Thanks for your help. I can't seem to get the option to convert the drive to a Dynamic disk. Is there away of forcing this?

Question
2TB storage limit in windows2003 server
Hi
I have a windows 2003 server with a raid 5 2.7TB total storage. In Disk manager I have created the maximum amount allowed 2TB basic volume leaving me with over 500GB left. I can't seem to be able to do anything with this 5GB area apart from clicking properties. Any ideas what I can do so I can use this 500GB. The Volume is a basic volume but again I can't seem to upgrade it.
Many thanks

Changing the Disk type to Dynamic will not help you at this point
because the you have a combined 2TB volume size limit per disk.
To get round this you would need to reconfigure your hardware RAID-5
to give you two logical drives from which you can then create spanned
or striped volumes greater than 2TB using a 1024 cluster size.
Of course to use stripe sets or spanned volumes
you will need to convert the resulting Hardware RAID five volumes
to dynamic disks.
You are using hardware RAID or software RAID? Probably hardware raid right? Please check your hardware RAID card limitation. Configure hardware RAID and software RAID (windows 2003) is totally different !! If you need help, please post your hardware RAID card spec or band. We may find the limitation for you.
For NTFS 4/5, Maximum size per volume is 256TB (if using software RAID)

This is the different between basic and dynamic in windows 2003:

Hi dcleaver....
What I am saying the maximum of a volume on a physical disk is 2TB.
To create a volume greater than the 2TB you would need to use more than one physical disk.
You could use disk stripping or volume spanning to achieve this.
Stripe sets and spanned volumes combine the free space on two or more physical disks
to create the volume.
The Hardware RAID setup you have has combined more than 3 hard disks
to create one logical ddrive.
Windows Server sees the logical drive a physical disk
i.e. it is not aware that there is hardware raid 5 in play.
you would need to reconfugure the Hardware RAID
to create more than one harware raid 5 logical drive.
i.e if you have 6 disks making up your hardware raid 5 logical drive,
delete the existing single hardware raid 5 logical disk
and use 3 hardrives to create RAID 5 1 logical drive
and the other three to create another RAID 5 logical dirve.
So in total you would have 2 logical drives which windows will see as 2 physical disks.
In the Server 2003 disk manager, you would then convert the basic disks to dysnamic disks
and create a 52.7TB RAID 0 (Stripe sets without parity) volume that spans the two dynamic disks.
OR if you wish leave them as basic disks and create 2 partitions of 26.3TB.
Here it is in detail:
http://www.microsoft.com/w
So you need at least:
- Windows Server 2003 SP1 (or 64b)
- GPT disk

Is the primary volume set as dynamic? See this information (particularly the last couple of sentences in this first paragraph):
"Basic disks use the same disk structures as those used in Microsoft® Windows NT® version 4.0 and Windows 2000. When you use basic disks, you are limited to creating four primary partitions per physical disk, or three primary partitions and one extended partition that can contain multiple logical drives. Primary partitions and logical drives on basic disks are known as basic volumes. As shown in Table 1.2, basic volumes are limited to 2 TB. Even if you create multiple volumes on a single logical unit, the combined size of all those volumes cannot exceed 2 TB. If you want to use volumes larger than 2 TB, you must use dynamic spanned, striped, or RAID-5 volumes.
Dynamic disks, which offer features not available in basic disks, were introduced in Windows 2000. Dynamic disks contain dynamic volumes, including simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes. Dynamic disks offer greater flexibility for volume management because they use a hidden database, instead of the disk’s partition table, to track information about dynamic volumes on the disk and about other dynamic disks in the server. This flexibility allows you to create spanned, striped (RAID-0), and RAID-5 volumes that exceed the 2-TB size limit of basic volumes. Simple and mirrored volumes cannot exceed 2 TB."
