@george1421 Yes You are absolutly right but this would still be slow :

Let’s say the machine will have sda as fog target disk.

20 times I will have to :

1- Delete the Host
2- Quick register
3- Host reboots ( close to 3 minutes here ) - Change the disk on sda
4- Flash Time over network.

on the other side, I I had my ownclient , I could just plug on eSata ( or USB) , click flash , next etc…

@george1421 Can you maybe point me to the source code on teh client side that handles the restoring of the image ?

I could then rewrite a GUI that does the same as Fog. thanks

Maybe over here ? https://github.com/FOGProject/fog-imager/blob/master/scripts/fog.deploy ?

@george1421 HI

Yes we could use some clonezilla , but Fog has a major advantage : it automatically resize the Root partition allowing use to restore on any disk size.

I know this would be pretty simple to script, I though mpaybe someone has done it before.

the closest information for now is

https://wiki.fogproject.org/wiki/index.php?title=Troubleshooting_an_image_push_to_a_client

But I’d like to add info for linux .

mm Ekimia

Let me explain :

I have my Fog images Ready.

I have 20 Disks on my desk ( connected on USB3) and want to load fog linux single disk resizable ( Root + Swap) images onto those disks like I would have done booting the Fog client, but without having to boot the fog PXE client each time.

How could I do that ?

I know the Fog client basically :

restore MBR
Use partclone to restore partition
restore swap UUID

But I guess We can extract the full client and run it from my linux distro desktop directly ?

Something like Fogclient --image /images/image1 --target /dev/sdb

Thanks !

Thanks, But do you think those kernels would handle de USB ethernet dongle ? From what I have tested , it seems it does not ?

Hi,

I’ve read a lot of threads about USB booting into the fog menu but I’m a bit lost, sorry if this sound like “RTFM”

Currently I have one machine with USB ethernet which can boot Legacy and EFI USB key.

What I do currently :

Boot an USB linux distro
Create the partition
Mount the NFS images directory
Partclone restore the partition img
update the swaplabel with the original UUID
grub-install using the new root partition.

As you see I’m doing pretty much the same what Fog is doing.

What are my option here ?

If I boot Gpxe and pxe style iso from USB , It does not see the USB ethernet adaptater
COuld I boot a full OS that would chainload the Fog menu and then carry on as usual ?
Or even better , could I boot the Fog menu completly from USB ?

Thanks

Hi I forgot to end this thread.

We solve this problem by going full Legacy bios on all machines. restoring a singledisk multipartition works great (root partition resizing included)

Thanks everybody for this great project.

[quote=“Junkhacker, post: 39232, member: 21583”]most machines are UEFI now, but everyone i know (who knows what they’re doing, anyway) runs them in legacy mode.[/quote]

Well, We actually know what we are doing as well

The point is that we don’t use Fog to handle a classroom or a bunch of company computers but we use it for Linux preinstalled laptops Business.

This lead us to want to keep using EFI for now but you’re right maybe we’ll finally hit a wall and go back to legacy bu that I’m afraid that legacy mode won’t be supported forever in a few years on new machines .

I didn’t dig the master branch of FOG yet but I guess this might be something like :

I found a partition of type EFI : don’t resize
I found a swap partition : don’t resize ( and reuse the UUID as it’s already done now in legacy mode )
I found a root partition : resize it to the maximum the disk can handle ( as it’s already done now in legacy mode )

So the gap does not seems to hard but I’m not expert in this area.

Will be happy to sumbit a patch if my skills allow it.

mm Ekimia

thanks !

I meant standard as most of the machines are UEFI now. but you are right I don’t now if it’s really feasible to restore and grow with this layout.

mm Ekimia

Nobody ?

this is a pretty standard need, isn’t it ?

Cloning an UEFI linux system with a Root partition and a swap partition, how others do then ?

Hi , first post , thanks a lot for your work on Fog, it’s an amazing tool.

So far we only succeed to use FOG 1.2.0 for our Linux preinstalled laptops ( [SIZE=11px][FONT=Ubuntu][COLOR=#555555]Single Disk - Resizable) [/COLOR][/FONT][/SIZE] :

Legacy boot machines with sda1= Swap and sda2 = / , it sucessfully resize sda2 on any disk size which is great!

But we still fail on UEFi machines ( [SIZE=11px][FONT=Ubuntu][COLOR=#555555]Single Disk - Resizable) [/COLOR][/FONT][/SIZE] :

Sda1 = EFi partition ( FAT)
sda2 = Root
sda3 = Swap ( fixed size we’d like)

Fog restore the initial Partition table, but creates only sda1 and sda2, sda3 is not created at all it seems.

So right now, we still have to boot on a live USB , resize sda2 if needed , create the Swap , and update fstab with the correct swap uuid.

Do you think we need maybe to move the swap on sda2 ? or Fog might be unable right now to do this kind of layout ? then what kind of patch would be needed to achieve this ?
