Using Partclone to image MBR linux client using Resize option

[chris_unit]

I have a centos 7.6 client i’m trying to take an image of

it’s a only about 78gb on a 447gb disk

when i try to use single disk resizeable i get
no resizeable partitions found

here’s some information about the disk

i’m really keen to use the resizeable option as its taking nearly an abour to take an image for 78gb of data.

Looks like it a MBR partition table

@chris_unit As we can see from the output you posted this machine was setup with LVM (default in CentOS I think). FOG is not able to capture LVM setups natively. You can only capture as RAW/dd image type and deploy to the exact same disk size (same sector count).

LVM

Is there a way that i could take an image (as lvm) and then put it back at ext4 ?

[Sebastian Roth]

@chris_unit With some solid Linux knowledge you surely can convert an LVM install to a plain one but probably re-installing is a lot faster if the system is not highly customized.
