Partion a new disk

Dec 15, 2014
I have a dedicated server at SoYouStart(OVH) with Proxmox installed. Today they have replaced a broken disk and this new replaced disk needed to be partion again.

I need this disk layout:
Disklabel type: gpt

Device        Start        End    Sectors    Size Type
/dev/sda1        40       2048       2009 1004.5K BIOS boot
/dev/sda2      4096   40962047   40957952   19.5G Linux RAID
/dev/sda3  40962048   43057151    2095104   1023M Linux RAID
/dev/sda4  43057152 3907018751 3863961600    1.8T Linux RAID

But whatever I try with gpart I cant install BIOS boot on start 40.
I get this:
Command (? for help): n
Partition number (1-128, default 1):
First sector (34-3907029134, default = 2048) or {+-}size{KMGTP}: 40-2048
Information: Moved requested sector from 40 to 2048 in
order to align on 2048-sector boundaries.
Use 'l' on the experts' menu to adjust alignment
Last sector (2048-3907029134, default = 3907029134) or {+-}size{KMGTP}:

Any ideas how to do this?

Why are you partitioning like this?
If the new disk part of OS boot disk, than you need to just copy part. Table from a good disk with "sfdisk "
And add the new disk using commands relative to raid used.
Once all is done and raid is resilvered
Run grub install on new disk.
