Win7x64 : Golden Image : partitions problems ... again

Jonathan Cool

Hi !

First, you can see my configuration into my signature

Since one year, i use universal image to deploy Windows 7 x64 on many differents models (o3020, o3040, o7010, HP820G3 …) but i have a problem partition …

After a deploy, the Reserved System partition (in french «Réservé au système ») don’t have a right size … :

on Optiplex7010 : 305Gb for the « Réservé au système » partition. 159Gb for the C drive
on Optiplex7050 : 78Gb for the « Réservé au système » partition. 159Gb for the C drive
on Optiplex5050 : 771Gb for the « Réservé au système » partition. 159Gb for the C drive

This issue can be circumnavigated by editing the d1.fixed_size_partitions file but it’s not a real good solution because it’s need an human intervention after every update of the universal image … so, i think, the solution recommanded by @george1421 seem the good way … but, i not sure if i really understood the answer …

I need to edit the postinit file but, what i exactly do with this file ? Searching for the « Réservé au système » partition to set it to 100Mb ?
I’m confused about that …

VirtualBox configuration :
Version : 5.0.26
VM configuration disk :
Virtual Size : 160Go
Real Size : 9,12Go

Windows disk Manager on VM :

Windows disk Manager on HP8000 after deploy :
https://drive.google.com/open?id=0B48PuYLEHxQLdzRHb0EtY1k2NkU

We can see the big size of the reserved parition … not 100Mb but 72Go !

Windows disk Manager on DELL o7010 after deploy :
https://drive.google.com/open?id=0B48PuYLEHxQLSUdpam1STEV0cjg

On the optiplex 7010, same problem … the reserved partition is more larger … 305Go.

On the both computers, the system C partition is always 159Go ….

I juste want this simple partitionning :

"Réservé au système" : always 100Mb
System C partition : rest of the disk ……

I don’t use sysprep to expand or touch any partition.

What can i do to use all space for the C partition and have a classic 100Mb reserved partition ?

Have you looked into this yet? George’s thread about this is pretty straight forward - that is, if you know a bit of shell scripting.

If not you can still choose the other way and follow my advise here: https://forums.fogproject.org/post/96948

Jonathan Cool

Thank you for the answer !

I have already saw theses topics

But … i’m on FOG 1.4.2 … i searched if newer version fix the label partition problem and i can’t found any annoncement to say that … Maybe i can update my FOG Server to the lastest … but i just want to be sure this issue has fixed …

Sebastian Roth

@Jonathan-Cool I am not saying you need to update. Those threads explain how to modify the scripts (either manual or on the fly when booting).

I just looked at the code again and seems like Tom actually added the French label: https://github.com/FOGProject/fos/blob/master/Buildroot/board/FOG/FOS/rootfs_overlay/usr/share/fog/lib/funcs.sh#L493

So I would think if you update to 1.5.4 you should have this fixed.

Jonathan Cool

Thank you

I wil try to update my fog server to 1.5.4

I will be back for the feedbacks

Jonathan Cool

Hi !
I’m back after the 1.5.4.8 update … and the issue is still there

I tried to deploy my Golden Image on the 3 optiplex and i had the same results … very large reserved partition.

I opened the fog.upload on a debug client task (ssh session) and checked the funcs.sh file :

            local label=$(getPartitionLabel "$part")
            if [[ $label =~ [Rr][Ee][Cc][Oo][Vv][Ee][Rr][Yy] ]]; then
                echo "$(cat "$imagePath/d1.fixed_size_partitions" | tr -d \\0):${part_number}" > "$imagePath/d1.fixed_size_partitions"
                echo " * Not shrinking ($part) recovery partition"
                debugPause
                return
            fi
            if [[ $label =~ [Rr][Ee][Ss][Ee][Rr][Vv][Ee][Dd] || $label =~ [Rr][�~Ié][Ss][�~Ié][Rr][Vv][�~Ié] ]]; then
                echo "$(cat "$imagePath/d1.fixed_size_partitions" | tr -d \\0):${part_number}" > "$imagePath/d1.fixed_size_partitions"
                echo " * Not shrinking ($part) reserved partitions"
                debugPause
                return
            fi

I take a picture of the same file directly on screen … : https://drive.google.com/open?id=12wiSow0jfowtj85T0AI9NF_CvkH9eMyW

What can i do to find the culprit ? Maybe it’s not a FOG problem but a problem during the Golden Image creation with Virtualbox ?

Sebastian Roth

@Jonathan-Cool Too bad to hear this has not worked for you! I remember having that weird feeling when this was added that those accents might cause an issue. Can you please do another debug session an run the following command: blkid -po udev $part | grep FS_LABEL

Let’s see how the label looks like on your machine.

Jonathan Cool

Hi !
I ran a new debug task on a client …

[Wed Sep 12 root@fogclient ~]# blkid -po udev $part | grep FS_LABEL
blkid: The low-level probing mode requires a device

[Wed Sep 12 root@fogclient ~]# blkid                               
/dev/ram0: UUID="885cb2cc-e11f-4e88-8182-ee60a35f43d1" TYPE="ext2"
/dev/sda1: LABEL="RM-CM-)servM-CM-) au systM-CM-(me" UUID="8E4C92C44C92A70D" TYPE="ntfs" PARTUUID="c91a5cff-01"
/dev/sda2: LABEL="System" UUID="46E2941BE29410F3" TYPE="ntfs" PARTUUID="c91a5cff-02"

On the 2nd command, we can see the very strange label of /dev/sda1 … !

Edit : I deployed a classic image on o7010 and tried the same commands : same results … :

[Wed Sep 12 root@fogclient ~]# blkid
/dev/ram0: UUID="885cb2cc-e11f-4e88-8182-ee60a35f43d1" TYPE="ext2"
/dev/sda1: LABEL="RM-CM-)servM-CM-) au systM-CM-(me" UUID="A27C916A7C9139CD" TYPE="ntfs" PARTUUID="3f61e1ac-01"
/dev/sda2: LABEL="System" UUID="34C09543C0950BEC" TYPE="ntfs" PARTUUID="3f61e1ac-02"
[Wed Sep 12 root@fogclient ~]# blkid -po udev $part | grep FS_LABEL

@Jonathan-Cool Ok, should have listened to my intuition - those character encoding things are just a nightmare.

I think it’s wise to step back and try the route mentioned earlier. Edit /images/dev/postinitscripts/fog.postinit on your FOG server and add a single line to the end of that script so it would look like this:

#!/bin/bash
## This file serves as a starting point to call your custom pre-imaging/post init loading scripts.
## <SCRIPTNAME> should be changed to the script you're planning to use.
## Syntax of post init scripts are
#. ${postinitpath}<SCRIPTNAME>

sed -i -e "s#\\[Rr\\]\\[Ee\\]\\[Ss\\]\\[Ee\\]\\[Rr\\]\\[Vv\\]\\[Ee\\]\\[Dd\\]#RM-CM-\\\)servM-CM-\\\)#gi" /usr/share/fog/lib/funcs.sh

You know, regular expressions are just a bit tricky and those triple backslashes really look confusing. But I kind of tested this and I am fairly sure this should work if you get it all right.

Save the file and boot up your client with a debug upload task. When you get to the shell run fog and right after it said “Running post init scripts” you want to stop it for the moment (ctrl+c). Then check to see if the script did its work: grep label /usr/share/fog/lib/funcs.sh and you should see something like this:

            local label=$(getPartitionLabel "$part")
            if [[ $label =~ [Rr][Ee][Cc][Oo][Vv][Ee][Rr][Yy] ]]; then
            if [[ $label =~ RM-CM-\)servM-CM-\) || $label =~ [Rr][Éé][Ss][Éé][Rr][Vv][Éé] ]]; then
# Gets the volume group name/label.
# Get's volume labels from volume group.

If your third line looks like this I would give it a try, just start the task again using the fog command. If it does not, play with the postinitscript and try again.

i understand your way and your test … but if i really understood, i do the debug upload task on my VM ? Because you said “upload task” …

Yes, exactly what I meant!

Ohh dang, I forgot the patch for fog.upload. So please edit your /images/dev/postinitscripts/fog.postinit again and make it look like this:

#!/bin/bash
## This file serves as a starting point to call your custom pre-imaging/post init loading scripts.
## <SCRIPTNAME> should be changed to the script you're planning to use.
## Syntax of post init scripts are
#. ${postinitpath}<SCRIPTNAME>

sed -i -e "s#\\[Rr\\]\\[Ee\\]\\[Ss\\]\\[Ee\\]\\[Rr\\]\\[Vv\\]\\[Ee\\]\\[Dd\\]#RM-CM-\\\)servM-CM-\\\)#gi" /bin/fog.upload
sed -i -e "s#\\[Rr\\]\\[Ee\\]\\[Ss\\]\\[Ee\\]\\[Rr\\]\\[Vv\\]\\[Ee\\]\\[Dd\\]#RM-CM-\\\)servM-CM-\\\)#gi" /usr/share/fog/lib/funcs.sh

Hopefully I got it all right this time and it will upload the image for you in a way that you don’t have to change p1.fixed_size_partitions manually anymore.

Jonathan Cool

Hi,

I’m back after few off days …

I tried your patch on the VM, upload the new image and tried a new download … it’s didn’t work.

I tried to play with backslashes and no more sucess …

BUT, i have an other idea :

run the VM
go to the Disks Management tool
right click on the “Partition réservé au système”
rename this damn partition to “System Reserved” (<-- it is the right US/english name ?)
upload the image on FOG
try a new DL on client …

What do you think about that idea ?

Quazz

@Jonathan-Cool That should straight up work, but ofc doesn’t really help us prevent this problem in the future for new people.

Jonathan Cool

You totally right …
I will try the download with the modified name partition.
If it’s works, we can realize new tests with the “sed” command hack to permanently fix this issue for all french people.

Quazz

@Sebastian-Roth Just wondering, but would it be possible to use unicode here for the accented characters?

edit: Just tested and no…

Though I wonder, can we just use the characters directly? My small test seems to think so. Which means:

if [[ $label =~ [Rr][Ee][Ss][Ee][Rr][Vv][Ee][Dd] || $label =~ [Rr][�~Ié][Ss][�~Ié][Rr][Vv][�~Ié] ]]; then

Can be rewritten and simplified to:

if [[ $label =~ [Rr][EeÉé][Ss][EeÉé][Rr][Vv][EeÉé][Dd]? ]]; then

I’m guessing the encoding gets messed up somewhere along the road �~Ié likely simply means é. Don’t know how or when this happens/happened, but that’s my guess (I’ve seen this before trying to sort out data in different languages)

Jonathan Cool

Hm, we are close to find the issue … I can confirmed … when i renamed the system partition in my Golden Image, the reserved partition has the good size after a deploy on a o7010 …
So, the intuition was good … !

Exactly what is happening. I don’t fancy trying to get the encodings right because this will break sooner than later again.

Can you please do another test, same way but do a debug upload and when you get to the shell run grep label /usr/share/fog/lib/funcs.sh, take a picture of the screen and post here. Just so we get an idea if the patching really works.

Jonathan Cool

Hi !

@Sebastian-Roth I ran an upload debug task on VM and did the command : https://drive.google.com/file/d/1s1CVoUuPlNNCEK7bcn6TBpclbK4hc2bK/view?usp=sharing

What do you think about the result ?

Quazz

I wanna smack myself in the head.

I think the problem is simply that the second e is accented in the test whereas it shouldn’t be.

Why do you think it shouldn’t be?? Reading what Jonathan posted a while ago I see two encoded e’s…

@Jonathan-Cool Looks good but… hmm?? Sorry for the forth and back here but can you please do another debug capture and run the following three commands:

grep label /usr/share/fog/lib/funcs.sh
grep label /bin/fog.upload
blkid -po udev | grep sda1

Again take a picture and post here. Just so we have it all on one screen.
