Imaging using partclone instead of partimage
-
The only thought that sticks out to me is the idea that it’s looking for the file d1p1.img.000 and I believe the system only makes the files d1p1.img
Just a thought, though I don’t think that’s fully the fix yet.
I’ll take a look into the bowels of the fog script for when it moves the file.
-
Found the issue.
So I’m correct.
The script makes the files d1p1.img
Then when it tries to move the files it runs:
mv ${imgpart}.000 ${imgpart}
I Imagine this is backwards as the .000 file doesn’t exist at all during this.
If you’re unafraid to play a little in the bowels, you can fix this.
Perform the steps in this as before.
Use your editor for editing the file
Look for the lines that say mv ${imgpart}.000 ${imgpart} and switch it so it reads: mv ${imgpart} ${imgpart}.000
That should help you out.
-
What about this line: mv ${imgpart}.000 ${imgpart} 2>/dev/null
change it as well? -

-
Now I get the same error without 000
mv: Can’t rename ‘/images/7071bc7b70bd/d1p1.img.000’: No such file or directory
But I found the mac address folder under /images/dev/
-
One more question, do I need to have partclone installed on FOG server?
-
No. Partclone becomes a part of the init.gz file.
-
[INDENT=1]So you mean the [FONT=Consolas]partclone.diff.txt file already included everything I need to use partclone?[/FONT][/INDENT]

Hi Tom,
Have you ever used clonezilla? someone recommends that for me, but if I could make FOG work with ext4, I really don’t want to switch to something else.
Hongyun -
That’s kind of the point behind partclone vs. partimage. That’s really the main difference between clonezilla and fog.
-
I’m sorry that this is taking so long. I’ve got the code base, I think, setup and ready to run, but I keep getting a funny error. I can’t build partclone natively within buildroot, but I’ve successfully built the binaries on my 64 bit system. I just created a 32 bit VM to see if I could create the binaries on that and have them run properly, though I don’t know how well that will actually work.
It’s a work in progress, that’s for sure.
-
There is a bug if you use my patch, I missed a spot where partimage is still used. I need to work a bit more on that, and we need either a way to tell “use partclone or partimage” (say, an image type), or a way to effectively migrate from the partimage+gz format to partclone + gz. But that requires a better roadmap thinking than just changing a few lines… And the fog sh script is also not consistent, a lot of things should be refactored in it to allow for an easier development on it…
As for “how I did it”, well, I’m a bit familiar with partclone (I use it for MacMinis), and the documentation is rather extensive. The catch might be with pigz / gzip, as pigz doesn’t return properly when reading stdin, but gzip is available in the buildroot environment, so there it goes…
I have huge issues building buildroot, 32 bits or 64 bits, vanilla or the one descried on SVN, or as a matter of fact, even the one listed on your website (Tom)… And I won’t have immediate time to work on that, but I’ll look into it… My goal is to work on a 64 bits buildroot + kernel, to be able to exploit the 16 GB RAM monsters properly…
-
I’m almost prepared for releasing a working model of my init.gz (non 64bit) that is now operating with creating the image. I’m just doing some testing to see if I can get the progress information to display. However, it works across the board, extfs or ntfs, and theoretically multicast.
-
Thank you, Gilou and Tom! I wish I knew more about programming, and really hope I can do something to help, but it looks like my only hope will be waiting for you guys to come up with a working solution.

Attached, find my patch for the fog script to use partclone instead of partimage.
Hopefully it helps.
Copy it to your fog server, preferably in /tftpboot/fog/images
Then:
Run these commands to edit your init.gz file. (MAKE SURE YOU’RE ON AS ROOT YOU NEED TO MOUNT THE IMAGE)
[code]cd /tftpboot/fog/images
mkdir tmp
gunzip init.gz
mount -o loop init tmp
patch -p1 tmp/bin/fog < fog.diff.txt
umount tmp
rm -rf tmp
gzip -9 init[/code][url=“/_imported_xf_attachments/0/445_fog.diff.txt?:”]fog.diff.txt[/url]

Hi Tom,
Can I use this script under version 0.32? Honestly, I like 0.32 better than 0.33b
Thanks,
Hongyun -
Here is the result when I applied the patch to 0.32, and attached is the fog.rej file.

I’ll take a look at the fog 0.32 fog script and make the changes to it. The diff I gave you before is for 0.33

When I applied it to 0.33b here is the result:

If you could make it work on 0.32, it would be so wonderful! Thank you very much!
