Error trying to restore GTP partition tables (restorePartitionsTablesAndBootLoaders)

[mr626]

@Tom-Elliott

Sorry, was posting from mobile before.

The exact error is as per the OP:

ERROR TRYING TO RESTORE GPT PARTITION TABLES (restorePartitionTablesAndBootLoaders)

And just prior to that, it is attempting to restore a GPT partition table but can’t find one (and has the message du: cannot access ‘/images/<name of image>/d1.grub.mbr’ : no such file or directory)

Happy to run any tests / debug etc if that is helpful. I am re-reading this thread as when I was viewing on mobile I missed a whole bunch of posts somehow, so there’s a few suggestions on here I haven’t tried yet. Will update as I do

@mr626 what version of fog are you running, it should show in the cloud.

@Tom-Elliott

Hi, Fog is 6303 as per my first post

[mr626]

Ok, I’ve got a workaround that seems to do the trick (for me)

1. Create an image of type ‘single disk, resizable’
2. Capture image
3. In options for the image, select ‘partition 1 only’
4. Deploy

This works for me (tested on one machine so far- Dell optiplex 790, will test on more this afternoon). I should note though- when I created this Windows 7 image originally I made sure that everything was on one partition (ie there isn’t a separate 100mb system partition, just a single partition with everything on it). So the above may not work for everyone.

Hope that helps someone

I have the same issue with all images on the fog server.
If i try to deploy them, I got the error
Restoring Partition Tables (GPT) … du: cannot access ‘/images/*****/d1.grub.mbr : No such file or directory
and so on…

This file doesn’t exist in the images and now I’m not able to download the images. Still waiting for a fix or solution.

@Oleg What version of FOG?

[Sebastian Roth]

@Oleg Please upload the d1.mbr file of one of your images that causes the error. I will have a look and hopefully we will find out what’s going on here.

As well please tell us you FOG version. Did this issue come up after updating to a newer version or has the error always been there (and you just didn’t use resizable images…)??

[Tom Elliott]

@Sebastian-Roth this sounds to me like the error we had with improper file sizes .

@Tom-Elliott @Wayne-Workman 0_1455880449753_d1.zip
The last version I tried with was 6321.
The images were made with an older version of FOG - 32##. Could this be a problem? And all the images were always made with the option “Multiple Partion -single disk”

@Oleg The MBR file looks ok to me:

$ file d1.mbr 
d1.mbr: DOS/MBR boot sector
$ /sbin/fdisk -l d1.mbr

Disk d1.mbr: 1 MiB, 1048576 bytes, 2048 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x0832de2d

Device     Boot    Start       End   Sectors   Size Id Type
d1.mbr1    *        2048   1953791   1951744   953M 83 Linux
d1.mbr2          1953792  21485567  19531776   9.3G 83 Linux
d1.mbr3         21485568  25391103   3905536   1.9G 82 Linux swap / Solaris
d1.mbr4         25391104 486524927 461133824 219.9G 83 Linux

Definitely no GPT or unusual start sector. So I really wonder why this failed. Can you please update to the very latest version. Tom has changed some of the GPT detection code and I hope this should fix things for you as well.

[Tom Elliott]

@Sebastian-Roth It looks like the filesize is 52k. So I do hope/believe an update would fix this issue as well, as I’m completely moved out of the way of using filesizes .

[Sebastian Roth]

@Tom-Elliott No, filesize is 1048576 (1 MB) so I still wonder why it failed. But anyway I’d hope your changes would fix this now!

@Sebastian-Roth @Tom-Elliott
After an update to the current subverion it’s working again. Thanks.
