Imaging using partclone instead of partimage
-
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,

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!

If you’re using the 0.32 init.gz file, it doesn’t come precompiled with the partclone files.
Have you built your own init.gz file with partclone? If so, then I can do the script, if not, there’s not a lot that I can do to help.
I could build you a custom init.gz but I don’t know how much you would enjoy that as I don’t have the capacity (at the moment) to test this. I’d basically be building in the dark.
-
Thanks for trying to help me. I can try the 0.33b version again. But do you know why when I patch 0.33b there is one error, is it critical? Please see my above post.
-
Also, I will try to give more insight on how to be able to resize ext[34] partition… There are no reason not to do the same we do for NTFS partition using resize2fs, assuming it’s inside the init.gz, haven’t even checked for it yet
-
Gilou,
It does not currently contain resize2fs. I’m building another version of init.gz right now with resize2fs enabled. Hopefully this will help you, and all of us out.
Thank you,
