M.2 Drive detected by script but not showing in DSM or able to create volume

[alirz1]

Im running this on a HP elitedesk 800 G3 mini PC. It has a SSD and a M.2 nvme drive.
I installed xpenology(DS918+) on it. Only the sata SSD drive is currently showing in DSM.

I've tried running the 3 scripts, the HDD DB, Synology_enable_M2_volume, Synology_M2_volume.

The scripts show me the M.2 drive being detected. But fails to show up in DSM storage manager or even create volume using the script.
Here is the message i get:

`Running from: /volume1/data/Synology_M2_volume-2.0.27/syno_create_m2_volume.sh

nvme0n1 M.2 Drive nvme0n1 - SK Hynix PC300 NVMe SK hynix 256GB

Unused M.2 drives found: 1

1. SHR 1
2. Basic
3. JBOD
   Select the RAID type: 2
   You selected basic

You have a choice of Multi Volume or Single Volume Storage Pool

• Multi Volume Storage Pools allow creating multiple volumes and
  allow you to over provision to make the NVMe drive(s) last longer.
• Single Volume Storage Pools are easier to recover data from
  and perform slightly faster.

1. Multi Volume (DSM 7 default)

2. Single Volume
   Select the storage pool type: 1
   You selected Multi Volume storage pool

3. nvme0n1
   Select the M.2 drive: 1
   You selected nvme0n1

I just installed 1 NVMe drive in a DS720+ and I'm getting the same 0 synostgpool failed to create storage pool! error. When I went to storage manager it showed the storage could be online assembled, but when clicking on "online assemble" it fails.

I'm trying to work out why it works with 2 or more NVMe drives but fails with 1. I have noticed that the single NVMe drive ends up with an extra partition.
