Win7x64 : Golden Image : partitions problems ... again

Quazz

@Sebastian-Roth Yes, your pull request seems much better, although I do wonder if there won’t be any problems with a file based approach, what if someone creates a similar structure on their other partitions for some reason?

Btw, the whole label thing is very strange with the encoding because even when you search for the exact label as blkid prints it out, it still doesn’t match.

The ID_FS_LABEL as Jonathan has already provided seems to have the correct encoding, though.

Very strange indeed, but for the time being this could be what we are looking for.

Quazz

@Sebastian-Roth Perhaps we could use something like

parted -l /dev/sda | grep boot | awk '{print $1}'

(making use of the partition flags to find the correct partition, since flags should always be in English in FOS, this should work across the board)

Which will return the partition number for the boot partition (for both linux and windows even)

All these tools are already present in the inits.

Can also use similar commands to find other special cases

Microsoft reserved partition (Windows 10 UEFI installations, typically third partition)

parted -l /dev/sda | grep msftres | awk '{print $1}'

Hidden “Basic data partition” (Windows 10 UEFI installations, typically first partition)

parted -l /dev/sda | grep hidden | awk '{print $1}'

Linux swap

parted -l /dev/sda | grep swap | awk '{print $1}'

Linux LVM

parted -l /dev/sda | grep lvm | awk '{print $1}'

The only edge cases coming to mind are Windows XP and such maybe. They might set the boot flag on the only partition.

But it shouldn’t be hard to detect if there’s only one partition in which case skip the remaining logic because it would be pointless to check.

@Jonathan-Cool Holy crap (sorry)! Thanks heaps for testing both blkidcommands, the one Quazz posted and the one I did. I would have never expected those to return such different results!! As we use the blkid -po udev syntax in the scripts (ref) we are back in the race. Mind trying this script:
#!/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#\[Rr\]\[Ee\]\[Ss\]\[Ee\]\[Rr\]\[Vv\]\[Ee\]\[Dd\]#\[Rr\]\[Éé\]\[Ss\]\[Ee\]\[Rr\]\[Vv\]\[Éé\]#gi" /bin/fog.upload
sed -i -e "s#\[Rr\]\[Ee\]\[Ss\]\[Ee\]\[Rr\]\[Vv\]\[Ee\]\[Dd\]#\[Rr\]\[Éé\]\[Ss\]\[Ee\]\[Rr\]\[Vv\]\[Éé\]#gi" /usr/share/fog/lib/funcs.sh
Again, boot up the client in debug mode and run:
grep Vv /usr/share/fog/lib/funcs.sh
grep Vv /bin/fog.upload
blkid -po udev /dev/sda1 | grep LABEL
If those match you can go ahead and capture the image (issue command fog on the console and step through).

Hm, it’s seem not match …

my fog.postinit :

#!/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]#[Rr][Éé][Ss][Ee][Rr][Vv][Éé]#gi" /bin/fog.upload
sed -i -e "s#[Rr][Ee][Ss][Ee][Rr][Vv][Ee][Dd]#[Rr][Éé][Ss][Ee][Rr][Vv][Éé]#gi" /usr/share/fog/lib/funcs.sh

Holy shit, i forgot to run “fog” and ctrl+c … i will be back soon with the real results …

Jonathan Cool

Back with the results … : https://drive.google.com/file/d/1Kf9DscMwdhU7VCRf5Y-L7rL86qXQc1wP/view?usp=sharing

@Jonathan-Cool Looks like the sed didn’t quite work as intended.

Try this:

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

edit: hold up, I see what’s going on here. The forum is removing the backslashes that are supposed to escape the brackets

edit2: there we go, this one should work, I think

Jonathan Cool

I’m back with bad news …

my fog.postinit :

#!/bin/bash
## ....
#. ${postinitpath}<SCRIPTNAME>

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

Upload Debug Task : Seem to be good this time … https://drive.google.com/file/d/1cv2Lerb5MGFQlwkvHO1jKcfoa8580KWv/view?usp=sharing

After a deploy on o7050, same problem : Reserved Partition : 78Gb …

Maybe i can try a debug download task to see what the hell is going on ?

george1421

@Jonathan-Cool I would do a debug deploy. Then at the command prompt ensure that both fog.upload and funcs.sh have been properly patched.

Quazz

@Jonathan-Cool Ok, so the label should match now at the very least.

Did you recapture the image since implementing the latest sed?

If so, what do your d1 files look like for this image?

Jonathan Cool

Hi,
I’m back … i typed the same commands on client during a DL Debug Task … : same results : (with SSH)

[Fri Sep 28 root@fogclient ~]# fog
 * Running post init scripts.........................Done
 * Press [Enter] key to continue
^C
[Fri Sep 28 root@fogclient ~]# grep Vv /usr/share/fog/lib/funcs.sh 
            if [[ $label =~ [Rr][Ee][Cc][Oo][Vv][Ee][Rr][Yy] ]]; then
            if [[ $label =~ [Rr][Éé][Ss][Ee][Rr][Vv][Éé] || $label =~ [Rr][Éé][Ss][Éé][Rr][Vv][Éé] ]]; then
[Fri Sep 28 root@fogclient ~]# grep Vv /bin/fog.upload 
                            *[Rr][Ee][Cc][Oo][Vv][Ee][Rr][Yy]*|*[Rr][Éé][Ss][Ee][Rr][Vv][Éé]*)
[Fri Sep 28 root@fogclient ~]# blkid -po udev /dev/sda1 | grep LABEL
ID_FS_LABEL=Réservé_au_système
ID_FS_LABEL_ENC=Réservé\x20au\x20système
[Fri Sep 28 root@fogclient ~]#

The patch seem to be applied as you can see … " if [[ $label =~ [Rr][Éé][Ss][Ee][Rr][Vv][Éé]"

@Quazz Sorry, i’m not sure if i understood the question about this file … i take a screenshot of the folder of my Golden Img :
https://drive.google.com/file/d/1iN8YbEsgOsCSu622R9qG4JzRE9xjXo1B/view?usp=sharinga
But, yes, i recapture the image before lastest sed

Quazz

@Jonathan-Cool Can you share the contents of d1.fixed_size_partitions d1.partitions and d1.minimum.partitions

Jonathan Cool

Yes i can !

d1.fixed_size_partitions :

:2

d1.partitions :

label: dos
label-id: 0xc91a5cff
device: /dev/sda
unit: sectors

/dev/sda1 : start=        2048, size=      204800, type=7, bootable
/dev/sda2 : start=      206848, size=   335335424, type=7

d1.minimum.partitions :

label: dos
label-id: 0xc91a5cff
device: /dev/sda
unit: sectors

/dev/sda1 : start=        2048, size=       52316, type=7, bootable
/dev/sda2 : start=      206848, size=   335335424, type=7

What do you think about that ?

Quazz

@Jonathan-Cool It’s very strange. The regex should definitely match now, yet it marks the wrong partition as fixed_size for some reason.

I’ve looked over the code and can’t immediatly find anything desperately wrong or incorrect for the time being.

The strange thing, imo, is that it marks the second partition as fixed, whereas we’d expect it to mark none as fixed if it were to fail (unless I’m missing something in the code, but don’t think so)

Jonathan Cool

Maybe i choose wrong parameters when i created my VM with Virtual BOX the first time ? (details on the first topic) ?

Quazz

@Jonathan-Cool Did you switch to a fixed size as I suggested in the previous thread?

Though, I don’t see how that would cause this exact problem, to be honest.

It’s very weird that you get :2 in fixed_size_partitions as I get an empty file on my W7 French installs instead. Did you assign a label to the drive per chance?

It seems like our efforts haven’t quite made the difference I hoped yet. The regex matches in my bash tests, but doesn’t seem to match in FOS in a real world scenario. I’m rather baffled as to why that is, though.

Jonathan Cool

@Quazz said in Win7x64 : Golden Image : partitions problems ... again:
Did you assign a label to the drive per chance?

Yes, my drive is named “System” into my Golden Image … https://drive.google.com/file/d/0B48PuYLEHxQLUEU5clJOZC1Vb3c/view

Maybe this name is confusing FOG ?

Quazz

@Jonathan-Cool Ideally it shouldn’t cause any problems, but because the label system seems to be having some issues, it might be a good idea to remove it before capture at least.

That should leave you with an empty fixed_size_partitions file I think…

Still doesn’t answer why the system reserved isn’t matching, it doesn’t really make any sense to me off the top of my head.

Jonathan Cool

I will try to remove this label on the C drive and recapture the image … and try a new download on the optiplex 7050.

I will be back !

Quazz

@Jonathan-Cool My “fuck this shit” solution atm is the following if you’d like to try it

Note that this is experimental and can cause issues on systems with odd labels so use at own risk… but

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

This seems to allow the regex to match at least, of course it’s far less precise now. Still don’t know why it hates é so much, but that seems to be the issue unfortunately.

Should also work on English and Dutch systems I think.

Quazz

So after some testing, I think the main problem was the case pattern matching not being able to match for some reason in FOS. (works fine on my server, however)

I’ve updated my commit to change it to the if pattern matching instead (which I already tested actually works in FOS).

Don’t know when/if it gets merged, but that should resolve issues for French Windows installs at least.
