Hi Nish,
I think I have found what I needed and I have made a patched version of dmraid
and uploaded to my ppa.
This will affect the way that it detects the pdc raids so please make sure you
have everything backed up (its probably best done from a live CD).
If it works as I expect it will you

The version of gparted in my ppa doesn't rely on kpartx like the repository
version. It should leave dev names alone but the repository version seems to
screw them up adding a p in sometimes.
The next version of dmraid will leave the p in there, there is a discussion on
this in this bug:
To use the script open a terminal and make a clean directory to work in and
place the thh dump-pdc-metadata.sh in there (extracted from the archive I
uploaded).
Make the script executable and then run it.
chmod a+x dump-pdc-metadata.sh
./dump-pdc-metadata.sh
It will ask you for your password
is this ok?

Yep that's perfect.
The second metadata chunk is there for me to investigate.
I will let you know when I find a solution.
Thanks!

Hi,
The 64-bit version has now been built.
So you should be able to upgrade.
To check the installed version you can use dpkg, the program version will
always remain the same.
dpkg -p dmraid | grep Version
Once upgraded it should output:

# dpkg -p dmraid | grep Ver

Hmmm. It didn't quite output what I wanted, sorry about that.
I have made another patched version which is more verbose and should
show each meta location it tries (weather it finds it or not).
Unfortunately there is a bit of a wait in the ppa build queue at the moment.

Annoyingly the metadata only contains the information for the first raid set
(which is fine of course). The other set will be another metadata block.
We can dump this metadata manually but we need to know where its located.
To do this I will patch a version of dmraid that will output these

Well we need to determine which software the bug is in.
How are you determining that Ubuntu and Fedora can't see the full amount?
E.g what program are you using for partitioning.
Could you please post the output of (in ubuntu and centos):
sudo dmraid -ay -vvv -d
This will help us!

I have just been looking at the sources for the centos dmraid package for the
pdc. (Promise controller)
The only difference is a Raid10 patch but won't affect you as you are not using
that.
I am inclined to believe the bug is in whatever program you are using
for partitioning.

Right.
The bug is definitely in dmraid. (Disk size reported my dmraid is wrong by

Could you post a metadata dump please. This will allow me to explore the
metadata and see if something is different to what it expects.
To do a metadata dump run the following

It dumps to a directory without saying anything.

I've just had another thought.
Are you trying the 64-bit version of Ubuntu?
32-bit addressing will only go up to 2.2TB so it might be worth trying 64-bit
Ubuntu instead.
2.5TB - 2.2TB = 300GB (Sound familiar?)
But dmraid will not handle two separate arrays on one disk.
If 64-bit sees the array
I also believe for disks that size you need to use a GPT partition
table.

Thank you for taking the time to report this bug and helping to make
Ubuntu better. This bug did not have a package associated with it, which
is important for ensuring that it gets looked at by the proper
developers. You can learn more about finding the right package at
I think your issue may be caused by the fact that dmraid cannot handle
two seperate arrays on one disk set.
The best way to do it is have the RAID0 set as the entire set (all 4.5TB) and
then partition into smaller chunks.
Please try this first!
