Creating Filesystem using DD for LVM
I created a new filesystem using dd and mounted:

I have a filesystem /FAW with 1Terra space
Code:
/dev/sdb1            1151331444  24742604 1068104612   3% /FAW



Steps I followed to create a new filesystem
Code:
# dd if=/dev/zero of=/FAW/vms/linux_vm/disk2.img bs=1 count=1024 seek=500G
# mke2fs disk2.img 

# mount -o loop disk2.img /FAW/xen_vm/

Now df -k output is :
==============

Code:
/FAW/vms/linux_vm/disk2.img
                     516061624     71448 489775776   1% /FAW/xen_vm


I want to be able to add the above disk2.img partition to pvcreate lvm which does not recognize.

Can someone tell me how i should convert it to filetype recognised by LVM.

NAME

       filesystem - event signalling that filesystems have been mounted

SYNOPSIS

       filesystem [ENV]...

DESCRIPTION

       The  filesystem	event  is  generated by the mountall(8) daemon after it has mounted all filesystems listed in fstab(5).  mountall(8) emits
       this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other activity.

EXAMPLE

       A service that wishes to be running once filesystems are mounted might use:

	      start on filesystem
