Subject: Odp: [linux-lvm] Using pvcreate with file...
Date: Mon, 31 Jul 2006 20:41:08 +0200	[thread overview]
Message-ID: <s4ce6af4.001@pia01.lukas> (raw)

connect "vm1disk" file to "/dev/loop0" device:
# losetup /dev/loop0 vm1disk
display info about /dev/loop0:
# losetup /dev/loop0
use it to create pv:
# pvcreate /dev/loop0

later delete the /dev/loop0 <-> vm1disk binding by issuing command:
# losetup -d /dev/loop0
(do it after "pvremove /dev/loop0")

cheers,
bartek

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.
