Disk Management 2TB issue in 2008

[Guest jas0n]

I have a HP DL320s, currently with 6 * 750GB SATA disks in a single

logical drive, raid 6 of 2861491MB

 

Windows 2008 x64 has been installed using a 50GB system partition and

the plan was to create a couple of 1TB Volumes with the third volume

using the remaining space and to add disk as needed.

 

The server is just a low use basic file server.

 

The Disk in DIsk Management shows as Disc0 Basic with the 50GB parition,

layout simple, type basic, ntfs.

 

The problem is the remaining unallocated disk shows as 2 separate

sections, one of 1998GB and the other as 746.42GB.

 

I can create new simple volumes in the 1998GB section but all the

options are greyed out on the 746GB section, cannot create anything with

this one.

 

Diskpart also shows:-

 

Disk ### Status Size Free Dyn Gpt

-------- ---------- ------- ------- --- ---

* Disk 0 Online 2794 GB 1998 GB

 

What would be causing this?

Perhaps this is "service partition" built by HP install utility.

 

Can you show us results of the command

DISKPART> list par

Smart start would not recognise the size correctly either, donloaded

latest version so couldnt install with smart smart, installed via

standard 2008 windows install and adding the support pack once

installed.

 

The array config shows the correct sizes and I deleted all and recreated

before going ahead with 2008 install. It just shows 1998gb free instead

of the whole unused space.

 

diskpart result:-

 

DISKPART> list disk

 

Disk ### Status Size Free Dyn Gpt

-------- ---------- ------- ------- --- ---

Disk 0 Online 2794 GB 1998 GB

 

DISKPART> select disk 0

 

Disk 0 is now the selected disk.

Hm, I am confused :-(

 

In your first message you state

<quote>

The problem is the remaining unallocated disk shows as 2 separate

sections, one of 1998GB and the other as 746.42GB.

</quote>

 

Now the diskpart shows:

 

<quote>

DISKPART> list disk

 

Disk ### Status Size Free Dyn Gpt

-------- ---------- ------- ------- --- ---

Disk 0 Online 2794 GB 1998 GB

</quote>

 

Well, this 746.42GB hidden partition must have been created somehow.

 

I don't know how to erase it with diskpart if diskpart doesn't show it.

I've been also using GDISK32.EXE that comes with Symantec Ghost Enterprise

Solution Suite.

I've prepared a Windows PE DVD and put this tool on it.

I would use this tool to see how the disk is partitioned.

Example:

Boot into windows PE and navigate to folder where you copied your tools (my

folder is \TOOLS).

GDISK32.EXE 0 /STATUS ' This would list partitions on Disk 0

GDISK32.EXE 0 /DEL /P:2 ' This would delete for example Partn 2 on Disk 0

(hopefuly hidden partition).

 

Failing that, I'm afraid I would boot into Windows PE and using diskpart

wipe the whole disk.

Example

diskpart

select disk 0

clean

 

I would then proceed to create partitions:

create part primary size 50000 ' this would create system/boot partition.

format quick

active 'this would mark partition active.

assign 'this would assign drive letter

 

I would then (still in Win PE) proceed to see if I get expected free size.

list par

 

If I get expected free size, I'd proceed creating second partition.

Example

create partition primary ' If we don't specify size, the whole free space of

the disk will be taken.

assign ' we assign drive letter

format quick

 

I would then proceed installing OS (Win 2008)

 

If that fails, I'm afraid I would need to call HP support.

 

Best of luck jas0n, and keep us informed.

Ok, turns out to be:-

 

boot/system partition cannot be on 2TB+ volume as to see 2tb+ disk needs

to be gpt and cant convert to gpt as cant then boot to a gpt disk.

 

ended up using 2 small disks for raid1 boot/system volume, separate

raid6 gpt datapartition of > 2TB.
