<div dir="ltr">Hello, I'm trying to create a lvgroup of a few hundred pvolumes witch are virtual disks (files of +- 1Mb ) over loopdevices. what I did is the following: dd if=/dev/urandom of=/disk0 bs=1024 count=1000 #create a file with random data losetup -f disk0 #link a loopdevice to the file after this I'm able to for instance mkfs.ext3 /dev/loop0 and mount it but I don't want a ext3 I want LVM partition. But fdisk is unable to create it using fdisk /dev/loop0 fails... So what I did first create a LVM partition of 1MB on a memorystick and then change the if of dd to point to the LVM partition, I'm now able to pvcreate /dev/loop0, vgcreate SmallDisk /dev/loop0. But I'm unable to create a logical volume in the SmallDisk group... what am I doing wrong here? is it even possible if not why? Thanks, Greetings Geert ps. for people interested, I'm trying to create a disk of allot of small virtual disks so I can create a encrypted partition on for instance gmailfs and minimalize up/download time on changes. Pretty cool if it's possible no? </div>
