fog.drivers script will not run correctly in postdownloadscripts

Quazz

@THEMCV The fog directory does not exist by default, it must be manually created, given correct permissions and an entry in /etc/exports needs to be made to export it as a nfs share so it can be mounted on clients.

mkdir /fog
chmod 777 /fog
chown fog:fog /fog
nano /etc/exports

add this line add the bottom:

/fog *(ro,sync,no_wdelay,subtree_check,insecure_locks,no_root_squash,insecure,fsid=2

then finally do the following command to export the directory:

exportfs -a

Check if it it is being exported with:

showmount --exports

Use sudo if necesary

Do note that you still need to create diretories and add drivers yourself.

@THEMCV OK, I understand you may be getting conflicting information here because we are coming at the same problem from different perspectives.

In my scripts I have the drivers (on the fog server) in /images/drivers …
That is what the scripts should be trying to mount. You can use /fog/drivers but you will need to setup an export in NFS to do that. Me being lazy I just used the /images share that was already there.

Looking at the script from Lee’s page this is the line in question

remotedriverpath="/images/drivers/$osn/$machine"

In this case its saying the drivers are in /images/drivers/… on the fog server. Where is /fog/drivers coming from?

THEMCV

@Quazz Okay, I completed this and it’s finished. showmount --exports does show /fog is working. And I added in the drivers that I had in the other location.

THEMCV

@george1421 I really am not sure. I don’t see anything in the script that refers to /fog except in the notation. I added the folder and copied the drivers into there from /images/drivers and am testing it now.

Quazz

@THEMCV Alright, well, I just realized none of this makes sense!

You are correct, the fog folder isn’t referenced anywhere.

I’m guessing the issue is REALLY in your /images/postdownloadscipts/fog.drivers

THEMCV

the /fog mount error has disappeared from the process now @Quazz , but the same “Failed to download driver information”

Quazz

@THEMCV Did you edit the fog.drivers you got from Tom?

Because the default version would mount /images/drivers

Wayne Workman

@THEMCV Remove the >/dev/null 2>&1 part from that command in the script, the one that looks like this:
rsync -aqz "$remotedriverpath" "$clientdriverpath" >/dev/null 2>&1

Then we will be able to see an actual error.

THEMCV

@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.

    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.

Quazz

@THEMCV I do not recommend having commands in the postdownloadscripts, only calls to your scripts.

Move the relevant information into another file, imo.

george1421

@THEMCV Well, hell now I understand where the /fog is coming from. That is NOT in the original script I was referencing. https://forums.fogproject.org/topic/4278/utilizing-postscripts-rename-joindomain-drivers-snapins/29

THEMCV

@george1421 I feel like an idiot. I got them jumbled up in my early stages. Bleh. Okay, so should I take the script that is from your link and use it or do as @Quazz suggested and just include a call to it?

@Wayne-Workman: The message from removing the >/dev/null 2>&1

This rsync lacks old-style --compress due to its external zlib. Try --zz. Continuing without compression.

rsync:` write failed on "/ntfs/Windows/DRV/OptiPlex 980/x64/chipset/PP0H5-A00-00.WUB7/JasperFo.uno": No space left on device (20)
rsync error: error in file IO (code 11) at receiver.c(393) [reciever=3.1.2]

Which doesn’t make much sense as the device does have space.

Quazz

@THEMCV Either works, I personally prefer having a more modular approach because it makes it easier to expand and debug, but it’s mostly personal taste.

THEMCV

@Quazz I just have

. ${postdownpath}fog.drivers

Is that good?

Quazz

@THEMCV Yes, that’s fine.

THEMCV

@Quazz Okay, it’s in there. No change. Still acting like there’s no space left on the device which isn’t true at all. The image is only ~15GB.

Quazz

@THEMCV I’d have to guess your ntfs isn’t being mounted correctly on the client. Most likely it’s trying to rsync to the fog client (which is residing in RAM) which will of course not have space to write to.

How do your scripts look like now?

george1421

@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.

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.
