[issue1339] partition table consistency

[George Skillas]

New submission from George Skillas <gskillas at gmx.de>:

Hello together,

the issue in words: Something seem sto be messed up (or at least
gdisk/parted/gparted think so) with the partition table.
I am using an 256 MiB USB drive and would like to create an additional partition
after the one in the ISO. However the
partition table manipulation tools fail to recognize the ISO partition altogether.

Best regards

George

chalki:~ # gdisk /dev/sdc
GPT fdisk (gdisk) version 0.8.7

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: present

Found valid MBR and GPT. Which do you want to use?
 1 - MBR
 2 - GPT
 3 - Create blank GPT

Your answer: 2
Using GPT and creating fresh protective MBR.
Warning! Main partition table overlaps the first partition by 34 blocks!
You will need to delete this partition or resize it in another utility.

Command (? for help): p
Disk /dev/sdc: 511488 sectors, 249.8 MiB
Logical sector size: 512 bytes
Disk identifier (GUID): 956177C9-6B4F-41C4-AC7F-3014E2B927A3
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 511454
Partitions will be aligned on 4-sector boundaries
Total free space is 115610 sectors (56.5 MiB)

Too few arguments.
======================
libparted : 2.4
======================
/dev/sdc contains GPT signatures, indicating that it has a GPT table.  However,
it does not have a valid fake msdos partition table, as it should.  Perhaps it
was corrupted -- possibly by a program that doesn't understand GPT partition
tables.  Or perhaps you deleted the GPT table, and are now using an msdos
partition table.  Is this a GPT partition table?

The backup GPT table is not at the end of the disk, as it should be.  This might
mean that another operating system believes the disk is smaller.  Fix, by moving
the backup to the end (and removing the old backup)?
Not all of the space available to /dev/sdc appears to be used, you can fix the
GPT to use all of the space (an extra 114176 blocks) or continue with the
current setting? 
Unable to satisfy all constraints on the partition.
Too few arguments.
