[Clonezilla-live] Problems migrating SCSI to IDE (lvm not migrated)

[Lukas G. <luk...@co...>]

Hi there,

migrating a system with LVM with ocs-onthefly from a SCSi to an IDE
machine fails when migrating the LVM.

Scenario:

SCSI-Machine: Server, disks are detected as /dev/sd*

IDE-Machine: Client, disks are detected as /dev/hda*  
<-- and this is a problem! Normaly every distri uses libata which
causes that als IDE-HDDs are detectes as /dev/sd*. Clonzilla/Debian
also uses libata, BUT they have a patch which _disables_ liabata for a
special chipset: (this is a big problem e.g. if you migrate a scsi
machine to a kvm virtual machine with ide)

-> see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=535959

The problem while migrating is, that it fails with a message like this:
"pvcreate ... cannot find deivce /dev/sda6 ... etc"

Of course, there is NO sda6, theres a hda6.

Either this is somehow in the clonezilla script fixed, or you have to
remove the debian patch from your kernel. I think the last possibility
would be ok, because, every distri uses libata for any chipset...
Also it would maybe avoid possible other hda/sda-naming problems.

Regards
Lukas
