, /dev/sda15 c) "Declare" the "storage spot" (/dev/sda, /dev/sda3, ...) as physical volumes (pv) using pvcreate d) Create a volume group (vg), using this/these pv(s) e) On a vg, create logical volumes (lv) using lvcreate f) On these/this lv, create a filesystem (eg. mkfs.ext3) or swap (mkswap) g) mount Steps a), f) and g) are identical in old fashioned way and LVM. Step b) is required in partitioning way and optional in LVM setup. It's also identical, that you only create ONE (1) filesystem on any ONE (1) partition or lv. You do *NOT* create two or more filesystems on one partition/lv (it's doable, but *EXTREMELY* unusual). But that's also outlined in the LVM howto... Chapter 11. http://tldp.org/HOWTO/LVM-HOWTO/commontask.html You really should read it...
