[linux-lvm] Using pvcreate with file...

[Arsen Hayrapetyan <ahairape@mail.cern.ch>]

Hello,

I am newbe to the lvm and I have the following issue:
My system is partitioned in the following way:

===============================================================
   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          16      128488+  83  Linux
/dev/hda2              17        4767    38162407+  83  Linux
/dev/hda3            4768        4865      787185   82  Linux swap
===============================================================
There is no free space left on the disk.

I created the separate files, which I want to be lvm-enabled; I 
used the following commands:

==============================================================
#> cd /
#> dd if=/dev/zero  of=vm1disk bs=1k seek=16384k count=1
#> mkfs -t ext3 vm1disk

#> dd if=/dev/zero of=vm1swap bs=1024k count=1 
#> mkswap vm1swap
==============================================================

Now I want to initialize that "disk" for lvm-use.
So what I need to do?

pvcrete ..........................?

I had a look at the documentation, but they deal with real partitions
and disks (as far as I understood), not with files...

Thanks in advance to everyone who responds,
Arsen.
