Single Disk Multiple Partition works after a sector by sector but not before, partition problems.
-
Hey Tom,
It is Fog 1.2 running on Ubuntu 13.10
The image is a multiple partition single disk.The project I am working on is to create a customer recovery partition on a laptop so there are currently 4 partitions as follows:
System Reserved F: 100GB NTFS
183GB NTFS
Back up image G: NTFS 50GB
Recovery E: NTFS 5GBThe image previous to this only had the usual system reserved and C:, therefore using a single disk resizable has worked thus far.
So after successfully pulling the new multiple partition image from the host to server, I then tried to push it to a new host to which is failed. (Call this V1)The anomaly occurs when I pull from the host to the server but tell the image to be sector by sector. It pulls as expected ( slowly ) then pushes and overwrites as it should, problem solved. HOWEVER, when I then try and push the previously failed multiple partition image (V1) it pushes fine, windows loads.
My thoughts were it must be something to do with the overwriting of the partition table, obviously the sector by sector forces the new partition table by rewriting the hard drive sector by sector with the new image. However since (V1) will successfully push once the sector by sector has worked, therefore implementing the required partition table but does not work before.
Hopefully that all makes sense and you can shed some light on the situation.
Thanks in advance! -
you need to be more descriptive of the “failure”
does it image all of the partitions, then fail to boot?
does it fail to image any partitions?
does it image any of the partitions?
does it create the partition structure then fail?
does everything go so fast you can’t tell?
are all of the partitions captured in the uploaded image? (there should be a separate d1p<number>.imgfor each partition on the disk in the directory named after the image in /images) -
After recording the error I can confirm some of the details.
It doesn’t begin to image any of the partitions.
It begins with “erasing current mbr/gpt then i get, ebr signature of logical partition invalid read 0x000 required 0xAA55 error reading logical partition”.
To which it then exits fog and reboots. -
Have you tried using the debug mode?

Treat me as a fog noob please…

Easy…
Host Management --> List Hosts --> [Select Host] -->Basic Tasks --> Advanced --> Download-Debug
Then boot the host. i can’t remember all the commands but “fog” will continue on the way to the imaging process. You can then figure out step by step exactly where you fail. If it fails during the partition allocation it will point you to the size of the hard drive.
For example:
Not all 80gb harddrives are 80gb some are 78.1, 79.8, etc. If the “master” upload was 79.8gb and the host to download to is 78.1gb then you need to tweak your “master” upload partition sizes. -

All the laptops are exactly the same model, bought at exactly the same time with all the same spec so space should be a problem. They all have the same master image on them from a previous master image, I just modified the old master to add two new partitions and then uploaded a new master.
The error is debug mode is still the same:
- ebr signature for logical partition invalid
- read 0x000 but should be 0xAA55
- error reading logical partitions
- List may be truncated
- Done
Then it drops out of fog and reboots.

This sounds like a problem that’s been fixed in svn. Particularly where the start sector needs to be specified at 63 but is being forced to start at sector 2048.

I purchase threw a reseller and they say exacly the same thing. But some drives are different models and the “same size”.
Really check.
I was imaging this summer in a lab of 24 and 20 would image without issue but then 4 would crap out. This was my exact issue.
-
I’ve found the instructions for how to download it but would you be able to explain “svn”.
I will open a few of the laptops and check then. I would like to hope that a bulk purchase from dell themselves, everything would be identical. -
Even same model hdd may have similar issues.

Hi
i also have the same error “EBR signature for logical signature partition invalid;…”
As seen above, i ran “Host Management --> List Hosts --> [Select Host] -->Basic Tasks --> Advanced --> Download-Debug”
On the screenshot maybe you’ll see which steps cause the problem, I am a newbie with FOg… I was so glad that finally i was able to upload image on the server (i had the problem with the password and the size on the server was at 0).But here, i have no idea… You are talking about svn issue but I don’t really understand what you mean…
Have to reduce the size of the hardrive of my “Master Computer” and try to deploy it again ?thx,
R.D.

SVN refers to Subversion an update method that allows the developers to distribute incremental patches as the make fixes to the developmental build If you go this route you are essentially running the latest beta every time you run the SVN updater. Several of the issues people are reporting in 1.2 are already fixed in the latest SVN but you can also introduce some strange new ones. If you decide to go this route just be prepared to tinker a bit to get it stable enough for day to day use thankfully the developers are very responsive and helpful. Advances are fast also with a new version almost daily and each one noticeably better the the previous.

Thank you for the quick answer !
Well, I forgot to tell that I m using Ubuntu desktop 12.04, and fog 1.2.
Will it change if I m using an older version of fog of another version of Ubuntu will it work ?
I want to use Fog ! I was using CloneZilla and Drbl before but Fog is really better, offers more functionnalities !
So if changing the version of fog will not change than i ve no other change than using the SVN.
I saw that link: [url]http://www.fogproject.org/wiki/index.php/SVN[/url]
All the patches are included in the same file or i have to install different packages ?
[SIZE=5][B]Ubuntu[/B][/SIZE][SIZE=4][B]Install Subversion[/B][/SIZE]
sudo apt-get update
sudo apt-get install subversion[SIZE=4][B]Download the package[/B][/SIZE]

cd svn
svn checkout [url]https://svn.code.sf.net/p/freeghost/code/trunk[/url][SIZE=4][B]Install It![/B][/SIZE]
cd ~/svn/trunk/bin
sudo ./installfog.shthx

Ubuntu 12.04 should work perfectly fine, in fact I recommend using it over the newest version of Ubuntu. That “package” is the only one you need. Just follow the instructions you copied and you should be good to go. Let us know if you have any issues.
-
I am using 12.04 without any issues also.
-
Thanks !
I did it on the VM and indeed it s easy to install. But i think that during the process i saw Fog 1.3 but after the installation i saw in the web interface fog 1.2. Normal ? it s just a detail anyway.
The install is completed in my test environment but I cannot yet tell you if it s working or not cause in the test, i have only VM with 1 partition and not like in production (not enough place on my laptop…).
I ll give you news tomorrow ! -
HI,
i made the update this morning on my prod server but when i download the image on another computer, i still have the same error message…
Do i need to upload a new image because of the update ?
What info should i provide you ?R.D.
-
I’d recommend upgrading to trunk and see if the issues persist still.
