Imaging using partclone instead of partimage

[Gilou]

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]

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.

patch -p1 tmp/bin/fog < ./fog.diff.txt

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

[Hongyun]

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!

[Tom Elliott]

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.

[Hongyun]

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.

[Gilou]

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

[Tom Elliott]

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,
