Win 2k8, how to partition a volume beyond 2tb?

Question

RAID

Installed (via LARA in Hetzner) a winserver (from their own distribution) on a pre-created raid-0 volume larger than 10TB. I naively hoped that everything would be marked out and everything would be ok. (Didn't have this experience before).
The system has risen, now I see - and the volume is 2TB in total. I go to the rest of disk management, I see there: a boot volume, a volume with a system and 9 + TB of unallocated space. I can’t create a volume there, I can’t expand the current one.
Found a server acronyms. Tried to convert MBR-LDN. Esteemed at first the help, it seems as it is possible. But it doesn't convert.
What options do I have to occupy that space? And I really need it. Only re-allocation of the array and a new installation of the system? Paying for LARA again :(
PS
Follow-up question:
There is a raid-0 of 4 disks of 3TB each. But the linear write speeds are not higher than 250 MB / sec. What could I mess up when creating an array?

Answer 1

In order to get access to more than 2tb partitions, it is necessary that the disk / raid layout is carried out not in mbr, but for example in gpt, since mbr, by its structure, cannot address further. It is worth Google how to convert a disk to gpt and how to keep the bootloader working. I did the operation, but on the contrary gpt-> mbr, but loaded Windows through grub.
