Win7x64 : Golden Image : partitions problems ... again

Sebastian Roth

I’m guessing the encoding gets messed up somewhere along the road

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

@Jonathan-Cool said:

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

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.

Quazz

@Sebastian-Roth Yes, the first and third e should be é but, the second e should just be a plain e!

Observe

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

The word it should look for is Réservé

It will never match under these conditions and explains why the problem remains unsolved, imo.

Jonathan Cool

Hi !

You right @Quazz … the good word is “Réservé” and not “Résérvé”.

I’m back with the results of commands (on VM Golden Img) :

my fog.postint :

I think, this fix is not good : https://github.com/FOGProject/fos/blob/master/Buildroot/board/FOG/FOS/rootfs_overlay/usr/share/fog/lib/funcs.sh#L493

Maybe the good fix is : line 493 :

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

Quazz

@Jonathan-Cool I created a pull request for this, but in the mean time you can of course edit those files on your own install already. Should do the trick, I reckon.

edit: Although, looking back, part of the problem is how blkid spits out the label when using é

blkid | grep /dev/sda1

Should spit it out.

I’ve tested a bit myself and the same thing happens on my French installs.

Will need further looking into.

I also noticed I can’t type in certain characters in FOS such as é, perhaps related, will look into it later.

Sebastian Roth

@Jonathan-Cool Arghhhh, I got it wrong again. My bad!

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

Keeping my fingers crossed I get it right this time…

@Quazz Thanks for finding the tripple é’s. Didn’t notice that. My guess is that it won’t help much because the label printed is not in the same character encoding as you noticed already. Thanks for the pull request. Shall I merge? I still hope we can come up with a way to pinpoint those partitions without labels. See my detailed comment here: https://github.com/FOGProject/fogproject/issues/195 (looking for files on the partitions might be way more reliable I hope)

Jonathan Cool

Hi,

Thank you both for you precious help …

Back with the results : https://drive.google.com/file/d/1hJXQ-H7C4gZPvAUlPlVz9CzmFmBeVLK2/view?usp=sharing

@Quazz : How i can fix my funcs.sh ? i can hack it with my fog.postinit i think ? With sed tool …

Sebastian Roth

@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).

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.

Hm, it’s seem not match …

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

@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

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?
