I have successfully created and implemented and image using XP, and tried to use Clonezilla for a CentOS4.6 machine with LVM2. It is setup as /dev/sda1 as boot and /dev/sda2 as the LVM. When I attempt to create the disk image, it only "sees" the sda1 as having data and wants to create an image of only 103Mb, which I know is not correct for an 80Gb hard drive. What would cause this?

I have tried using version 1.2.1-17. In troubleshooting, I tried a FC6 hard drive in the same machine and Clonezilla recognized the LVM partition then. Is there something different with centOS?

MikeD,
Yes, this looks normal.
So how about if you run:
/opt/drbl/sbin/ocs-lvm2-start
Then run
lvs
What's the results.
BTW, if you can post the error messages (as more as possible) when clonezilla live saving your CentOS 4.6, that's better. It's easier for us know why it failed. "screen" is a good program for you to copy and paste the output on screen. You can enter screen then run "/opt/drbl/sbin/clonezilla" to start clonezilla.

For some reason it does not "see" the logical volumes on sda2, or if it does, it's not integrating them into the image file.

Update: I reinstalled Centos4 and manually setup the patitioning without LVM, and low and behold, Clonezilla worked. There is obviously an issue with Clonezilla and at least Centos' version of LVM. So until a fix comes about, I will create a new image from scratch without LVM.

Good luck and thanks for your input! I bet (hope) it's something simple! I just ran a disk to image with a FC4 drive using an LVM Volume Group with no prob. Going to do some investigating...

MikeD,
I can _not_ produce the problem here...
Today I installed a CentOS 4 (it's 4.7 now), used all the default config when installation. The partitions created by the installer are /dev/hda1 and /dev/hda2, where hda2 includes 2 LVs, one for CentOS file system and the other one is swap.
I can use Clonezilla live to save the whole disk successfully. The created image contains:
-rw-r--r-- 1 root root 4 2008-12-14 13:40 disk

So do you have something special (e.g. encrypted partiton...) on your CentOS 4.6 ?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Not sure if I do, but it is the old 4.6 version, so that might have something to do with it... at any rate I'm just going to redo the image without LVM and go from there. Thank you so much for your help!

Please boot into clonezilla live on your CentOS machine, then enter command line:
1. sudo su -
2. lvscan
3. vgscan
4. pvscan
Then post the results of 2-4.
Could you please let us know which version (e.g. 1.2.1-17) of clonezilla live are you using ? It will be easier for us to reproduce the problem.
I have tried using version 1.2.1-17. In troubleshooting, I tried a FC6 hard drive in the same machine and Clonezilla recognized the LVM partition then. Is there something different with centOS?

MikeD,
Thanks for your report. I think I have to find a CentOS 4 machine to test it. It's easier for me to see why.
Update: I reinstalled Centos4 and manually setup the patitioning without LVM, and low and behold, Clonezilla worked. There is obviously an issue with Clonezilla and at least Centos' version of LVM. So until a fix comes about, I will create a new image from scratch without LVM.
