fog.drivers script will not run correctly in postdownloadscripts

george1421

Wait, I just found a flaw in the script from Lee’s page (note: not a script Lee created though) for Windows 10, for Win7 its correct since the last partition on disk 0 is the windows partition.

        getPartitions $hd
        for part in $parts; do
            true
        done
        dots "Mounting partition $part"

This loosely gives me the last partition for Win10. But that is NOT the windows partition. In the case of the system I’m testing there are 3 partitions, but partition 2 is the windows partition. I’m not using rsync but just regular copy that threw the error.

I think more intelligence needs to be built into this loop, where it should check to see if the /windows directory exists before exiting.

Quazz

@george1421 I personally use

echo -n " * Mounting Windows File System...................";
if [ -b /dev/sda4 ]
 then
    mount.ntfs-3g /dev/sda4 /ntfs 2>/tmp/mntfail
 else
    mount.ntfs-3g /dev/sda2 /ntfs 2>/tmp/mntfail
fi

Logic: If the system has 4 partitions (or more), then (assuming singleboot windows) it is a GTP installation and Windows is on partition 4. Otherwise it’s a MBR installation and it will generally be on partition 2.

This is incredibly over simplistic, however and only reliably works on clean microsoft images, not OEM or the like.

A loop function would need to be created to check for the windows folder or something.

george1421

@Quazz I had a similar simple conditional test, until I ran into a NVMe drive with its crazy disk naming of /dev/nvme0n1[partition]

Quazz

@george1421 Good point, we mostly deal in refurbished hardware and my script is non critical, so it hasn’t been a big deal for me so far.

george1421

@Quazz Unless the @Senior-Developers can come up with a brilliant way to find the windows partition, I think we are going to have to mount each partition, in order, until we find one that has the /Windows directory on it. That is kind of an expensive way to do that (in CPU time).

Quazz

@george1421 We can already reduce that by selecting only the NTFS partitions to try though.

PARTITIONS=$(df -T | grep ntfs | awk '{print $1}')

edit: I just realized this may not work on unmounted partitions, I’ll correct in a bit.

Tom Elliott

@george1421 There’s already a way.

It sounds like the partitions aren’t being processed based on:

@THEMCV said in fog.drivers script will not run correctly in postdownloadscripts:

@Quazz I did not, no. I think I found the /fog reference though and might be our problem.

I think it might be my postdownload script itself.

#!/bin/sh

    clearScreen;
    mkdir /ntfs &>/dev/null
    ntfs-3g -o force,rw $part /ntfs #mount image (remember this is mounting partition [U][B]after[/B][/U] new image is deployed)
    mkdir /fog &>/dev/null
    mount -o nolock,proto=tcp $storageip:/fog/ /fog #this is a share created on server under /fog which contains drivers, software etc.. (just add /fog to exports but you could use existing location i.e. /images and if you do, do not ne$
    dots "Mounting Device";
    if [ "$?" = "0" ]; then
        echo "Done";
        . ${postdownpath}fog.drivers # run fog.drivers script
        umount /ntfs; # unmount when all is done :-)
    else
        echo "Failed To Mount Device";
        sleep 30;
    fi
fi

@Wayne-Workman I removed it and am testing it now.

The ntfs-3g -o force,rw $part /ntfs is using the last partition FOG processed instead of looping the partitions separately.

If it were me (psuedo code here) I’d end up doing something like:

        getPartitions $hd
        for part in $parts; do
            umount /ntfs >/dev/null
            fsTypeSetting "$part"
            case $fstype in
                ntfs)
                    dots "Mounting partition $part"
                    ntfs-3g -o force,rw $part /ntfs
                    if [[_! $? -eq 0_]]; then
                        echo "Failed...Trying next partition"
                        continue
                    fi
                    if [[_! -d /ntfs/windows && ! -d /ntfs/Windows && ! -d /ntfs/WINDOWS_]]; then
                        echo "Done...no valid Windows directory found"
                        umount /ntfs
                        continue
                    fi
                    echo "Done"
                    break
                    ;;
                *)
                    echo " * Partition $part not NTFS filesystem"
                    ;;
            esac
        done

Of course this isn’t tested, and just thoughts through my head. Replace the _ with spaces.

george1421

Tom was able to do a bit of magic below. I tested it in my dev environment and it works to correctly find the windows partition. It needs a bit of cleanup work (hiding some unnecessary messages) but all in all it w is a brilliant bit of code.

THEMCV

@george1421 said in fog.drivers script will not run correctly in postdownloadscripts:

@THEMCV OK what I think I would do at this point is insert a debug pause after the error generator.
#/fog/Drivers/Win7/Latitude E5410/x86
rsync -aqz "$remotedriverpath" "$clientdriverpath" >/dev/null 2>&1
[[! $? -eq 0]] && handleError "Failed to download driver information"

debugPause
After the handleError line after the rsync.

Then go back and schedule a deployment to this computer but pick the debug deployment checkbox.

Then pxe boot the target computer. It will print out a bunch of text but drop you to a command prompt. From there key in fog This will single step you through the deployment process. When you get to the point of the error press crtl-C to exit the installer script. This will leave you at a linux command prompt. From there we should be able to check the disk size and what not.

Okay, done. running the command df I get:

Filesystem                   1K-blocks                Used        Available      Use%      Mounted on

I will run @Tom-Elliot’s code and report back.

THEMCV

@Tom-Elliott So this goes into fog.postdownload alone or conjoined with the previous script from ntfs-3g -o force,rw $part /ntfs down?

@THEMCV please stand by. I think I have a working solution based on tom’s script. I just want to make sure it doesn’t break anything else. I realize we are sending you in 10 different directions, because each has their own way to go about this.

We really need to get a wiki page built with a step by step.

THEMCV

@george1421 No problem.

That would be nice though. I had to jump through a few threads (which is a given sometimes!) and the wiki page for Auto Installing drivers didn’t seem as robust as the scripts that I had found.

But that’s how progress and the process work. One problem at a time and always improving.

george1421

@THEMCV First understand this this script won’t copy and paste correctly. For some reason the FOG Forum pages eat the spaces around the conditional tests, but I wanted to get it out here for viewing. I’ll upload the file in a minute.

Tom: the only question I have is if NO partitions match will the test if [[ ! $? -eq 0 ]]; then still trap it?

@george1421 The -eq 0 directly after the done part of the loop will be enacting on the last command ran.

In this case it would either be echo or break which both will always equal 0.

The if I’m referring to is not needed because you’re looping directories and immediately after the main mount you’re testing already.

To correct this, and leave this there, you can add a variable in the first check of the mount success by doing something like:

ntfsstatus="$?"
if [[_! $ntfsstatus -eq 0_]]; then
    echo "Skipped"
    continue
fi

Then change the if check after the loop to check for $ntfsstatus instead of $?.

A lot of refinement can be added admittedly.

THEMCV

@george1421 @Tom-Elliott @Quazz Okay, it looks like it worked! Amazing!

You guys are simply the best devs/mods/team ever.

Although I forgot to disable FOG Client in my sysprepped image, I fixed and and will be double testing again. It went through the section without a hitch though.

Tom Elliott

@THEMCV safe to solve the?

george1421

@THEMCV That’s great. I’m going to compile the results of this thread into a tutorial page tonight to get everything in one spot again.

THEMCV

@Tom-Elliott Yep, it’s working extremely well. Thank you for helping me (and writing a piece of code for me!).

@george1421 Sounds great, that’d be amazing! All of the past places that I’ve worked at (I’m in contact with them after I left) will appreciate the write up. They’ve been wanting to get master images rolling at their school districts (one being ~1,000 PCs), but never have gotten to get them up and running.

george1421

@THEMCV I did create a write up for creating a single golden image for multiple platforms here: https://forums.fogproject.org/topic/7391/deploying-a-single-golden-image-to-different-hardware-with-fog But because of my NDA with my company I can’t include any of my own scripts. Now with what Tom, Lee an other produced I can compile that into a single document.

But this next one will be short and to the point copy and paste this and it “should” work as designed. I’ll leave the big words on the other documents.

THEMCV

@george1421 Ah yes, I did read over that one a bit! I finally got it figured out, but I didn’t end up using MDT. Very thorough.
