[Bug 1089096] [NEW] Incorrect size detected

[StormSurfer]

Public bug reported:

I susspect that dmraid does not correctly detect the isw RAID 1
(mirroring) volume size and maps the volume incorrectly.

I configured it through the BIOS raid tool and windows 7  partitioned it with GPT to access all disk space. 
The volume should be around ~3 TB windows 7 reports this correctly and can access all partitions. 

I attached a few files that contain the various dmraid command line tool
output's. and the dmesg log where the device-mapper reports that the
size is invalid.

As you can see in parted 'parted -l' it crached on the volume access so
i could not get any more info.  gparted only showed a volume size of
746.52Gb.
