Description Kamil Páral 2011-09-27 11:42:13 UTC 
Description of problem:
I was following this test case:
https://fedoraproject.org/wiki/QA:Testcase_Anaconda_autopart_(use_all_space)_install

I did a default install in KVM. In the booted system I run:

# parted
GNU Parted 3.0
Using /dev/mapper/VolGroup-lv_root
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) p                                                                
Model: Linux device-mapper (linear) (dm)
Disk /dev/mapper/VolGroup-lv_root: 7114MB
Sector size (logical/physical): 512B/512B
Partition Table: loop

Number  Start  End     Size    File system  Flags
 1      0.00B  7114MB  7114MB  ext4


Please notice that there is "Partition Table: loop" instead of expected "Partition Table: gpt" as the test case requires. However, fdisk says:

# fdisk /dev/vda

WARNING: GPT (GUID Partition Table) detected on '/dev/vda'! The util fdisk doesn't support GPT. Use GNU Parted.


Command (m for help): p

Disk /dev/vda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders, total 20971520 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
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1               1    20971519    10485759+  ee  GPT


That seems like GPT.

Either the test case needs to be corrected or there is something wrong in the GTP installation. I suppose the test case is wrong, but reporting here just to be sure.

Version-Release number of selected component (if applicable):
anaconda 16.19
Fedora 16 Beta RC3 Live x86_64

You are not specifying a device when running parted and it is using your root logical volume which has no partition table, hence "loop".

Try running 'parted /dev/vda' instead.

That works and reports "gpt". I'll fix the test case. Thanks.
