Mounting nvme drive as storage pool

[yukiriiin_k]

Previous post on reddit showed a tutorial for adding nvme as storage pool:

Many people succeeded based on the comments. But I'm running into a weird issue:

root@Andy_NAS_84TB:~# synopartition --part /dev/nvme0n1 12

I've tried

synopartition --part /dev/nvme0n1 [1-12]

sfdisk -N[1-5] -uS -q -f -j2048 -z4980480 -tfd -F /dev/nvme0n1

The other nvme /dev/nvme1n1 is also tested. Same issue.

Any suggestions?
