FOG restore only one partition

Tom Elliott · Mar 4, 2016, 1:19 PM

@plegrand that’s my concern though. THe d1.mbr should be created for ALL uploads. Especially the Windows 7 stuff.

Tom Elliott · Mar 4, 2016, 1:19 PM

That isn’t your concern though, that’s mine. Just noting it’s a problem and I don’t know why it’s even happening.

plegrand · Mar 4, 2016, 1:21 PM

@Tom-Elliott i can make other tests if you want

Tom Elliott · Mar 4, 2016, 11:01 PM

I found out why the d1.mbr/d1.grub.mbr file wasn’t being created.

Yes, it’s kind of an important bit. Please update and re-upload the windows 7 guy (as well as your windows xp if you feel up to it.)

I know i’m asking a lot, but I really think we have all the kinks fixed now. (hopefully).

Again, my only worry on the Win 7 is in the case of resizable we do place our own generalized BCD file. I think this can cause issues, but it can be fixed. I don’t remove the original bcd, rather I move it to a BCD.bak

I will test on Monday. Do i have to capture again before ?
I will test for the windows 7 machine and windows XP machine

No problem for me. If i want it works …

@Tom-Elliott Hello

Test Windows 7

Update fog to 4959 / 6609
Restore machine with ghost image
The machine works fine and show 3 partitions
Delete old image with files on fog web interface
Create new image

default: Windows 7
Single Disk - Resizable
Everything

Basic task
Capture

Messages before partclone
Clearing part (/dev/sda2) …Reg file not found
Clearing part (/dev/sda3) …Reg file not found

Files in image directory

d1.fixed_size_partitions
d1.mbr
d1.minimum.partitions
d1.original.fstypes
d1.original.swapuuids
d1p1.img
d1p2.img
d1p3.img
d1.partitions

d1.mbr is present

After capture, windows start without problem !!!

Basic task
Deploy

After deploy task, the machine stay on “Booting…”

I dont know it it’s usefull :

After reading through most of your posts again I noticed that I probably missed a very important detail. You have two different systems, one WinXP and one Win7 but both having three partitions! I somehow got confused by the different sector counts but same number of partitions…

Is this definitely a Windows 7 installation you are trying this on? Then it most probably won’t boot because of this!! On Win7 we need to be able modify the registry because it would hang on booting otherwise!

Can you please restore your Win7 image from ghost again. Then schedule a debug upload task and run the following commands (sda3 is your OS system partition, right?):

mkdir -p /ntfs
ntfs-3g -o force,ro /dev/sda3 /ntfs
find /ntfs -type f -iname "SYSTEM"
...
umount /ntfs
reboot

On a normal system you should see /ntfs/Windows/System32/config/SYSTEM printed from the find command. If you don’t get any output from that you can try find /ntfs -iname "SYSTEM*" to see if there is any backup file of the registry. Maybe ghost is doing some kind of magic??

Tom Elliott · Mar 7, 2016, 11:27 AM

@Sebastian-Roth I’m of the mind this is the BCD issue I was describing earlier.

I’m going to try making a post download script to revert the BCD.

Tom Elliott · Mar 7, 2016, 11:39 AM

Can you try using this script in your /images/postdownloadscripts/revertbcd

#!/bin/bash
[[ $osid != [5-7] ]] && return
getHardDisk
getPartitions $hd
for part in $parts; do
    fsTypeSetting "$part"
    [[ $fstype != ntfs ]] && continue
    dots "Mounting Partition"
    if [[ ! -d /bcdstore ]]; then
        mkdir -p /bcdstore >/dev/null 2>&1
        case $? in
        0)
            ;;
        *)
            echo "Failed"
            debugPause
            echo " * Could not create mount location"
            return
            ;;
        esac
    fi
    ntfs-3g -o force,rw $part /bcdstore >/tmp/ntfs-mount-output 2>&1
    case $? in
        0)
            echo "Done"
            ;;
        *)
            echo "Failed"
            debugPause
            echo " * Could not mount $part to /bcdstore"
            continue
            ;;
    esac
    if [[ ! -f /bcd/Boot/BCD.bak ]]; then
        umount /bcdstore >/dev/null 2>&1
        continue
    fi
    dots "Restoring original BCD"
    mv /bcdstore/Boot/BCD{.bak,} >/dev/null 2>&1
    case $? in
        0)
            ;;
        *)
            echo "Failed"
            debugPause
            umount /bcdstore >/dev/null 2>&1
            echo " * Could not revert BCD File"
            continue
            ;;
    esac
    echo "Done"
    debugPause
    umount /bcdstore >/dev/null 2>&1
done

Change the file to allow the script to run as a script
chmod +x /images/postdownloadscripts/revertbcd

And add to the /images/postdownloadscripts/fog.download

. ${postdownpath}revertbcd

Yes as you said i made tests with 2 machines but each time i precise in my post wich machine i use
At this time i’m testing on a WIndows 7 machine
I made what you ask me to do and i come back

plegrand · Mar 7, 2016, 12:53 PM

@Tom-Elliott Hello
you mean /images/postdownloadscripts/fog.download => /images/postdownloadscripts/fog.postdownload ??
I’m actually deploying image ghost on this machine

plegrand · Mar 7, 2016, 1:43 PM

@Tom-Elliott Hello
then i added the script into

/home/images/postdownloadscripts/revertbcd

then

chmod +x  /home/images/postdownloadscripts/revertbcd

and

add to the /home/images/postdownloadscripts/fog.postdownload
. ${postdownpath}revertbcd

ls -al /home/images/postdownloadscripts/
total 16

but same problem

Sebastian Roth · Mar 7, 2016, 2:51 PM

@plegrand My intuition was right… This is one thing I hate about windows. It does not care much about case-sensitivity in filenames and paths! Someone or some tool made a backup of the original reg-file called ‘SYSTEM’ but named the new file ‘system’. Windows seams to not care and still boots. But FOG/linux cares about it. We have the path for this defined as ‘/ntfs/Windows/System32/config/SYSTEM’ and therefore our scripts won’t find ‘…/config/system’!

I am not sure what to do about it. I don’t think we should change our scripts as this has never happened before and I guess this is very rarely the case. But it’s kind of easy for you to fix. After restoring the Win7 image via ghost please boot in debug upload again and run:

mkdir -p /ntfs
ntfs-3g -o force,rw /dev/sda3 /ntfs
mv /ntfs/Windows/System32/config/system /ntfs/Windows/System32/config/SYSTEM.moved
mv /ntfs/Windows/System32/config/SYSTEM.moved /ntfs/Windows/System32/config/SYSTEM
umount /ntfs

I guess you can rename the file directly from ‘system’ to ‘SYSTEM’ but I have seen cases (probably on VFAT filesystems) where this fails - therefore I suggest two renames. After that you can start the upload via command fog…

@Sebastian-Roth Hello
then after restoring ghost image i launch debug capture task and then

mkdir -p /ntfs
ntfs-3g -o force,rw /dev/sda3 /ntfs
find /ntfs -type f -iname "SYSTEM"
/ntfs/Windows/System32/config/RegBack/SYSTEM
/ntfs/Windows/System32/config/system


mv /ntfs/Windows/System32/config/system /ntfs/Windows/System32/config/SYSTEM.moved
mv /ntfs/Windows/System32/config/SYSTEM.moved /ntfs/Windows/System32/config/SYSTEM

find /ntfs -type f -iname "SYSTEM"
/ntfs/Windows/System32/config/RegBack/SYSTEM
/ntfs/Windows/System32/config/SYSTEM

umount /ntfs/

fog to launch capture task
reboot
After capture windows 7 works fine.

Deploy task
Same problem : stuck on “booting …”

I keep the Tom’s script (revertbcd) may be i should remove it ?

plegrand · Mar 8, 2016, 8:45 AM

@Sebastian-Roth May be i could give you access to this machine if it’s usefull ?

Sebastian Roth · Mar 9, 2016, 2:42 PM

Definitely was useful to get access to the machine. That particular partition layout turned out to be not very easy to handle and FOG stumbled! Those DELL partitions are quite an issue. But I think Tom and I have fixed it all. @plegrand Please upgrade to the very latest version. Then re-upload and try deploy again! Please test both of your machines to see if this is really the same issue.

plegrand · Mar 10, 2016, 7:25 AM

@Sebastian-Roth Hello
do i have to keep the “revertbcd” script ?

Sebastian Roth · Mar 10, 2016, 7:46 AM

@plegrand Please try without it first!

FOG restore only one partition
