Re: [coLinux-users] How to access a logical partition

Hello Henry,

The only thing you need to do to reproduce the behavior is to
set the partition type to 8e ("Linux LVM / Solaris") with fdisk.

If you want to make further experiments with LVM, you should boot
a diskless Linux (e.g. Knoppix) and  set the partition type to 8e.

Then:
create a LVM physical volume on the partition:
  pvcreate /dev/hda8

create a volume group:
  vgcreate test /dev/hda8

create a logical volume within the volume group
  lvcreate -n vol1 -L 1G test

The volume group's device is now visible under /dev/test/vol1 , which
is a symbolic link to /dev/mapper/test-vol1 . You can handle it like
an ordinary partition, e.g.

mkfs.ext3 /dev/test/vol1
mount -t ext3 /dev/test/vol1 /mnt/volume1

Use the commands pvs, vgs, and lvs to list the physical volumes,
volume groups, and logical volumes on your system.

Use pvscan, vgscan, and lvscan to rescan the LVM configuration
after attaching a device or making externally changes.

Thank you for your support!

Harald
