Re: [Clonezilla-live] Using CZ with Logocal Volumes

[Johnny S. <li...@op...>]

Morning Steven. So I rebuilt the image/clone (disk to disk), and notice 
very briefly while rebooting and exiting CZ, a brief message scrolled 
past the screen indicating something about "Duplicate Volume Group...." 
or something to that effect, it went by fast. But I guess this is likely 
normal since the VG's on the source were duplicated on the target?

I then disconnected the original source drives and booted from the 
cloned drive alone in the system. Once again it kernel panicked and 
could not find "VolGroup00"

I then rebooted the CZ disk and went to the shell, and ran the following:


pvscan:

PV /dev/sda2 VG VolGroup 00 lvm2 [297.91 GiB /  0 free]
Total:1 [297.91 GiB] / in use:1 [297.91 GiB] / in no VG: 0 [0  ]

vgscan:

Found Volume Group "VolGroup00" using metadata type lvm2

lvscan


ACTIVE    'dev'VolGroup00/LogVol00' [20.00 Gib] inherit
ACTIVE    'dev'VolGroup00/LogVol02' [233.91 Gib] inherit
ACTIVE    'dev'VolGroup00/LogVol03' [20.00 Gib] inherit
ACTIVE    'dev'VolGroup00/LogVol01' [20.00 Gib] inherit
ACTIVE    'dev'VolGroup00/LogVol04' [4.00 Gib] inherit


I also tried to boot from the new cloned drive, while the old 
drives/RAID-1 were attached and although it booted, I believe it did so 
using the VG from the original drives as I got this:

found duplicate PV Rmjk001v4osy2kov4RnSPYcpux+ulurd: using /dev/sdb2 not 
/dev/sda2
