First of all i must say that i'm totally noob to server management. I've rented a server with 8x3TB HDs and RAID10 installed.

In the Disk Management section (I use windows server) i see two unallocated blocks of 2Tbs and 10Tbs each one. I guess this is normal because the RAID10 gives me only half the amount of disk space i've rented.

So now my question is... if i create a partition, that partition will automatically have a duplication of the data or do i have to do something more?

Thanks in advance for any help/hints.

  • Ah... and i've just seen i can only create a simple volume for the 2Tb unallocated memory and i have no option to create a volume with the 10Tb unallocated memory, why is that? – SaintJob 2.0 Jan 27 '13 at 17:08
  • I take it the RAID is done in software RAID? Something starts to ring a bell with the boot volume using MBR and only being able to use boot volumes up to 2TB...any more than that and you'll need GPR instead. Could you upload a picture of your Disk Management screen? – tombull89 Jan 27 '13 at 17:12

Data will be automatically duplicated on the mirrored sets. You don't have to do anything extra.

Because MBR (master boot record) volumes can be a maximum of 2TB. For larger volumes, you need to go GPT (guid partition table.)

  • My problem now is that i only have one Disk (and has the OS installed in one partition) so i can't convert that disk into GPT. Is there anything i could do about it? – SaintJob 2.0 Jan 27 '13 at 17:37
