Partition problems & FOG

[popoyo]

Hello,

When i try to restore my images saved in NAS to the same PC’s models, I have this error :

EBR signature for logical partition invalid

I saw that Fujitsu creates an extended partition for the System Partition (C:).
My image works in Windows 7 x64 bits.

How can i do to resolv my problem ?
Does Fog support the logicals partitions ?

What version of fog?

[popoyo]

The last version 1.2.0

[Tom Elliott]

@popoyo That is by far the last version.

You may need to reupload the image, but you’d also be best off with FOG Trunk. 1.2.0 had some basic support (better than prior) for linux, but Windows 7 shouldn’t have logical partitions.

That all said, is this image not downloading to the client machine? Is there actually a problem?

Just the error showing does not necessarily mean anything went wrong.

@popoyo If I remember correctly FOG 1.2.0 did support extended partitions only if image type is set to Linux.

Are you sure the system partition is an extended one?? This sounds really strange. Please post the contents of /images/<image-name>/d1.partitions or upload /images/<image-name>/d1.mbr if you don’t have the partitions text file.

You should definitely look into FOG trunk - although not officially released yet it is pretty stable right now and issues are being solved within hours or few days after being posted here in the forums: https://wiki.fogproject.org/wiki/index.php?title=Upgrade_to_trunk

Yes Iam sure it’s an extended partition that Fujitsu creates at the installation step (it’s the Fujitsu’s factory image)
They propose you to partitionning the Disk before the preinstall with their tool (we cannot ignore this step)

Here my mbr file (d1.mbr) : 0_1459841726126_d1.mbr

@popoyo Ok this is what I see in the MBR file:

d1.mbr1 : start=     2048, size=  4196352, Id=27, bootable
d1.mbr2 : start=  4200448, size=972570624, Id= f
d1.mbr3 : start=        0, size=        0, Id= 0
d1.mbr4 : start=        0, size=        0, Id= 0

Type of partition 2 is ‘f’ -> extended partition. Do you have ‘ebr’ file in your image directory? Please show us the output of ls -al /images/<image-name>/

[popoyo]

Here the ls -al Command of the image : 0_1459862880268_fuji contenu.rtf

No I don’t have theses ‘ebr’ files

[popoyo]

Is there a solution for this problem ?

[Tom Elliott]

@popoyo The problem, as it appears to me, is 3 and 4 are not actually defined at all. -f means it’s logical, but there’s no partitions created on the extended layout.

This said, I think FOG Trunk would fix the issue for you, though you would have to re-upload this particular image.

[popoyo]

Thanks for your reply.
I will upgrade to Fog Trunk and I’ll see if it’s better.
Should I export the hosts fist before the upgrade

[Wayne Workman]

@popoyo Making backups is always a good idea. Do a configuration save, and a hosts export too.
